The results of this study show that, after the first rough separation, the grade of chromite concentrate Cr2O3 is %(13% higher than the grade of raw ore), the productivity of that is %, and the recovery rate of that is %.
Recoveries from tabling procedures were low because of fine liberation sizes of the chromite and ranged from 34 to 76 pect, with products containing from 49 to 53 pct Cr2O3. When tests were run with coarsely ground samples (minus 20 or minus 28 mesh), most losses were in the middling fraction.
Copper Nickel Ore Flotation Process. When process coppersulfide nickel ore, collector and frother will be used in order to better results. A basic principle of coppersulfide nickel ore process is that it is better to let copper assimilate into nickel ore rather than the opposite. For it is easier to recovery cooper from nickel concentrate.
tin powder recovery from chromite ore. Chromium Wikipedia, the free encyclopedia . Chromium is a chemical element which has the symbol Cr and atomic number 24. It is the first element in Group 6.
What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromitebearing rocks are altered by heat or weathering.

Chromium metal is obtained commercially by heating chromite ore in the presence of carbon, aluminum, or silicon, and subsequent purification (ATSDR, 2000). Sodium chromate and dichromate are produced by roasting chromite ore with soda ash and are the primary chromium salts from which most other chromium compounds are derived (ATSDR, 2000).
