Abstract
"PROCESSO PARA NEUTRALIZAçãO DE LODO VERMELHO E DO LICOR USADO NO PROCESSO BAYER, DEJETOS DA INDúSTRIA DO ALUMìNIO". A invenção se refere a um processo para neutralizar o licor usado no processo Bayer, uma solução cáustica que forma parte do lodo vermelho, considerado como dejeto da indústria do alumínio. Este tratamento consiste na adição ao licor Bayer purificado, de agentes de neutralização, tais como microsílica, cinzas de combustão de carbono, caulim, argilas, bauxita, silicato de sódio ou outro composto que contenha caulinita, haloisita, sílica ultrafina ou outros minerais silico-aluminosos reativos em meio básico."Process for neutralizing red sludge and liqueur used in the Bayer process, aluminum industry waste". The invention relates to a process for neutralizing the liquor used in the Bayer process, a caustic solution that forms part of the red sludge, considered as waste from the aluminum industry. This treatment consists in the addition to the purified Bayer liquor of neutralizing agents such as microsilica, carbon combustion ashes, kaolin, clays, bauxite, sodium silicate or other compound containing kaolinite, haloisite, ultrafine silica or other silico-minerals. reactive alumina in basic medium.
