After the separation of the ores from the crude matter. The gold ore is now further pulverized under pressure into fine particles. After the ores has been pulverized into the desired sizes. The grounded gold ore will now be further subjected to temperature above the melting pint old gold (1064℃).

It is obvious that the most suitable treatment for ores carrying gold and silver associated with pyrite and other iron sulphides, arsenopyrite or stibnite, will depend on the type of association. Cyanidation is usually the most suitable process, but it often necessitates grinding ore to a fine size to release the gold and silver.

Gold-Silver Separation. The initial step is to weight the Dore metal. Since silver is leached by nitric acid and gold no, the next step is to attack the Dore metal with a hot diluted solution of nitric acid. The acid dissolves the silver and leaves the gold that has to be rinsed, dry, and weight on a scale of high sensibility such as 0.001 mg.

An arrastra (or arastra) is a primitive mill for grinding and pulverizing (typically) gold or silver ore.Its simplest form is two or more flat-bottomed drag stones placed in a circular pit paved with flat stones, and connected to a center post by a long arm.

Gold and mercury quickly form an alloy, so people have used mercury amalgamation for centuries to extract gold from ore. The ore must be thoroughly clean to ensure optimum contact between the gold in the ore and the introduced mercury. One way to clean it is to wash the ore in a solution of nitric acid.

They sometimes used mercury, which forms an amalgam with small particles of gold and silver. Miners used mechanical crushing and grinding machines to break up ores for further processing. Early miners used Mexican arrastras or stamp mills, which reached their peak in the late nineteenth century, to crush ores into sand-size particles.

Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam).Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as color) embedded in rock minerals.. Ores in which gold occurs in chemical composition with other ...

To combat this weakness, gold is usually alloyed with another member of the metal family such as silver, copper, platinum, or nickel. Gold alloys are measured by karats (carats). A karat is a unit equal to 1/24 part of pure gold in an alloy. Thus, 24 karat (24K) gold is pure gold, while 18 karat gold is 18 parts pure gold to 6 parts other metal ...
