These days heavy media method is being applied in order to reach the concentration of elements such as Lead and Zinc in Calcimin (public Co.), However this very process is being done by a lot of waste on the process of the separation of Lead and Zinc ores and not in a desired manner. The purpose of this study is to optimize the influential parameters in the process of separation and concentration of oxidized ore of Lead and Zinc silicate in Angouran Mine with heavy liquid experiments, and conclusions and suggestions for heavy media method. Selecting the samples have been done through atomic absorption analyze, XRD analysis, XRF analysis along with microscopic analysis via applying thin and polished sections. According to the results obtained from sampling the grades of Lead, Zinc and Calcium in the feed sample have been 1.98%, 18.99% and 10.34% respectively. Lead and Zinc minerals were Cerusite, Smithsonite and Hemimorphite and Calcite was considered as gangue mineral. Liquid density and particle size were investigated in order to do the heavy liquid experiments. The heavy liquid experiments have been done by applying Diiodomethane heavy liquid carried out. For size fractions -15000+6350, -6350+4000, -4000+2000,-2000+1180,-1180+600 micron, experiments each with three levels of density (2.8, 3 and 3.32 g/cm3). According to the results obtained the heavy liquid with density of 3 g/cm3 concentration of precious materials are the most appropriate in terms of density. The most appropriate particle size is the range of -4000+1180 microns which has been certified by the microscopic studies. At the level of -4000+1180 microns the grade of lead and zinc in the floated materials have been 3.32% and 40.2% which compared to gangue alloy have been doubled. The grade of calcium has been 2.21% which is reduced.
