Description
Excerpt from The Hydro-Metallurgy of Copper
Along period has elapsed - to be measured by centuries - since the Hydro-Metallurgical Treatment of Copper Ores was originated at the Rio Tinto Mines. Several processes have since been evolved, as the result, in large measure, of the investigations of manufacturers of sulphuric acid, who employ iron sulphides containing a low percentage of copper for the production of the acid, and who made it a special study to extract the residual copper from the burnt pyrites and cinders. The successful solution of that problem led to the adaptation of various leaching processes at a few low-grade copper mines, where smelting operations would have been too costly for the profitable treatment of the ores.
The application of the various lixiviation processes has had only a limited scope up till now; but it is more than likely that in future more attention will be given to them, owing to the necessity which (it may be expected) will arise for an economical exploitation of the low-grade copper deposits occurring in various parts of the globe. These can be made to pay by leaching - which, when judiciously applied, is cheaper than smelting - and in view of the increasing consumption of copper many of these hitherto undeveloped sources of supply will no doubt be opened up and utilised.
