The extraction process is as follows: 1. Preparation of active zinc oxide: oxidized ore - pulverization - extractant leaching - filtration - impurity removal - decomposition and recovery of extractant - drying - roasting - pulverization - active zinc oxide finished product; 2. Advanced zinc powder: Oxidized ore - crushing - extractant leaching - filtration - decomposition and recovery of extractant - drying - high-grade zinc fine powder; the specific process is as follows: the mineral powder and the desired extraction The agent is added to the stirring tank, and after being fully stirred, it is input into the reaction tank, and is fully stirred by a stirrer provided on the reaction tank, and the test is performed once every 1 hour, and the mixture is continuously stirred for 3 hours. After the extraction rate reaches 90%, the reaction is formed. The metal solution is input into the liquid storage tank, and then the metal solution is self-flowed from the liquid storage tank into the decomposition tank to be heated to boiling. When the metal solution becomes colorless and transparent, the heating is stopped, the metal solution is filtered, and dried. The metal oxide is obtained by electrolysis to obtain the metal.

The process of extracting zinc , copper , nickel and cobalt from the smelting ore by water smelting method, adding the mineral powder and the required extracting agent into the stirring tank, and after fully stirring, inputting into the reaction tank, which is characterized by mixing ammonia water with ammonium hydrogencarbonate. The solution is used as an extractant. The ratio of ammonia to ammonium bicarbonate is determined according to the concentration of ammonia water. The ratio of 10% ammonia water is 20:1, 15% ammonia water, the ratio is 15:1, 20% ammonia water, the ratio is 10:1, the ore is pulverized to a particle size less than 1mm slag, depending on the amount of the extractant amount of zinc or copper or cobalt or nickel ore is determined, for the metal of the slag content of less than 5%, each extraction with t 1t, the metal content increased by 1 to 5%, the amount of extractant increased by 0.5t.
