The seaside placer is a very important deposit in the mineral resources of Hainan and Guangxi in China, and the deposit is accompanied by zirconite, monazite and the like with extremely large reserves besides abundant ilmenite reserves. Foreign sources of this type are also abundant elsewhere, typically in australia, malaysia, the united states, south africa, brazil, india, mozzarex, etc.
In the process of magnetic separation of ilmenite, because monazite has certain weak magnetism, a small amount of monazite is often contained in ilmenite concentrate, and because monazite contains P, the content of P required in the ilmenite concentrate is below 0.1%, the quality of fine ilmenite is reduced, and because monazite is reduced, the economic benefit of production enterprises is also reduced. The removal of monazite from ilmenite is therefore one of the essential ways to increase efficiency. Therefore, the method has important theoretical significance and practical application value for strengthening the research on the beneficiation technology of the ilmenite resources.
At present, few documents are reported on the ore dressing process of ilmenite floatation monazite, and a sodium oleate floatation method is mainly adopted and is carried out under strong acid or strong alkali. Because of the influence of the current environmental protection measures, strong acid and strong alkali are not suitable for the recovery of valuable metals such as monazite and the like at present. The Yangtong flotation operation is carried out on zirconite and monazite in ilmenite in a certain seashore placer in Hainan province. Under the condition that the raw ore contains TREO 6.12% and the pH value is more than 12, the monazite rough concentrate with TREO 9.12% and the recovery rate of 85.71% is obtained by adding the sodium oleate collecting agent.
