Abstract
The present invention discloses a process for the production of calcium borate from boric acid, said process comprising: reacting boric acid obtained from any source with a calcium compound, preferably with calcium hydroxide, in an aqueous media, to obtain a solid calcium borate suspension which is subsequently separated from residual solution. Preferably, boric acid is prepared from minerals containing borate salts, particularly colemanite and haulite; wherein ground or crushed minerals are reacted with sulphuric acid in an aqueous media at a high temperature for producing a solid pulp, mainly including gypsum and clay, in a liquor; solids are eliminated from the liquor and boric acid is crystallized.
