Abstract
The present invention relates to a collecting agent of the reverse flotation of carbonate type phosphorite ores, which is formed by mixing dry basis substances and water, wherein the dry basis substances comprise the following constituents: 90 to 99% of high fatty acid sponifying object of which the fatty acid content is not less than 50% and 1 to 10% of diethyl phthalate; a compounding ratio of the dry basis substances to the water is 1:20 to 70. Compared with the prior art, when the grade of raw material ores is below 22%, products produced by the collecting agent of the reverse flotation of carbonate type phosphorite ores can also reach the index of qualified ore concentrate. The present invention also has the characteristics of high ore concentrate recovery rate, low MgO content in the ore concentrate and low ore dressing cost. The present invention is not only suitable for the ore dressing production of the carbonate type phosphorite ores, but also can be applied to the ore dressing production of all kinds of phosphorus ores.
Description
The present invention relates to the technique of preparing of rock phosphate in powder.
Grade requirement to the rock phosphate in powder raw material in the chemical fertilizer production is high more good more ,-as high-grade rock phosphate in powder be meant the phosphorus concentrate of P2O5 content more than 32%.In the actual exploitation of rock phosphate in powder, the rock phosphate in powder that can reach the high-grade requirement is always limited, needs low-grade phosphate ore stone is carried out ore dressing under a lot of situations, in the hope of reaching the requirement that obtains the high-grade rock phosphate in powder.The collecting agent that in ore-dressing technique, uses at present, reasonable is can be at raw ore P2O5 content greater than 28% o'clock, the product quality of producing can reach the qualified concentrate containing index, when raw ore P2O5 content less than 28% the time, the product of producing is difficult to reach the qualified concentrate containing index.When P2O5 content was carried out ore dressing greater than 28% raw ore, though product can reach the qualified concentrate containing index, MgO content, beneficiation cost in the concentrate rate of recovery, the concentrate were still not satisfactory in addition.
The objective of the invention is to: a kind of new reverse flotation capture agent for carbonate type phosphate rock ore is provided, and the P2O5 content of the raw ore that it can be suitable for is 22%, and concentrate rate of recovery height, and the MgO content in the concentrate is low, and beneficiation cost is low.
The present invention is achieved in that collecting agent is mixed by butt material and water; Wherein the component of butt material comprises, content of fatty acid is not less than 50% the saponified 90-99% of higher fatty acids, phthalic acid diethyl ester 1-10%; The proportioning of butt material and water is 1: 20～70.
In the above-mentioned reverse flotation capture agent for carbonate type phosphate rock ore, the saponified preferably industrial soap flakes of described higher fatty acids or industrial neat soap or daily soap.
Compared with the prior art, the present invention has adopted new material component.Collecting agent of the present invention can be low by 22% o'clock in the grade of raw ore, and the product of being produced still can reach the qualified concentrate containing index.This has important effect for the utilization of a large amount of low-grade phosphate ore stone resource of China.The present invention also has the characteristics that MgO content is low, beneficiation cost is low in concentrate rate of recovery height, the concentrate.The present invention not only is applicable to the ore dressing production of carbonate-type phosphorite ore, and can be applied in the ore dressing production of various rocks phosphate in powder.
Below in conjunction with the specific embodiment the present invention is described in further detail.
Embodiment 1: get content of fatty acid greater than 78% industrial soap flakes 930kg, { C6H4 (COOC2H5) 2}70kg obtains the butt material to phthalic acid diethyl ester (being commonly called as phenethyl ester oil) after the mixing.Obtain collecting agent after adding water 50000kg stirring, utilize this collecting agent can produce phosphorus concentrate.
Embodiment 2: get content of fatty acid greater than 78% industrial neat soap 900kg, phthalic acid diethyl ester 100kg obtains the butt material after the mixing.Obtain collecting agent after adding water 70000kg stirring, utilize this collecting agent can produce phosphorus concentrate.
Embodiment 3: get content of fatty acid and be not less than 50% daily soap 990kg, phthalic acid diethyl ester 10kg obtains the butt material after the mixing.Obtain collecting agent after adding water 20000kg stirring, utilize this collecting agent can produce qualified concentrate containing.
Claims (2)
1, a kind of reverse flotation capture agent for carbonate type phosphate rock ore is characterized in that: collecting agent is mixed by butt material and water; Wherein the component of butt material comprises, content of fatty acid is not less than 50% the saponified 90-99% of higher fatty acids, phthalic acid diethyl ester 1-10%; The proportioning of butt material and water is 1: 20～70.
2, reverse flotation capture agent for carbonate type phosphate rock ore according to claim 1 is characterized in that: described higher fatty acids is saponified to be industrial soap flakes or industrial neat soap or daily soap.
