How Is Gold Processed? | Reference.com Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process. How gold is made - history, used, parts, procedure ...

Ore processing – Waihi Gold The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ‘see’ the gold in the leaching process. Free Gold | Gekko - Mineral Processing Solutions Free Gold Recovery. After crushing ore clumps to a manageable size of 20mm or less, via the Python or other crushing circuit, Gekko offers a range of free gold recovery options..
