Chromite is the most important ore of chromium from which it derives its name. Chromium is an important metal and has a wide range of industrial uses. Chromite forms in deep ultramafic magmas and is one of the first minerals to crystallize.

The principle chromium ore, chromite, is heat resistant in the same way. It is this property, along with its chemical stability, that makes chromium useful as a refractory material. Refractory materials are used as insulation to line the inside of blast furnaces and crucibles used in metal manufacturing, especially in refining metals and making ...

A chemical analysis that determines the proportion of metallic (Cu, Pb Zn, Au, Ag, etc.) or non metallic (Fl, S, P, etc.) elements in a sample is commonly referred to as an assay. A wide variety of geological materials can be chemically analyzed: these include water, vegetation, soil, sediment and rock.

what is the ore of chromium Understanding Iron Ores and Mining of Iron Ore | Understanding Iron Ores and Mining of Iron Ore. Iron (Fe) is an abundant and a widely distributed element in the in the crust of the earth, constituting on an average ranging from 2 % to 3 % in sedimentary rocks to % in basalt and gabbro.

Chromium was discovered as an element after it came to the attention of the Western world in the red crystalline mineral crocoite (lead(II) chromate), discovered in 1761 and initially used as a pigment. Nearly all chromium is commercially extracted from the single commercially viable ore chromite, which is iron chromium oxide (FeCr 2 O 4). Chromite is now the principal source of chromium for pigments.

Basic rock refers to an igneous rock with a low percentage of silica and a high percentage of pyroxene, hornblende, and labradorite. Bauxite Bauxite is a sedimentary rock group of various aluminium oxides, a principal ore of aluminium, found in France and Jamaica. Bauxite was named after the place where it was first found, Les Baux in France.

Chromium increases the case depth of the carburized steels while nickel decreases it (Figure 33(a)). Chromium (as Cr 3 C) and nickel refine the austenite grain size of the carburized case but nickel is more effective than chromium in inhibiting the austenite grain growth (Figure 33(b)).
