Abstract
The invention relates to a collecting agent for direct and reverse flotation of phosphorite, which solves the problems of inconvenient storage, transportation and use, more consumption, high mineral dressing cost, poor collecting capability, low mineral dressing recovery rate of low-grade phosphorite or low concentrate quality of the existing collecting agent. The composition is prepared by mixing the following components in parts by weight: 15-20 parts of oxidized paraffin and 1 part of additive, wherein the additive is prepared by mixing the following components in parts by weight: 1.8-2 parts of methanol, 1-1.2 parts of n-butanol and 10-12 parts of butyl phosphate, and adding the additive into the oxidized paraffin dissolved by heating, uniformly stirring and cooling to normal temperature.
Description
technical field:
The present invention is relevant with phosphorus ore valuable mineral foam flotation collector.
background technology:
Rock phosphate in powder, after broken, levigate, adds successively ore pulp adjusting agent, gangue mineral inhibitor, valuable mineral collecting agent in ore pulp.The hydrophobic bubble floating that adheres to stirring, inflation generation of valuable mineral phosphate scrapes to flotation device liquid level, becomes phosphorus concentrate after dehydration.Also can reverse flotation gangue mineral.
Existing both suitable in alkaline medium direct flotation to be also adapted at the collecting agent of reverse flotation in acid medium be by aliphatic acid, hydrocarbon-type oil, the oil-in-water emulsion that multiple polar compound and water are made, transportation and store inconvenience, needs to stir rear use after long-term placement.Consumption is many, and beneficiation cost is high, concentrate product quality not high (concentrate grade is 22% left and right only).During ore dressing, as by effect of sulfuric acid, be inhibitor consumption is many, the ore-dressing technique index that obtains not as good as the index obtaining as inhibitor with phosphoric acid.
summary of the invention:
The object of this invention is to provide a kind of consumption few, storage and convenient transportation, flotation is with low cost, applicable positive and negative floatation process, low temperature resistant, during ore dressing, only with sulfuric acid, as inhibitor, can obtain good index, collecting ability is strong, when phosphorus ore grade is low, still can produce the phosphate rock floating collecting agent of high-grade phosphorus heading.
The present invention is achieved in that
Phosphate rock floating collecting agent of the present invention, it is mixed and is formed by the component of following weight portion:
Oxidized paraffin wax 15-20
Additive 1
Described additive is mixed and is formed by the component of following weight portion:
Methyl alcohol 1.8-2
N-butanol 1-1.2 phosphoric acid fourth fat 10-12,
Additive is added in the oxidized paraffin wax of heating for dissolving, stir be cooled to normal temperature water-soluble solid.
Collecting agent provided by the invention and existing collecting agent comparison, its advantage mainly contains:
Collecting agent provided by the invention is not only applicable to the mineral processing production of carbonate phosphorus ore reverse flotation, can be used for the mineral processing production of other various low-grade phosphate ore stone direct flotations yet.The present invention is convenient to store and transportation, easy to use, can be used for low-grade phosphate ore ore dressing.Collecting agent provided by the invention is produced high-grade phosphorus heading for flotation of phosphate rock and is improved 10% left and right than the existing collecting agent rate of recovery, and concentrate grade improves 2 percentage points of left and right.And when phosphorus ore grade is low to moderate 20%, the phosphorus concentrate quality of producing still reaches the utilization of a large amount of low-grade phosphate ore resources of high-quality product ，Zhe Dui China of concentrate grade 32% left and right, has very important meaning.Collecting agent provided by the invention has strong, the selective height of collecting ability, consumption is few, low temperature resistant, beneficiation cost is low and apply the advantages such as wide.The present invention can reduce ore dressing phosphoric acid amount used (raw ore per ton reduces phosphoric acid consumption and is 5-10 kilograms), and only with sulfuric acid, makes inhibitor during ore dressing and just can obtain while adopting other collecting agent ore dressing, the index with phosphoric acid as inhibitor acquisition.Because available sulfuric acid is as inhibitor, the reagent cost that adjusting agent, inhibitor and collecting agent form is low.
the specific embodiment:
Phosphate rock floating collecting agent provided by the invention adds oxidized paraffin wax mixing by additive and forms, and the mixed proportion of additive and oxidized paraffin wax soap is 1:18(weight ratio); The composition of additive (by weight) comprises that 1.9 parts of methyl alcohol, 1.1 parts of n-butanols and 11 parts of mixing of phosphoric acid fourth fat form.
Phosphate rock floating collecting agent provided by the invention, its preparation method is: by weight, first with 11 parts, 1.9 parts of methyl alcohol, 1.1 parts of n-butanols and phosphoric acid fourth fat, be mixedly configured into additive, then by solid oxide heating paraffin to 90 ℃ until be dissolved as liquid state, finally add additive, stir and be cooled to normal temperature.
The present invention applies in the phosphate rock floating of Leibo Region, Sichuan Province.The phosphorus ore of flotation is containing P
