Abstract
The invention discloses a composite beneficiation inhibitor used for copper-arsenic separating flotation. A hydrophilic oxide film can be formed on the surface of a mineral containing arsenic and copper to selectively separate a mineral which does not contain the arsenic and the copper from the mineral containing the arsenic and the copper. The composite beneficiation inhibitor is composed of, by weight, 75-95 parts of calcium hypochlorite, 8-25 parts of sodium humate and 8-17 parts of sodium hexametaphosphate. The composite beneficiation inhibitor is prepared sequentially through the steps of mixing, grinding and remixing.
