Embodiment 1

[0031] The raw material processed in this example is Mozambique rutile rough concentrate of Hainan Haituo Mining Co., Ltd., wherein the rough concentrate contains TiO 2 88.26%, including P 0.78%. Among them, rutile is the main component, and there are also some monazite, zircon and a small amount of garnet.

[0032] A kind of beneficiation process utilizing composite collector to separate monazite and rutile, comprising the following steps:

[0033] (1) Preparation of collector: by weight, 10 parts of tall oil, 25 parts of oxidized paraffin soap, 50 parts of palm oil, 15 parts of sodium fatty acid methyl ester sulfonate are mixed, microwave preactivation 8min, microwave power 10kg / kw, microwave frequency 2500MHz; after microwave activation, add 10 parts by weight of sodium hydroxide, and saponify at 100°C for 1.5h to obtain the target collector;

[0034] (2) Rough separation: take rutile coarse concentrate raw material, add collector 250g / t prepared in step (1), inhibitor w...

Embodiment 2

[0037] The raw material processed in this example is a rutile rough concentrate in Australia of Fujian Wensheng Mining Co., Ltd., wherein the rough concentrate contains TiO 2 89.31%, including P1.09%. Among them, rutile is the main component, and there are also some monazite, zircon and a small amount of garnet.

Abstract

The present invention provides a kind of ore dressing process and application of using composite collector to separate monazite and rutile, said ore beneficiation process includes the following steps: (1) by weight, 10 to 15 parts of tall oil, 25 parts of oxidized paraffin wax soap ~35 parts, palm oil 40~50 parts, sodium fatty acid methyl ester sulfonate 10~15 parts, microwave preactivation 5~10min; Saponification for 1.5 to 2.5 hours to obtain the target collector; (2) Take the rutile crude concentrate raw material, add the above-mentioned collector, inhibitor, activator, and foaming agent, and perform the first flotation to obtain monazite Coarse concentrate and tailings; (3) add monazite coarse concentrate to the above-mentioned collector, inhibitor, activator, foaming agent, and carry out the second flotation to obtain monazite concentrate and tailings, the tailings The mine is rutile concentrate. The beneficiation process of the invention effectively separates the rutile rough concentrate to obtain monazite concentrate products and rutile concentrate products with high quality and 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...
