New Gold Mirrors Aid Investigation of Chemical Separations

"Chemical separation is a very big deal," he said. "Anytime you want something to have a certain level of purity, you have to separate out the compounds you don't want. Separations can be used in pharmaceuticals, fine chemicals, cosmetics — everything has some aspect of separation." Get price

Assay Certificate of Authenticity (COA) Defined

Learn about the assaying process, types of assay cards, and gold and silver bullion products that come with an assay/COA. An assay is an analysis designed to measure and test the composition in ore, alloys, and precious metals. With respect to precious metals, specifically silver and gold, it is a way to make sure that all the coins or bars produced in a mint meet the correct purity standards Get price

Pyrite Mineral

The mineral's gold color, metallic luster, and high specific gravity often cause it to be mistaken for gold by inexperienced prospectors. However, pyrite is often associated with gold . The two minerals often form together, and in some deposits pyrite contains enough included gold to warrant mining. Get price

Gold parting

Gold parting is the separating of gold from silver. Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum. With Get price

Mining Techniques of the Sierra Nevada and Gold Country

Panning was the oldest and simplest way to separate gold from surrounding rock. It was the most basic method to obtain placer gold. The basic procedure was to place some gold-bearing materials, such as river gravel, into a shallow pan, add some water, and then carefully swirl the mixture around so the water and light material spilled over the side. Get price

Gold extraction

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of Get price

Cyanide Leaching Of Gold

Carbonaceous gold ores can have the carbon adsorb the gold onto its surface, and as a result will not be recovered from the pregnant solution. Leaching gold from sulfide ores is difficult, at best. Generally, the recovery for cyanide leaching of sulfide or refractory ores is Get price

Final Clean

Once all the black sands are gone, you can pick out the pieces of platinum if present, and separate them from the gold. Pour the gold into the same gold sample jar used in the earlier steps. This dry process (Steps 1-7) goes very quickly if an effort was made during the final wet stages to get as much black sand and other waste material as possible separated from the gold. Get price
