Technical Field
The invention relates to a flotation collector, in particular to an ilmenite flotation collector and a preparation method thereof, and belongs to the technical field of mineral flotation collectors.
Background
Ilmenite is an oxide mineral of iron and titanium, and is the main ore from which titanium is extracted. In Panzhihua iron ore in Sichuan China, ilmenite is distributed among magnetite particles or in cracks and forms a large deposit. The chemical composition of ilmenite is dependent on the formation conditions. The efficient selection of increasingly poor and refined ilmenite is a main problem in mineral separation, but the existing collecting agent mainly takes oleic acid and fatty acid as main raw materials, such as an MOS collecting agent, the main component of which is oleic acid and also contains toxic arsenic component, so that environmental pollution is easily caused, and meanwhile, the problems of high cost, equipment corrosion and the like are solved.
Ilmenite, one of the main ores from which titanium metal is refined, is an oxide mineral of titanium and iron. The existing collecting agent mainly comprises oleic acid and soaps thereof, which have active carboxyl functional groups, are high in collecting capacity and wide in application range, can effectively separate useful minerals from gangue, and are excellent ilmenite flotation collecting agents, but the collecting agent also has obvious defects in flotation, such as large using amount of the collecting agent, complex medicament system (such as using sulfuric acid to adjust the pH value in the flotation process and needing diesel oil and the like as activating agents), low selectivity, poor freezing resistance and the like, and some collecting agents contain heavy metals and have large influence on the environment, so that the development of a novel, efficient and environment-friendly collecting agent becomes one of the hot spots in the development of the beneficiation technology.
