NICKEL PRODUCTION PROCESS |
摘要 |
metallurgy, possibly nickel production from solution of silicate ore leaching. SUBSTANCE: method provides deposition of matters out of solution of silicate ore leaching at changing pH of solution. Method comprises steps of depositing ferrum, separating ferrum-containing deposit; settling manganese from remained solution by converting it from manganese hydroxide to manganese dioxide; extracting manganese dioxide out of solution; washing it out by means of ammonia solution; mixing solution received after washing out with solution remained after separation of manganese dioxide; depositing nickel from prepared mixture by adding sodium sulfide and ammonia to said mixture. EFFECT: enhanced degree of nickel extraction, lowered cost of nickel production process.
