Description
Summary:The combined processing variant of the Udokan sulfide copper concentrate involving low-temperature roasting with potassium chloride and the subsequent two-stage leaching of the obtained sinter consisting of copper chloride and potassium salts is described. At the first stage, water-soluble salts are leached (potassium sulfate and chloride) with water and, at the second stage, copper chloride is leached with sulfuric acid. The final products are copper vitriol and potassium fertilizer. The parameters of the main stages of the suggested technology are optimized.
