insensitivity to flow variations, insensitivity to temperature variations, small plant volume, virtually no water loss, high total solids content of separated sludge, very high degree of separation even for very small particles, simple operation, High process capacity, low operating cost and fast payback of investments are the main reasons make flotation method as a most economical mineral processing method. In this regard, ILZIMCC (IRAN lead and zinc industries and mines cooperative company) decided to use concentration method to produce lead and zinc concentrate appropriate to use in subcontractor companies to reduce operating costs of leaching process to eliminate distracting elements.

ILZIMCC has stablished to process 250,000 ton material per year, GSZ’s team carried out a complete range of primary study like mineralogical study, and flotation tests to determine ability of mineral to recovery lead and zinc sulfide and oxide ore by cumulative or diffractive methods in lab and pilot scale. All of the feasibility studies by new methods and low equipment cost with all of simulation andStrength Analysis and calculation was a big advantage of process to make responsibility to achieve optimum single-point. Designed ball mill special shape for this company has a beneficiation to simplify grinding control with high insurance level.
