borax processing production

  • Overview Borax Pentahydrate

    Manufacturing Process. The production processes of borax pentahydrate are similar to borax decahydrate. Borax obtained from lake brines, tincal, and colemanite is separated from the constituent salts. The hot liquor obtained is consisted of borate and potassium salt (KCl). To remove the potassium salt, the insoluble solid particles are filtered

    OverviewChemistryEtymologyNatural sourcesUsesToxicitySee alsoCited sources

    Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is a compound with formula Na 2H 4B 4O 9•nH 2O or, more precisely, [Na•(H 2O) m] 2 [B 4O 5(OH) 4]. The formula is often improperly written as Na 2B 4O 7•(n+2)H 2O, reflecting an older incorrect understanding of the anion's molecular structure. The name may refer to any of a number of closely related boron-containing mineral or chemical compounds that differ in their water of crystallizationconten
