The invention discloses a method for jarosite precipitation and deironization by pressure acid leaching of high iron zinc sulphide concentrate in a kettle,prises the following steps: conveying the high iron zinc sulphide concentration and zinc oxide ore in a mixing ratio of 23:1 into an autoclave in the zinc leaching process, controlling the acidity to convert most of iron into a
In one method, zinc concentrate is leached when simple sulfur and other by products are stripped from the surface of the concentrate particles using a mill such as a ball mill. The trivalent iron ions consumed for leaching are regenerated by injecting oxygen into the solution after leaching flowing through the feed pipe. This method can substantially shorten the leaching time.
After gold content is increased by physical and mechanical methods the concentrate is used as feeding material for next steps. Gold concentrates are processed by chemical methods in order to recover up to 99 gold, depending on type and efficiency of the processes. The widely used chemical treatment process is the leaching with cyanide.
