Ancient gold smelting rare today. extract recovery process of refining gold to remove any impurities
 
10:32
►► http://www.goldextractionprocess.com 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 quest for purer and finer examples of gold.

Interesting to know. Mining and production of silver
 
03:30
This publication with the heading “Interesting to know” is dedicated to silver mining and production. The process of silver mining and processing is similar to gold production. First step is ore extraction with the help of surface mining or mine building. The second step is ore beneficiation and receiving of powder concentrate. The final step is refining and getting fine metals in the form of ingots, granules or chemical compounds.

Free Gold, Silver, Copper & Minerals From Mine Slag!
 
02:59
Imagine finding high grade free gold, silver & copper ore. Then finding those same elements in something that's already been refined? Old refining techniques at this onsite refinery only yielded as high as 60% recovery rate for this sulphide ore that was mined. Some of these elements are found as free mill and some appear to still be in there sulphide form. We found a small waste pile of mine slag while gold prospecting one of our properties in BC, near an old mine on one of our hardrock mining claims. About 3-5% would be graded about the same as the assay done at the end of the video. These are left in a pile near the old mine dump. Pieces of almost pure copper can still be found as melted nuggets. Slag is the glass like by product left over after a desired such as gold, silver, copper, lead....ect.. metal has been separated or smelted from its natural ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. Just for fun an assay was done on a small sample. Yeilding some good gold, silver, copper and lead values the results are at the end of the video! This video was made possible by our patrons listed below!

Silver Mining Documentary - How Silver Is Mined and Reformed - Prehistoric TV
 
42:25
Silver Mining Documentary - How Silver Is Mined and Reformed - Prehistoric TV Silver is a chemical element with symbol Ag (from the Latin argentum, derived from the Greek ὰργὀς: "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Silver is used in numerous applications other than currency, such as solar panels, water filtration, jewellery, ornaments, high-value tableware and utensils (hence the term silverware), and as an investment medium (coins and bullion). Silver is used industrially in electrical contacts and conductors, in specialized mirrors, window coatings, and in catalysis of chemical reactions. Silver compounds are used in photographic film and X-rays. Dilute silver nitrate solutions and other silver compounds are used as disinfectants and microbiocides (oligodynamic effect), added to bandages and wound-dressings, catheters, and other medical instruments.

Subscribe to this ►► Subscribe https://goo.gl/93XuWY ✔️ THANK YOU ✔️ Aqua regia (Latin, lit. "royal water" or "king's water") is a mixture of nitric acid and hydrochloric acid,optimally in a molar ratio of 1:3. Aqua regia is a yellow-orange fuming liquid. Aqua regia was so named by alchemists because it can dissolve the noble metals gold and platinum. However, aqua regia does not dissolve or corrode silver, titanium, iridium, ruthenium, rhenium, tantalum, niobium, hafnium, osmium, or rhodium. Applications Aqua regia is primarily used to produce chloroauric acid, the electrolyte in the Wohlwill process. This process is used for refining the highest quality (99.999%) gold. Aqua regia is also used in etching and in specific analytic procedures. It is also used in some laboratories to clean glassware of organic compounds and metal particles. This method is preferred over the "traditional" chromic acid bath for cleaning NMR tubes, because no traces of paramagnetic chromium can remain to spoil spectra. While chromic acid baths are discouraged because of the high toxicity of chromium and the potential for explosions, aqua regia is itself very corrosive and has been implicated in several explosions due to mishandling. Due to the reaction between its components resulting in its decomposition, aqua regia quickly loses its effectiveness (yet remains a strong acid), so its components are usually only mixed immediately before use. While local regulations may vary, aqua regia may be disposed of by careful neutralization, before being poured down the sink. If there is contamination by dissolved metals, the neutralized solution should be collected for disposal. Chemistry Dissolving gold. Pure gold precipitate produced by the aqua regia chemical refining process Aqua regia dissolves gold, though neither constituent acid will do so alone, because, in combination, each acid performs a different task. Nitric acid is a powerful oxidizer, which will actually dissolve a virtually undetectable amount of gold, forming gold ions (Au3+). The hydrochloric acid provides a ready supply of chloride ions (Cl−), which react with the gold ions to produce tetrachloroaurate(III) anions, also in solution. The reaction with hydrochloric acid is an equilibrium reaction which favors formation of chloroaurate anions (AuCl4−). This results in a removal of gold ions from solution and allows further oxidation of gold to take place. The gold dissolves to become chloroauric acid. In addition, gold may be dissolved by the free chlorine present in aqua regia. Appropriate equations are.

"Gold mining and the life of gold miners in South Dakota, as seen by the mining company." Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. 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). https://en.wikipedia.org/wiki/Gold_mining Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Gold mining is the removal of gold from the ground. There are several techniques and processes by which gold may be extracted from the earth. Placer mining Panning Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan. The panning material is usually removed from stream beds, often at the inside turn in the stream, or from the bedrock shelf of the stream, where the density of gold allows it to concentrate, a type called placer deposits. Gold panning is the easiest technique for searching for gold, but is not commercially viable for extracting gold from large deposits, except where labor costs are very low or gold traces are substantial. Panning is often marketed as a tourist attraction on former gold fields. Before large production methods are used, a new source must be identified and panning is useful to identify placer gold deposits to be evaluated for commercial viability. Sluicing Using a sluice box to extract gold from placer deposits has long been a common practice in prospecting and small scale mining. A sluice box is essentially a man made channel with riffles set in the bottom. The riffles are designed to create dead zones in the current to allow gold to drop out of suspension. The box is placed in the stream to channel water flow. Gold bearing material is placed at the top of the box. The material is carried by the current through the box where gold and other dense material settles out behind the riffles. Less dense material flows out of the box as tailings. Larger commercial placer mining operations employ screening plants, or trommels, to remove the larger alluvial materials such as boulders and gravel, before concentrating the remainder in a sluice box or jig plant. These operations typically include diesel powered, earth moving equipment, including excavators, bulldozers, wheel loaders, and rock trucks. Dredging Although this method has largely been replaced by modern methods, some dredging is done by small scale miners using suction dredges... Gold ore processing In placer mines, the gold is recovered by gravity separation. For hard rock mining, other methods are usually used. Cyanide process Cyanide extraction of gold may be used in areas where fine gold bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold cyanide or silver cyanide solution. Zinc is to precipitate out residual zinc as well as the silver and gold metals. The zinc is removed with sulfuric acid, leaving a silver or gold sludge that is generally smelted into an ingot then shipped to a metals refinery for final processing into 99.9999% pure metals. Advancements in the 1970s have seen activated carbon used in extracting gold from the leach solution. The gold is absorbed into the porous matrix of the carbon. Activated carbon has so much internal surface area,[5] that fifteen grams (half an ounce) has the equivalent surface area of the Melbourne Cricket Ground (18,100 square metres (195,000 sq ft)). The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning... The cyanide technique is crude and is commonly used in low grade gold and silver ore processing. There are many environmental hazards associated with this extraction method in addition to the high toxicity of the cyanide itself. An acute example was demonstrated in the 2000 Baia Mare cyanide spill environmental disaster when a break in a waste pond dam gold mine reprocessing facility near Baia Mare in northern Romania released approximately 100,000 cubic metres (3,500,000 cu ft) of waste water contaminated with heavy metal sludge and up to 120 long tons (122 t) of cyanide into the Tisza River...

Smelting and Gold Refining Part 1: Smelting sulfides and black sands to recover gold/silver
 
09:26
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.
