Publisher's Synopsis
Excerpt from Hydro-Electrolytic Treatment of Copper Ores
The problems of economically treating low-grade copper ores have turned the attention of metallurgists toward such hydro metallurgical problems as are encountered with low - grade sili ceous, oxidized and sulphide ores, and concentrates, especially where water-power is cheap and fuel is' expensive. The treat ment of tailings from concentrates is another promising field for leaching methods, there being no other known possible method for economically extracting their copper contents. The same is. Also true of complex refractory ores which are not amenable to smelting for the recovery of their several metals. And, lastly, there are metallurgists who entertain hopes of discovering a leaching method which will radically change all methods of Copper extraction to something quicker and cheaper than the present smelting methods.
