Characterization of dolomite, pyrite and chalcopyrite,

We studied the dolomite CaMg(CO3)2, pyrite FeS2 and the chalcopyrite CuFeS2 mineral rocks of Pakistan, using electronic probe micro analyzer (EPMA) of scanning electron microscope (SEM) with energy dispersive X-ray spectrum (EDS) analyzer. We observed in dolomite two phases perhaps due to crystallization in the matrix, due to calcite CaCO3 and quartz SiO2.Separation Process of Chalcopyrite, Galenite, Sphalerite,,Separation Process of Chalcopyrite, Galenite, Sphalerite and Pyrite. 1. The Separation of Chalcopyrite and Pyrite Method It depends on the ore property, including the following two methods: 1.1 Preferential Flotation: This method is suitable for dense lump ores. Under relatively coarse fineness, chalcopyrite and pyrite can be fully dissociated,Galvanic Effect of Pyrite on Chalcopyrite Leaching in,,Jul 18, 2013· Chalcopyrite concentrate and mixtures of pyrite/chalcopyrite were leached in H2SO4-NaCl-O2 solutions to assess the effect of pyrite on the chalcopyrite dissolution rate in this media. The results showed that the addition of pyrite increases the dissolution rate of chalcopyrite at short leaching times but the catalytic effect of pyrite decreases as the reaction progresses.

Establishing thE ProcEss MinEralogy of gold orEs

In gold ores, pyrite and arsenopyrite often occur in three morphological types: coarse, porous (blastic) and fine-grained. Framboidal and microcrystalline pyrite are also observed in some gold deposits. Generally, the order of concentration of gold in pyrite and arsenopyrite is: fine-grained>porous>coarse-grained (Figures 8 & 9). In someRcovery of gold in pyritic ores - Mine Engineer.Com,The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).,
