Abstract
The application relates to a titanium middling physical-chemical coupling reinforced upgrading method, and belongs to the technical field of titanium ore dressing. Manganese-containing minerals are mixed with titanium middlings for mixed grinding to obtain titanium middling slurry; a binary mixed collector is prepared: first, unsaturated fatty acid collectors and hydroxamic acid collectors are uniformly mixed according to a mass ratio of 10:1-20:1, and a water solution is added to prepare the binary mixed collector; desulfurization is carried out to obtain sulfur concentrate and desulfurization tailings; intensified flotation is carried out: the desulfurization tailings are coarsely selected to obtain coarse concentrate and coarse tailings; the coarse concentrate is subjected to 1-2 times of concentration to obtain titanium concentrate and middlings; the coarse tailings are subjected to 2-3 times of scavenging to obtain middlings and tailings; the middlings in the selection process are returned to the previous operation to form a closed-circuit flotation system. The method can effectively further prepare high-quality titanium concentrate from titanium middlings, and ensures a high recovery rate.
