Borax is a white, odorless, powdered substance. Load in Covered Hoppers. The glass and porcelain industries are the major consumers of boras and boric acid, consuming over 50% of the total production. The boric oxide behaves as a network - former in glass and ancillary industries and is a powerful flux. It is an essential component of heat-resisting boro-silicate glass, glass fibres, industrial, optical and other glass. In glass, enamels and glazes it controls thermal expansion, improves durability, assists the melting processes and is also a component of inorganic colours and decorations.
Mining
The mining of borates is dependent upon the mode of formation. Kramer deposits in California are worked both by open pit and underground method. The borate beds have been found there underlying between 40 to 300 metres from the surface. The deposits consist of thick beds of kernite and borax. The ulexite deposits in Turkey are mined by driving parallel adits. The Turkish ore is mainly ulexite mixed with colemanite, and priceite (Ca4B10O19.7H2O). The minerals are mined together and brought to the surface for further processing and refining. The borax salts, as found in the brine solution of the Searles lake, California, are pumped up, processes and refined from the mixed solution by the well-known fractional crystallization process commonly known as 'Troma process'.
