The process of ilmenite concentration by means of flotation

摘要

Abstract the process of ilmenite concentration by means of flotation is a process of ilmenite concentration by means of flotation, tailings from beneficiation processes of any types of ilmenitas mechanic, in which the raw material is ground and deslamada so Obtain a material with a particle size in the range of 0037 mm 0210 mm,Followed by repolpagem of minerals and flotation using a salt of radical hidroxamato as collector aforu00e9tico, mixed with kerosene and water, and methyl isobutyl carbinol as sparkling wine. The flotation, carried out in natural pH, and with only one stage, is very selective in relation to the mineral ilmenite. The collector is used in a quantity that varies from 250 to 1000 grams per tonne of ore.Under these conditions, are flotation concentrates containing up to 50% of TiO2 and enriched in titanium greater than 1,50.
