Metallurgical Test Work: Gold Processing Options, Physical ...

2016-1-1  The recovery of gold from heaps or dumps is often seen as a specialty area of gold metallurgy or, at the least, gold processing (Van Zyl et al., 1988). A requirement to be able to scale up from laboratory tests to field application has seen the need to develop specific procedures and techniques, in order to facilitate this and minimize risk.

Metallurgical testwork: Gold processing options,

2005-1-1  1. Background. For the past 100 years the key element in the processing of gold ore has been the cyanidation process. Over the years steady improvements have occurred in equipment design; milling has evolved from stamp mills, through tube mills and ball mills to the large semi-autogenous grinding (SAG) and fullyautogenous grinding (FAG) circuits in modern gold plants.
