Currently, the iron ore technology that based on the oxidation-reduction reaction of sulfide ore, be widely adopted in the mineral processing plants. Take a copper-zinc ore mine as the example, they attach high importance of mineral ore, develop the chemical reaction process and established a complete production model that has achieved good efficient. According to the application and development situation of iron ore beneficiation technology in China, we know that researchers think highly of the flotation process which without a collector.  In China, the common biometallurgical process needs to incorporate leaching technology, which has higher requirements for leaching process and is divided into two different leaching process types according to the leaching working method, one is direct bioleaching, another is indirect metabolize leaching.  For instance, under acidic conditions, the thiobacillus ferrooxidant and mesophilic bacteria, they have good chemical separate performance, immerse into the sulfide ore, then dissolve the metal components and ionic structures, final separate the metal component from the sulfide ore.
