There are many kinds of ores, in addition to metal ores and non-metallic ores, metal ores are also divided into natural ores, sulfide ores, oxidized ores and mixed ores according to the chemical state of the metal. Minerals where useful minerals are natural elements are called natural ores, such as gold, silver, platinum, elemental sulfur, etc. The characteristic of sulfide ores is that the useful minerals are sulfide, such as chalcopyrite (CuFeS2), galena (PbS), etc. Useful minerals in oxidized ores are oxides, such as magnetite (Fe3O4), hematite (Fe2O3) and so on. There are both sulfide and oxidized minerals in the mixed ore.

How to produce iron fine powder from Tailings (pyrite)
Recently got some information about iron fine powder refining, but there are cross-industry, in our downstream crushing equipment how many things have exceeded the scope of knowledge of the small editor. But consult the relevant materials and ask the engineers in the use of tailings, steel slag and other refining iron fine powder, titanium powder knowledge to share with you the traditional analysis, for the metal mine is very mysterious and very need the public in the world.

What kind of moisture meter does "iron fine powder" need
Iron fine powder beneficiation process: In the steel sludge wet magnetic separation iron fine powder process method is to put the steel sludge into the slurry tank, the first water immersion, and then impact the steel sludge with high pressure water and add the appropriate water to make the steel mud to the rule fineness, steel mud through the slurry pool in the screen is transported to the magnetic separator material box, at the moment magnetic separator iron fine powder and tailings, The fine iron slurry flows into the dewatering tank for dehydration and storage, and the tailings slurry is discharged into the tailings pit. This method can completely recover the iron fine powder in the steelmaking sludge, so as to achieve the maximum utilization of resources.
