Based on the gold recovery and mineral processing techniques required, gold ores are commonly classifi ed into two major categories: free-milling and refractory ores. Typically, free-milling ores are defi ned as those where over 90% of gold can be recovered by conventional cyanide leaching. Refrac-tory ores give low gold recoveries or give ...

Types of ore. Gold occurs principally as a native metal, i.e., gold itself.Sometimes it is alloyed to a greater or lesser extent with silver, which is called electrum.Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as colour) embedded in rock minerals..

Gold cyanidation - Wikipedia
Gold cyanidation (also known as the cyanide process or the MacArthur–Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver,
