| titleOfInvention | The technique of two ore deposit integrated process process red soil nickel ores and pyrolusite |
| abstract | The present invention relates to the technique of a kind of two ore deposit integrated process process red soil nickel ores and pyrolusite, comprise the following steps: after being mixed with coal by red soil nickel ore, roasting obtains nickeliferous, the ferrous powder of cobalt oxidation; Nickeliferous, the ferrous powder of cobalt oxidation is leached with the vitriol oil; After filtration, add ammonium sulfate to solution, control Hn 2 sOn 4 concentration, adds pyrolusite, by Fen 2+ be oxidized to Fen 3+ , Mnn 4+ be reduced into Mnn 2+ , after filtration, obtain containing MnSOn 4 solution and ammonium jarosite precipitation; Vulcanizing agent is added containing MnSOn 4 solution in, produce nickelous sulfide and cobaltous sulfide precipitation, will obtain after precipitation drying mixing nickelous sulfide, cobaltous sulfide powder; By the ammonium jarosite precipitation roasting obtained, dry after washing, obtain crude iron red.This technique can extract the valuable metal elements such as nickel, cobalt, iron, manganese from two ore deposits, and compared to processing red soil nickel ore and pyrolusite respectively, this technique has saved production cost, improves production efficiency. |
