| titleOfInvention | Cupel litharge reprocessing method |
| abstract | FIELD: nonferrous metallurgy. SUBSTANCE: method involves grinding and treating cupel litharge by nitric acid; separating obtained lead nitrate solution from solids; precipitating lead sulfate from solution; depulping lead sulfate in water and continuously pouring with sodium hydroxide solution at pH value of 10.0-10.6; separating obtained tribasic lead sulfate from mother solution, washing and drying. Ready product may be used as polyvinylchloride plasticizer stabilizer in plastic material production. EFFECT: increased efficiency and enhanced reliability in operation. 2 tbl |
