Abstract

"PROCESSO PARA A PRODUçãO DE DOLOMITA SINTéTICA" Um processo para produção de dolomita sintética, a partir de dolomita queimada morta em uma etapa de sinterização simples, para a fabricação de tijolos refratários e outros produtos, compreendendo: trituração de uma dolomita brua de baixo grau, para obter uma dolomita triturada; incorporação de aditivos selecionados do grupo consistindo em Fe~ 2~O~ 3~, SiO~ 2~ e Mg (OH)~ 2~, Ca(OH)~ 2~ ou uma sua mistura, para compensar para as deficiências de Fe, Si, Mg e Ca da dolomita em bruto; misturando uniformemente os aditivos com a dolomita triturada para produzir uma mistura; compactando a mistura para produzir briquetes; peneirando as peças de briquete de modo a eliminar partículas finas e materiais de baixa dureza; queimando os briquetes de modo a prover peças compactadas queimadas sinterizadas; e resfriando os briquetes queimados sinterizados para produção de dolomita sintética.
