Copper Ore

Copper complexes that can be present in cyanide liquors include Cu (CN) 2 −, Cu (CN) 3 2 −, and Cu (CN) 4 3 − with the proportions dependent on the pH, copper concentration, and free cyanide concentration. The main issue facing the process engineer is the fact that minimization of cyanide consumption is favored by the formation of species with a low copper:cyanide mole ratio, e.g., Cu ...

9 Ore Deposits and Economic Minerals – Mineralogy

Many different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of the rest of this chapter.
