【摘要】 砷铅锌烧渣与渗透剂一起磨至100%通过-200目后置于搅拌槽中,在选择条件下,用碳浆工艺氰化浸出,可使烧渣中金的含量从7.3g/t下降到0.5~1g/t,具有较好的经济效益。更多还原

【Abstract】 The roasted residues containing arsenic,lead and zinc were ground with seepage reagent to-200 mesh(100% through rate), then sent to a stirring tank.Under the selected condition,the residue was leached with the carbon thick liquid craft cyaniding.The gold content in the residue decreased from 7.3g/t to 0.5~1g/t.The apply of this technique could obtain good economic efficiency.更多还原
