• Ancient gold smelting rare today. extract recovery process of refining gold to remove any impurities

    Smelting of rare antique gold. The process of refining gold to remove any impurities that may be found intermixed with the noble metal is an ancient practice that has long been employed by diverse cultures. One of the earliest gold refining equipments employed by ancient metallurgists was the blast furnace – by then a rudimentary structure built with clay, stone, or roughly hewn rocks which were fed with wood or an assortment of biofuels derived from the dried fecal matter of animals. The blast furnace was used in tandem with the crucible, one of the oldest and perhaps still widely used metallurgical instruments to this day. With the methods of gold refining being perfected through the decades, even rustic objects such as clay pots and later on, cast iron equipment were employed in the que...

    This is a video showing one potential way to recover the gold and silver values from the sulfide and black sand concentrates that come off our shaker table. These concentrates still can have appreciable gold values even when the free gold has been removed. When the concentrates to be smelted do not contain a sufficiently high precious metal content (between 25%-50% precious metals) a collector metal must be used to draw the precious metals to the bottom of the conical mold to ensure the recovery of the gold and silver. I have been using copper as a collector metal due to its low cost and ease of refining after smelting.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ https://en.wikipedia.org/wiki/Silicon_carbide Silicon carbide (SiC), also known as carborundum /kɑːrbəˈrʌndəm/, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide such as light-emitting diodes (LEDs) and detectors in early radios were first demonstrated around 1907. SiC is used in semiconductor electronics devices that operate at high temperatures or high voltages, or both. Large single crystals of silicon carbide can be grown by the Lely method; they can be cut into gems known as synthetic moissanite. Silicon carbide with high surface area can be produced from SiO2 contained in plant material... Wide-scale production is credited to Edward Goodrich Acheson in 1890. Acheson was attempting to prepare artificial diamonds when he heated a mixture of clay (aluminum silicate) and powdered coke (carbon) in an iron bowl. He called the blue crystals that formed Carborundum, believing it to be a new compound of carbon and aluminum, similar to corundum. In 1893, Henri Moissan discovered the very rare naturally-occurring SiC mineral while examining rock samples found in the Canyon Diablo meteorite in Arizona. The mineral was named moissanite in his honor. Moissan also synthesized SiC by several routes, including dissolution of carbon in molten silicon, melting a mixture of calcium carbide and silica, and by reducing silica with carbon in an electric furnace. Acheson patented the method for making silicon carbide powder on February 28, 1893. Acheson also developed the electric batch furnace by which SiC is still made today and formed the Carborundum Company to manufacture bulk SiC, initially for use as an abrasive. In 1900 the company settled with the Electric Smelting and Aluminum Company when a judge's decision gave "priority broadly" to its founders "for reducing ores and other substances by the incandescent method". It is said that Acheson was trying to dissolve carbon in molten corundum (alumina) and discovered the presence of hard, blue-black crystals which he believed to be a compound of carbon and corundum: hence carborundum. It may be that he named the material "carborundum" by analogy to corundum, which is another very hard substance (9 on the Mohs scale). The first use of SiC was as an abrasive. This was followed by electronic applications. In the beginning of the 20th century, silicon carbide was used as a detector in the first radios. In 1907 Henry Joseph Round produced the first LED by applying a voltage to a SiC crystal and observing yellow, green and orange emission at the cathode. Those experiments were later repeated by O. V. Losev in the Soviet Union in 1923... https://en.wikipedia.org/wiki/Aluminium_oxide Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al2O3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide. It is commonly called alumina, and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. It occurs naturally in its crystalline polymorphic phase α-Al2O3 as the mineral corundum, varieties of which form the precious gemstones ruby and sapphire. Al2O3 is significant in its use to produce aluminium metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point...

In appearance, scandium is a shiny metal with a yellowish tint due to the scandium oxide layer covering the metal. Because of its rarity and high chemical activity, scandium has a very high price to it. This piece of scandium, weighing 1.3 grams, costs about $40. Its density is 2.98 g / cm3, only by 10% more than that of aluminum. However, the melting point of scandium is much higher (1541 °C. Interestingly enough, scandium chips in a jar when shaked produce a very interesting sound. It is quite resonant, I can assume that this is due to the lightness and hardness of scandium. By its chemical properties, scandium resembles aluminum and lanthanides. Chips of scandium burn well in the air, and during the combustion you can hear this interesting raspy sound. From the heat of the reaction the produced scandium oxide melts and forms into a ball. If you try to rub scandium into a file, you will not see scandium powder spontaneously igniting in the air. Scandium reacts well with acids, such as the hydrochloric acid. In this reaction scandium chloride is produced, in many compounds scandium has the oxidation state of +3. Besides acids, scandium can also react with alkali to form skandate - the complex compounds of scandium. By this characteristic scandium is quite similar to aluminum, it has the ability to react with acids and alkalis, which means it’s amphoteric. Scandium finds many uses in the world. Scandium is often used as a dopant for the aluminum alloys, even a simple addition of 0.4% scandium increases the strength of the alloy by 30%. Expensive bicycles are made from this alloy. Scandium iodide is added to mercury gas lamps that produce very authentic looking artificial light similar to the sunlight. In the nuclear industry hydride and deuteride scandium are used for them being excellent neutron moderators. Also scandium compound are used for the creation of luminophores in microelectronics and in the production of solar batteries. Scandium does not have any biological role.

