Using Ball Mills to Extract Raw Gold from Ores
Its major purpose is to perform the grinding and blending of rocks and ores to release any free-gold that is contained within them. At major mines, the mill was the critical equipment that was required to process the ores that were extracted from deep underground. Many early mines used stamp mills, but many operations today find that Lime reagent utilization efficiency can be defined as the mass percentage of the lime reagent participating in the target reaction(s). Utilization efficiency is not generally explicitly determined in gold processing operations, although it is an important consideration when comparing lime reagents and can readily be determined under laboratory Lime use in gold processing A review ScienceDirect
