Acid Leaching – Copper Ore Treatment Method
The treatment of copper ores, both oxides and sulfides by means of flotation, hydrometallurgy or other processes has been well established for many years. Flotation has been applied generally to the treatment of sulfide ores, both in small and large scale operations. Hydrometallurgical methods alone or in combination with flotation have mainly been applied to […]
Method of Precipitating Copper
During the last few years we have been doing considerable experimenting on methods of precipitating copper. The first patent on precipitating from sulphate solutions by heating with SO2 under pressure was taken out by us (U. S. Pat. 723,949). This reaction, CuSO4 + SO2 + 2H2O = Cu + 2H2SO4, is interesting, but there are […]
Leaching Copper: Iron form Electrolyte
The solvent we would use; how we would precipitate the copper from the solution, and what we would do with the iron in the electrolyte. Without going into the details of the reasons, we decided that sulphuric acid would be the most satisfactory solvent and that we would recover the copper from the solutions by […]