It is a silvery white, soft, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. The chief ore of aluminium is bauxite. Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates. Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically... General use Aluminium is the most widely used non-ferrous metal. Global production of aluminium in 2005 was 31.9 million tonnes. It exceeded that of any other metal except iron (837.5 million tonnes). Forecast for 2012 is 42–45 million tonnes, driven by rising Chinese output. Aluminium is almost always alloyed, which markedly improves its mechanical properties, especially when tempered. For example, the common aluminium foils and beverage cans are alloys of 92% to 99% aluminium. The main alloying agents are copper, zinc, magnesium, manganese, and silicon (e.g., duralumin) and the levels of these other metals are in the range of a few percent by weight... The metal was first produced in 1825 in an impure form by Danish physicist and chemist Hans Christian Ørsted. He reacted anhydrous aluminium chloride with potassium amalgam, yielding a lump of metal looking similar to tin. Friedrich Wöhler was aware of these experiments and cited them, but after redoing the experiments of Ørsted he concluded that this metal was pure potassium. He conducted a similar experiment in 1827 by mixing anhydrous aluminium chloride with potassium and yielded aluminium. Wöhler is generally credited with isolating aluminium (Latin alumen, alum). Further, Pierre Berthier discovered aluminium in bauxite ore. Henri Etienne Sainte-Claire Deville improved Wöhler's method in 1846. As described in his 1859 book, aluminium trichloride could be reduced by sodium, which was more convenient and less expensive than potassium used by Wöhler. In the mid 1880s, aluminium metal was exceedingly difficult to produce, which made pure aluminium more valuable than gold. So celebrated was the metal that bars of aluminium were exhibited at the Exposition Universelle of 1855. Napoleon III of France is reputed to held a banquet where the most honored guests were given aluminium utensils, while the others made do with gold. Aluminium was selected as the material to use for the 100 ounces (2.8 kg) capstone of the Washington Monument in 1884, a time when one ounce (30 grams) cost the daily wage of a common worker on the project (in 1884 about $1 for 10 hours of labor; today, a construction worker in the US working on such a project might earn $25-$35 per hour and therefore around $300 in an equivalent single 10-hour day). The capstone, which was set in place on 6 December 1884, in an elaborate dedication ceremony, was the largest single piece of aluminium cast at the time. The Cowles companies supplied aluminium alloy in quantity in the United States and England using smelters like the furnace of Carl Wilhelm Siemens by 1886... Hall-Heroult process: availability of cheap aluminium metal Charles Martin Hall of Ohio in the U.S. and Paul Héroult of France independently developed the Hall-Héroult electrolytic process that facilitated large-scale production of metallic aluminium. This process remains in use today. In 1888 with the financial backing of Alfred E. Hunt, the Pittsburgh Reduction Company started, today it is known as Alcoa. Héroult's process was in production by 1889 in Switzerland at Aluminium Industrie, now Alcan, and at British Aluminium, now Luxfer Group and Alcoa, by 1896 in Scotland...

here we show a process of pouring a bar commonly called a Dore' bar, depending on the amount of varied ingredients in the flux will determine which kind of metals will be poured,.. this type of mining is common here in the desert southwest because of rare earth metals and platinum groups,.. kind of a shoddy video, sorry about that,.. but i wanted to get it on tape so people could see kind of how it looks to do the process,.. this particular ore came from cracks nearby the ore body through erosion, commonly called caliche', within this outer ore body was little ore cracks with small crevices of quartz, all containing nano particles of gold

This is a video showing one potential way to recover the gold and silver values from the sulfide and black sand concentrates that come off our shaker table. These concentrates still can have appreciable gold values even when the free gold has been removed. When the concentrates to be smelted do not contain a sufficiently high precious metal content (between 25%-50% precious metals) a collector metal must be used to draw the precious metals to the bottom of the conical mold to ensure the recovery of the gold and silver. I have been using copper as a collector metal due to its low cost and ease of refining after smelting. I will be very interested to hear from you all what you think of the video and if you have any suggestions or tip for future smelts for higher recovery.
