Abstract

The invention provides a beneficiation process for sorting monazite and rutile by utilizing a composite collecting agent and an application thereof. The beneficiation process comprises the following steps: (1) mixing 10-15 parts by weight of tall oil, 25-35 parts by weight of oxidized paraffin soap, 40-50 parts by weight of palm oil and 10-15 parts by weight of sodium fatty acid methyl ester sulfonate, and carrying out microwave pre-activation for 5-10 minutes; and adding 8-12 parts by weight of sodium hydroxide after microwave activation, performing saponification for 1.5-2.5 h at the temperature of 85-100 DEG C, and obtaining the target collecting agent. (2) taking a rutile rough concentrate raw material, adding the collecting agent, an inhibitor, an activating agent and a foaming agent,and carrying out primary flotation to obtain monazite rough concentrate and tailings; and (3) adding the collecting agent, the inhibitor, the activating agent and the foaming agent into the monaziterough concentrate, performing secondary flotation, and obtaining monazite concentrate and tailings, wherein the tailings are rutile concentrate. According to the beneficiation process, the rutile rough concentrate is effectively separated, the obtained monazite concentrate product and rutile concentrate product are high in quality, and the beneficiation process is environmentally friendly.

Description

technical field [0001] The invention relates to the field of mineral processing, in particular to a mineral processing technology and application of using a composite collector to separate monazite and rutile. Background technique [0002] Seaside placer is a very important deposit in the mineral resources of Hainan and Guangxi in my country. In addition to rich ilmenite reserves, this kind of deposit is accompanied by zircon, rutile, monazite and garnet with huge reserves. Wait. There are many such resources abroad, such as Australia, Malaysia, the United States, South Africa, Brazil, India, Mozambique, etc. [0003] Since there is little difference in specific gravity during the sorting process of rutile and monazite, fine particles of rutile and monazite are often mixed together in the process of shaker treatment, which not only reduces the quality of rutile, but also loses part of monazite, Therefore also reduced part loss, reduced the economic benefit of production ent...
