Zinc sulphide concentrate leaching method

The present invention discloses a zinc sulphide concentrate leaching process, the method comprising: zinc sulphide concentrate leaching for a period of oxygen pressure; After the period of oxygen pressure leaching leachate treatment indium sink, in order to obtain indium indium liquid slag and Shen ; Shen indium after mixing with a neutralizing agent and a liquid acid solution; the pH of the first mixture is from 1.5 to 2.5, temperature of 90 ° C to the boiling point, and maintained 0.5-6 hours; and the mixture was filtered a second process in order to obtain iron products and iron sink after fluid. This method is simple, low cost, easy factory, and recovering a high iron content in the iron-containing product obtained in the zinc content is low, and further the iron product can be used directly as iron ore, iron and the heavy liquid zinc can be used for fine mine production.
