Historic Gold Ore processing methods Nevada Outback
Methods of processing gold ore using historic proceedures. Very few gold-bearing lodes contain nothing but free gold; on the contrary, they carry the bulk of their values in the form of sulfides, having more or less gold incorporated, and even when the gold is native and free-milling at the surface, it is generally changed into sulfides as depth is gained.
Mineralogical siting and distribution of gold in quartz
