| Abstract: | A novel process with two-stage surfuric acid counter flow digestion-ferric and calcium carbonate arsenic removal-low temperature catalytic hydrogen reduction and disproportionation of copper in acetonitrile solution was studied for arsenical cupric oxide in this work.In this process, arsenic was effectively separated, to minimize pollution to the environ ment, and copper was recovered in the form of well dispersed copper powders with an average particle size of 50 microns. |
