Arsenic and sulfur elimination from cobaltiferous ores |
| abstract |
A method for removing sulfur and arsenic from cobaltiferous ores and recovering an enriched cobalt product is described. The procedure involves the steps of n (a) oxidizing said ore at a temperature of at least about 700° C. to reduce the sulfur content of the ore to the desired level, n (b) heating said oxidized ore with a reducing agent at a temperature of at least about 700° C. to remove arsenic from the ore, and n (c) recovering an enriched cobalt containing solid as the product of the process. |
