Abstract

Compared with the prior art, the system for comprehensively recovering the precious metal from the high-sulfur nickel anode slime comprises rotary roasting equipment used for roasting the high-sulfur nickel anode slime; the flue gas treatment system is connected with the rotary roasting equipment and is used for treating desulfurized flue gas; the sodium sulfite preparation device is connected with the flue gas treatment system; the desulfurization residue acid leaching system is connected with the roasted product; the noble metal slag storage chamber is connected with the sodium sulfite preparation device and the desulfurization slag acid leaching system; the gold leaching system is connected with the precious metal slag storage chamber; the palladium-platinum adsorption system is connected with the gold leaching system; the analysis system is connected with the palladium-platinum adsorption system; and the first refining system is connected with the analysis system. According to the technical scheme, compared with the prior art, the production process is short, operability is high, and the recovery rate of precious metal can be increased. The invention further relates to a method for comprehensively recovering the precious metal from the high-sulfur nickel anode slime, and the method also has the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of precious metal recovery, and more specifically, relates to a system for comprehensively recovering precious metal from high-sulfur nickel anode slime. The present application also relates to a method for comprehensively recovering precious metal from high-sulfur nickel anode slime. Background technique [0002] The high-sulfur nickel anode slime produced by the electrolytic nickel system of the nickel smelter can reach tens of thousands of tons per year. The anode slime specifically involves: nickel 0.65%, copper 0.53%, sulfur 88.84%, iron 0.4%, arsenic 0.0l%, Cadmium 0.0007%, gold 38.94g / t, silver 8.6g / t, platinum 50.1g / t, palladium 45.07g / t, rich in precious metals, relatively high, sulfur content is quite high, traditional treatment heat filtration method desulfurization to sulfur, desulfurization residue Sulfur content also reaches more than 40%, or adopt gypsum method, ionic liquid desulfur...
