Problems solved by technology

[0003] However, there are not many reports on the beneficiation process of garnet flotation in rutile coarse concentrate in seashore placer beneficiation. Currently, sodium oleate flotation method is usually used, and the useful method is mainly obtained by inhibiting garnet. Minerals cannot fully obtain garnet concentrates, and it is difficult to fully obtain garnet concentrates from rutile crude concentrates by flotation to achieve effective separation of rutile concentrates and garnet concentrates. Therefore, it is necessary to find a composite flotation The medicament is matched with the corresponding sorting garnet and rutile positive flotation beneficiation process to realize simultaneous improvement of the grade and recovery rate of rutile concentrate and garnet concentrate, fully improve the effective utilization rate of placer resources, and optimize and improve The beneficiation technology of such rutile resources has important practical application value

Abstract

The invention provides a mineral processing process for sorting garnet and rutile based on composite flotation reagents, comprising the steps of: (1) preparing a composite garnet collector: including 20-25 parts of tall oil and 30-35 parts of oxidized paraffin wax soap , 20-30 parts of palm oil and 12-18 parts of sodium fatty acid methyl ester sulfonate; saponification reaction after microwave pre-activation; It is water glass, the activator is copper sulfate, the flotation concentration is 45-55%, and the garnet rough concentrate and rutile concentrate are obtained; (3) selection flotation: the dosage of garnet composite collector is 85-95 / t , the inhibitor is water glass, the activator is copper sulfate, the flotation concentration is 35-40%, and the garnet concentrate and rutile medium ore are obtained. The invention realizes the positive flotation separation of garnet and rutile, simultaneously improves the grade and recovery rate of rutile concentrate and garnet concentrate, and has simpler process steps.

Description

technical field [0001] The invention relates to the technical fields of chemical industry and metallurgy, in particular to a beneficiation process for separating garnet and rutile based on composite flotation reagents. Background technique [0002] The coastal placer mine is a very important deposit in the mineral resources of Hainan and Guangxi in my country. In addition to the abundant rutile reserves, these deposits are associated with huge reserves of zircon and garnet. Due to the small difference in specific gravity during the sorting process of rutile and garnet, in the process of shaking table, fine-grained rutile and garnet are often mixed together, which not only reduces the quality of rutile, but also loses some garnets. It leads to the waste of placer resources and reduces the economic benefits of production enterprises. Therefore, realizing the effective sorting and recycling of rutile and garnet is one of the important conditions for increasing production and e...
