RCF BARYTES

Barytes is a heavy mineral and is the most common barium-containing mineral and is an important industrial mineral. It is sometimes referred to as heavy spar because of its higher specific gravity. The mineral crystallizes in the orthorhombic system often occurring with a plaity structure. It is commonly found in compact massive form. When pure the mineral is colourless and transparent, but it is rare in this for, more usually being white and opaque and commonly stained yellowish, pink or red by iron. Strontium and calcium sulphates may be included in small amounts; clay and quartz are often present as impurities.

RCF Barytes KW is a heavy mineral occurring most commonly (in commercial deposits) in light-coloured granular or crystalline masses or in nodules. It also occurs in tabular crystals of the orthorhombic system. The crystals are easily cleavable in three directs, two perfect and one imperfect. It is also called tiff, cawk or heavy spar and is the most common ore mineral of barium. The RCF Barytes KK occurs as irregular lenses and pockets of coarsely crystallized and fine-grained massive Barytes in silicified feldsistic schist’s. Certain of the surface material is white and of good quality but where opened the mineral is variable in colour, much of it being pink and stained. Only a limited quantity can therefore be sorted as high grade white material and the bulk would require bleaching. In its pure form it contains 65.7% BaO and 34.3% SO₃.

The main use of this barytes may be divide into three main groups: Ground barytes for various uses, lithopone and barium chemical industries.

It is mainly used as inert mineral filler in paper, rubber, cloth, linoleum, oilcloth, and paint and also as an inert extender. It is especially useful as filler and a surfacing material in playing cards, enameled paper etc, where a highly calendared surface is desired. It is also used as a base for the precipitation of lake colour, in ceramic glazes and enamels and also as inert filler in various products where heavy, crystalline inert filler is desired.
