| titleOfInvention | A kind of method of nickel, cadmium purification and recover in solid dangerous waste |
| abstract | The invention discloses the method for nickel in a kind of solid dangerous waste, cadmium purification and recover. Method of the present invention is higher for nickel, cadmium content in nickeliferous, cadmium heavy metal dangerous waste disposal process and containing a small amount of magnesium, calcium, the nickelous carbonate of iron, cadmium carbonate semi-finished product, by carbon containing reducer to the reduction of this semi-finished product, then through acidleach, make in system cadmium oxide dissolve and metallic nickel is insoluble by controlled condition, thereby realize nickel, cadmium separation, isolated metallic nickel is melted into nickel ingot product through 1600 DEG C, and grade is more than 99%; The Cd that dissolving obtains 2+ Solution enters workshop flow process sodium carbonate and is precipitated, and can obtain CdCO 3 Product, its purity is higher than 98%. Method of the present invention has greatly reduced energy consumption and environmental pollution, and flow process is short, condition is easy to control; Material contained in raw material does not need special purification, has reduced process flow and can obtain the product that purity is higher; The selection of reducing agent is convenient, and in conjunction with producing, cost is low. |
