Formula and preparation method of marble saw mud flotation oxides

Abstract

The invention discloses a formula and a preparation method of marble saw mud flotation oxides. The preparation method comprises the following steps: S1, preparing a mixed material; S2, conducting heating and saponifying: firstly, weighing a certain amount of the mixed material A, putting the mixed material A into a reaction kettle, and then sequentially and separately adding water and solid sodium hydroxide; and S3, compounding a mixed fatty acid and a surfactant: in a reaction kettle, adding terpilenol, a TX emulsifier and sodium carbonate into the mixed material B in proportion, and conducting stirring for one hour at the temperature of 95 DEG C. A reagent in the formula is good in water solubility, good in dispersing effect and high in collecting capacity, so that the collecting performance of the agent is improved, agent consumption is reduced, and the flotation cost is saved; and the reagent in the formula is good in selectivity, the whiteness of flotation products is improved, and the advantage of performance complementation of high-carbon-chain fatty acid and low-carbon-chain fatty acid is fully exerted by utilizing the performance characteristics of the high-carbon-chain fatty acid and the low-carbon-chain fatty acid. The reagent in the formula is suitable for high-concentration fine fraction flotation, the flotation efficiency is improved, and huge economic benefits are brought to enterprises.

Description

technical field [0001] The invention belongs to the technical field of flotation agents, and in particular relates to a formula and a preparation method of marble saw mud flotation oxides. Background technique [0002] Due to the fine-grained (about 300 mesh) ore slime / saw slime has the characteristics of small mass and large specific surface area, a series of special behaviors will appear in the fine particles during the flotation process: First, agglomeration between different mineral particles is easy to occur And the formation of non-selective aggregation, so that selective separation is particularly difficult; the second is that the particles have a large specific surface area and surface energy, different minerals have high drug adsorption capacity, and the adsorption selectivity is poor; the third is that the quality of the particles is small , is easily entrained by water flow machinery and foam machinery; fourth, the effective contact efficiency of particles and bub...

[0002] Due to the fine-grained (about 300 mesh) ore slime / saw slime has the characteristics of small mass and large specific surface area, a series of special behaviors will appear in the fine particles during the flotation process: First, agglomeration between different mineral particles is easy to occur And the formation of non-selective aggregation, so that selective separation is particularly difficult; the second is that the particles have a large specific surface area and surface energy, different minerals have high drug adsorption capacity, and the adsorption selectivity is poor; the third is that the quality of the particles is small , easily entrained by water flow machinery and foam machinery; Fourth, the effective contact efficiency between particles and bubbles decreases, and the capture rate decreases

[0003] The above-mentioned behaviors are the main reasons for the slow flotation speed, low efficiency, poor selectivity and unstable flotation index of fine particle saw mud
