Verifying the Most Suitable Soluble to Repulsing ReO-4 and Mo0 24 Ions in Selective Separation Re from Active Carbon

The most important raw material for Re extraction is molybdenite. In molybdenite smelting for molybdenum oxide production, Re oxide will be deposited as dust on filters and cyclones. According to low content of Re in this dust, extraction of Re should be done by solution, exchange ionic bider and active carbon methods. In active carbon method carbon active surface will absorb the Re ions from leaching solution. Molybdenite and ReO-4 ions then will be separated. In the first step of depletion it is necessary to deplete the maximum content of Mo ions and the minimums content of Re and in second step solution should deplete. The max content of Re ions. In this research HC1, NaOH, CaC03 , NaCl were used for molybdenum deplete and Ethanol, Acetone, Proparol any isopropanol were used tor Re. depletion and effects of solution concentration in depletion were be studied.
