Jan 23, 2012· Step #6 – Mining samples and determining processing. Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore. This is done in order to determine the appropriate processing technique. Step #7 – Processing (on-site) Once ore is extracted, processing it into pure gold must be done.
Recovery in block caving varies with conditions and is influenced by the amount of dilution the ore can stand, since high recovery usually involves high dilution also, and the amount of dilution permissible depends on metal prices.
Existing processes for the recovery of platinum group metals (PGM) from UG-2 ores place stringent requirements with regard to chromite content upon feed material to the plant.

Underlying physical and chemical processes of formation are common to many metallic and nonmetallic ore deposits. A good deal of data is lacking about the processes of ore formation, ranging from how metals are released from source rocks through transport to deposition and post-deposition alteration.
Sep 24, 2014· The technology to release precious metals from sulfide ores is neither unknown, mysterious or new. Big mining companies do this every day of the year. No big mining company uses plasma to heat these ores because its totally unnecessary, and plasma is expensive.
recovery of the precious metals to produce doré bullion bars. Grinding and sizing. Ore processing is a 24 hour operation.
