Method for recovering valuable metals from electrolytic manganese sulfide slag and electrolytic manganese anode slime

The invention provides a method for recovering valuable metals from electrolytic manganese sulfide residues and electrolytic manganese anode slime, which comprises the following steps: carrying out dry ball milling on the electrolytic manganese sulfide residues and the electrolytic manganese anode slime to obtain a ball-milled mixture; the ball-milled mixture is subjected to sulfuric acid leaching, and acid leaching residues and acid leaching liquid are obtained; adding manganese fluoride into the acid leaching solution, and reacting to obtain calcium magnesium slag and a purified solution; adding an extraction agent formed by mixing C272 and sulfonated kerosene into the purified liquid for extraction to obtain a zinc extraction liquid and a zinc raffinate; sulfuric acid is added into the zinc extraction liquid for reverse extraction, and a zinc sulfate solution is obtained; adding an extracting agent formed by mixing P507 and sulfonated kerosene into the zinc raffinate for co-extraction to obtain a manganese
