Diagnostic Leaching for Refractory Gold Ores SRK

A diagnostic leach test can be very useful to qualitatively assess how gold occurs within the ore and the extent to which it may be refractory. Several different permutations of diagnostic leach tests depend on specific objectives, but they generally involve the sequential leaching of a gold ore sample with progressively stro nger reagents, producing a qualitative assessment of the gold deportment within

Properties of Copper Ores The University of Arizona

Properties of Copper Ores The Problem Minerals from which copper can be extracted to make money are called copper ores. There are several copper ores, but they all fall into two main categories oxide ores and sulfide ores. Oxide ores contain oxygen. Sulfide ores contain sulfur. Azurite, malachite, and chrysocolla are a few examples of oxides ores.
