| titleOfInvention | A kind of preparation method of high-purity zinc sulphide |
| abstract | The invention discloses a kind of preparation method of high-purity zinc sulphide. Comprise following step: in zinc solution, add appropriate 1-Nitroso-2-naphthol-3,6-sodium disulfonate, the foreign metal ion in zinc solution reacts with it and generates coordination ion; Then, by solution of zinc sulfate after treatment, by D302 anion exchange resin, coordination ion is combined with D302 anion exchange resin to be trapped in and in ion exchange column, is obtained high-purity sulphuric acid zinc solution; Finally, in high-purity sulphuric acid zinc solution, add thioacetamide and softex kw, generate high-purity superfine zinc sulfide. The invention has the beneficial effects as follows: 1, the zinc sulphide purity of preparation is high; 2, the zinc sulfate rate of recovery is high; 3, raw material sources is extensive, ion exchange resin is reusable, and production cost is low; 4, zns particle is even, granularity is little; 5, production technology is simple, and energy consumption is low. |
