Collector for rutile flotation and using method

Abstract

The invention discloses a collector for rutile flotation. A compound of salicylhydroxamic acid, linolenic acid and sodium dodecylsulphate is adopted as the collector. The collector comprises, by mass10-80% of the salicylhydroxamic acid, 10-80% of the linolenic acid and 10-40% of the sodium dodecylsulphate. According to a combined drug, the collecting capability and selectivity on rutile are improved through the synergistic action among drugs; compared with a single rutile collector, the rutile collector has the advantages of being less in drug consumption, less in price, soluble under room temperature, free of toxin, efficient and environmental friendly, and the rutile collector has significant meaning in improving the recycling of titanium resources.

Description

technical field

[0001] The invention relates to a collector used for rutile flotation and a usage method, belonging to the field of mineral processing chemicals. Background technique

[0002] Flotation is an effective method for sorting rutile; most foreign rutile resources are seaside placer, which has coarse particle size and high dissociation degree, and generally does not need grinding and flotation operations, so there are few researches on rutile flotation process abroad. China's rutile reserves are relatively insufficient, and there are relatively more rock-type resources and relatively less placer-type resources. In particular, coarse-grained rutile resources with a high recovery rate of ore dressing are scarcer, and domestic rutile ore rutiles are embedded with fine grain size and veins. The stone symbiosis is closely related, and it is difficult to reselect tailings and sorting. Therefore, the key factor in the development and utilization of rutile resources in my c...
