Minerals Gekko Systems

Because cyanide cannot always leach sulphide-associated gold, regrinding the ore is typically required to expose the free gold for recovery by intensive leaching. Critically, the size at which one can efficiently liberate gold from the host mineral of the particle will determine the process to use for optimal gold

What is Gold Ore worth? High Grade Mining Ore

Ore is defined as “a naturally occurring mineral containing a valuable constituent (as metal) for which it is mined and worked”. In other word, ore is the most basic raw form of a mineral, which requires additional processing for the valuable minerals (gold) to be removed. A single piece of gold ore generally has very little actual gold
