砷铅锌烧渣中金的氰化浸出研究

Study On Gold Cyanidation Leaching From Roasted Residue Containing Arsenic,Lead and Zinc

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。

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.
