Реферат
The kinetic of heap leaching process of copper-zinc ore in conditions of using subdump water and products of its electrolysis has been researched. The possibility of using acid subdump water instead of sulphuric acid solutions as the agent for leaching copper-zinc ores with sophisticated material composition has been established. It has been also used for intensification of leaching process of Cu—Zn ores via electrochemical processing of subdump water with previously addition of 20 g/l of NaCl salt, increased speed of copper and zinc dissolution in productive solution by 2.8–6 times. The optimal parameters of electrochemical processing of subdump water (current density on electrodes is 250 A/m2, electrolysis duration is 10 min), provided 1.5 g/l active chloride concentration have been developed. It has been allowed to attain copper and zinc concentration in productive solution to 333 and 2214 mg/l respectively. Brench-top module device, which allow to research leaching process of valuable components on the ore with wide fineness diapason in continuous conditions has been produced.
Ключевые слова Leaching, copper-zinc ores, subdump water, technology of water preparing, electrochemical processing, speed of dissolution, productive solution.
