Abstract: 

The improved concentrations of oxide zinc tailing, is one of the most important issue for mineral processing industry. There are a lot of tailing containing zinc oxide ore were deposited in Iran. The Goshfil mine has considerable amount of tailing containing 7.65% zinc, 3.5% of lead and 13% of iron. Previous research for lead and zinc extraction from oxide and carbonate tailing didn’t have success results. In this research the size effect of zinc minerals on the degree of liberation of zinc carbonate and iron oxide is studied by using ground sample in a microscopic scales. The results indicate that smithsonite mineral is more flexible to grinding than the Iron mineral form in the tailing. smithsonite minerals with size of 90 microns are completely liberated whereas the hydroxide ores need to be finer approximately 65 microns. The results also indicate grinded sample below 90 microns are liberated %(80-100) for smithsonite and %(50-100) for iron oxide minerals. One of the promising applications of test results is for the mineral processing of iron oxide since having the fine particles then the control of flotation is facilitated.
