(PDF) Evaluation of gold ore properties and their impact on grinding

Purpose. The purpose of this paper is to evaluate the efficiency of grinding operations in terms of how mechanical properties (e.g., strength properties and ore texture) affect the Bond Work Index.Specifically, the grinding behaviour of two different mill feeds (model quartz and iron ore) together with solid loadings (50, 57, and 67 wt% solids) were correlated against measured acoustic signals.A typical flowsheet for processing refractory gold ore (Sulphidic Gold

The above pre-treatment stages can be changed based on ore mineralogy. For a complex Au–Ag ore, direct cyanide leaching resulted in only about 47% and 19% extraction of gold and silver even after very fine grinding at <38 µm.Diagnostic leaching was carried out to assess the nature of refractoriness [29].Depending on the results of the diagnostic test Figure 6.6 illustrates a simplified study procedure for gold deportment used at JZMIN, including characterization of microscopic gold, submicroscopic gold, and surface gold.
