| titleOfInvention | A kind of method of the leaching of manganese from manganese-silver ore and silver production manganese sulfate and silver |
| abstract | The invention discloses it is a kind of from manganese-silver ore simultaneously leaching of manganese and silver method, its final products be silver powder and manganese sulfate monohydrate.Comprise the following steps that：1) it is that 0.074mm is more than 80% or thinner by manganese-silver ore ore grinding to granularity；2) certain density sulfuric acid solution is configured, a certain amount of potassium permanganate powder is added, adds manganese-silver ore powder and be sufficiently mixed, finally hydrogenperoxide steam generator is slowly added in solution, filtering obtains filtrate after reaction terminates；3) copper sheet of certain area is added and silver is replaced in filtrate, obtain silver-colored mud；4) silver-colored mud obtains silver powder by dilute nitric acid dissolution, hydrochloric acid precipitation and hydrazine hydrate displacement；5) leaching manganese liquid obtains pure manganese sulfate solution by pre-oxidation, except the step purges such as iron, removing heavy metals and removal of impurities；6) manganese sulfate solution obtains sulfuric acid monohydrate manganese product by evaporation and concentration, crystallization, drying and calcination. |
