Gold-Copper Ores

Copper can form four complexes with up to four cyanide ligands. The distribution of the cyano complexes depends on conditions such as cyanide concentration and pH, as shown in Figure 43.1.The distribution of the various species as a function of pH and sodium cyanide concentration indicates that high pH and free-cyanide conditions …

Gold processing

Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …
