The optimal regimes of activation of arsenopyrite in alkaline solutions, salt with the addition of pyrolusite and sodium hypochlorite. The optimum concentration of the reactants in aqueous solution, providing maximum possible transferring the sulfur to soluble compounds and the binding of arsenic in the state of difficultly. ER -
