  • Gold processing Britannica

    Gold processing, preparation of the ore for use in various products. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability. The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms ...

  • Gold The Canadian Encyclopedia

    ProductionGold in CanadaAboriginal Participation in Gold MiningSustainable MiningThere are various ways to separate and recover gold, depending upon the nature of the ore. When gold occurs in a relatively coarse, free state, it can be recovered by mechanical means such as gravity traps and shaking tables, where the gold separates out because of its high specific gravity. Cyanidation is a chemical process used to recover gold that is very finely distributed in the ore. The process is complex; it involves adding a cyanide solution to finely ground ore and then agitating it in the presence of air to dis
  • Gold processing - Mining and concentrating Britannica

    Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury, by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel, or by grinding the ore in a ball, rod, or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury.

  • Extracting Gold HowStuffWorks

    To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In these drums, the ore is ground to a fine slurry or powder.
