Problems solved by technology
At present, the most widely used rutile collectors are fatty acid agents. Although these agents have the advantages of strong collection capacity, their selectivity is low, resulting in high impurity content and low grade in the concentrate, which affects rutile resources. efficient use of

The invention provides a collecting agent composition for rutile ore flotation. The collecting agent composition for rutile ore flotation comprises, by weight, 45-55 parts of a drug A, 10-25 parts of a drug B, 15-25 parts of sodium oleate and 5-10 parts of kerosene. The collecting agent composition provided by the invention is high in selectivity and good in collecting capacity and can effectively reduce the impurity content of rutile concentrate, the grade of the rutile concentrate can be improved by 10% or over, and the recovery rate of the rutile concentrate can be improved by 4% or over.
Description
technical field [0001] The invention relates to the technical field of mineral processing, in particular to a collector composition for flotation of rutile ore. Background technique [0002] High-grade rutile is the best raw material for producing rutile titanium dioxide and one of the necessary raw materials for high-grade welding electrodes. It is also a high-quality raw material for producing titanium tetrachloride, titanium metal, titanium alloy and enamel products. With the rapid development of titanium industry , the demand for high-grade rutile is increasing day by day. However, my country's primary rutile ore has low grade, fine particle size, and complex composition. These mineralogical characteristics have led to no breakthrough in the beneficiation process of primary rutile, so we have to rely on importing foreign rutile concentrates or using high-cost artificial rutile to meet my country's high-end rutile. The development requirements of the titanium industry. T...
