Separation of arsenic minerals from high arsenic grade copper-containing materials |
| abstract |
PROBLEM TO BE SOLVED: To provide a method for obtaining a low-arsenic grade copper concentrate by separating an arsenic mineral from a copper-containing material containing arsenic such as copper ore and copper concentrate. A floatation agent containing a suppressor, a foaming agent, and a collection agent is added to a slurry composed of a copper-containing material containing arsenic, and air is blown into the slurry to float the copper concentrate. A method for separating arsenic minerals from a copper-containing material by performing beneficiation, wherein sodium thiosulfate is used as the inhibitor. This sodium thiosulfate is preferably added in an amount of 10 kg or more and 200 kg or less in terms of pentahydrate with respect to 1 t of the copper-containing material to be subjected to flotation. Moreover, it is preferable that the oxidation-reduction potential of the slurry at the time of flotation is −10 mV or more and 50 mV or less using a silver-silver chloride electrode as a reference electrode.
