Abstract. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, in the form of kaolinitic clay, and also to increase the alumina content. Additionally, reduction in iron content, particularly in the form of goethite, and reduction of organic carbon can also increase the value of the bauxite product.

Idiomorphic chromite is the only ore mineral appearing in economic quantities. The average content of the ore is 26% Cr 2 O 3 and the Cr/Fe ratio is 1.55. The Kemi chromium mine is an open-pit mine with a waste rock to ore ratio of 5.5:1. At Kemi, the ore from the mine contains 11% iron and 25.5% Cr 2 O 3.

Beneficiation is ... and chemical industries as chrome chemicals. A substantial portion of chromite produced is exported. Specifications for different uses are given below in Table 1 [3] .
The mostly utilized industrial minerals are mainly: asbestos, barite, bauxite, bentonite, borax and borates, beryllium minerals, celestite, chromite, diatomite, dolomite, feldsfar, …
Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other. No chemical changes to the minerals are made at this point in the mining process. The phosphate ore, or "matrix" as it is called locally, contains three different mineral groups which have to be separated from each other.
chrome), refractory, and chemical, are the Cr2O3 content, Cr:Fe mass ratio, and friable/massive nature of the ore. The total chromite deposits in the world and the beneficiation practices have been described by various authors [1−2]. The estimated reserve of chromite ores in India is approximately
The most common chemical reagent used to enhance the removal of calcium and magnesium hydroxides is ammonium chloride. Chemical dissolution of …
3. Beneficiation of lithium ores. The major techniques used in the beneficiation of lithium minerals are shown in a generalised flowsheet in Fig. 4, and include gravity separation (DMS), magnetic separation, and froth flotation. Sorting is also being recognised as a potential method in recent years.
