Problems solved by technology

However, flotation requires a large amount of fatty acid raw materials. Due to the relatively low price of fatty acids, the dispersibility and selectivity of fatty acids are poor, resulting in long flotation time and slow flotation speed, resulting in large equipment and space required for flotation.

Embodiment 1

[0018] Mix the fatty acid soap obtained from fatty acid saponification with diethyl phthalate, wherein diethyl phthalate accounts for 10% of the total mass of the mixture, and the fatty acid soap accounts for 90% of the total mass of the mixture, at a constant temperature of 40~50°C Emulsify for 1-1.5 hours to obtain a collector that efficiently removes carbonate in collophanite. When raw ore P 2 o 5 Content of 21%, MgO content of 5% collephosite, adding 600 g / t raw ore collector for reverse flotation operation, 0.7% MgO content in the concentrate was obtained in 4.5 minutes of flotation time, MgO removal rate reached 90% %, compared with the flotation of fatty acid soap without adding diethyl phthalate (flotation time is 7 minutes, △ε / △t=0.264), the flotation rate of carbonate minerals was shortened by 36%. △ε / △t=0.33, an increase of 20%.

Embodiment 2

[0020] Mix the fatty acid soap obtained from fatty acid saponification with diethyl phthalate, wherein diethyl phthalate accounts for 15% of the total mass of the mixture, and the fatty acid soap accounts for 85% of the total mass of the mixture, at a constant temperature of 40~50°C Emulsify for 1-1.5 hours to obtain a collector that efficiently removes carbonate in collophanite. When raw ore P 2 o 5 content of 21%, MgO content of 5%, adding 600 g / t of raw ore collector for reverse flotation operation, the MgO content in the concentrate is 0.7% in 3 minutes of flotation time, and the MgO removal rate reaches 91% %, the flotation time was shortened by 57% compared with the fatty acid soap flotation without adding diethyl phthalate (flotation time was 7 minutes, △ε / △t=0.382), and the carbonate mineral The flotation rate △ε / △t=0.51, increased by 25%.

Embodiment 3

[0022] Mix the fatty acid soap obtained from fatty acid saponification with diethyl phthalate, in which diethyl phthalate accounts for 20% of the total mass of the mixture, and the fatty acid soap accounts for 80% of the total mass of the mixture, at a constant temperature of 40~50°C Under emulsification for 1 to 1.5 hours, a collector for highly efficient removal of carbonate in colphosphane was obtained. When raw ore P 2 o 5 content of 21%, MgO content of 5%, adding 600 g / t of raw ore collector for reverse flotation operation, the MgO content in the concentrate is 0.7% in 2 minutes of flotation time, and the MgO removal rate reaches 92 %, the flotation time was shortened by 71% compared with the fatty acid soap flotation without adding diethyl phthalate (flotation time was 7 minutes, △ε / △t=0.57), and the carbonate mineral The flotation rate △ε / △t=0.77, increased by 26%.

Abstract

The invention relates to a collecting agent capable of efficiently removing carbonate minerals in collophane. The technology of the collecting agent includes the steps that (1) a saponification reaction is carried out on fatty acid with the content of oleic acid with an 18 carbon chain and linoleic acid with an 18 carbon chain larger than 65%, (2) diethyl 1,2-phenylenediacetic acid with the mass percent ranging from 5% to 25% is added into the saponification product at the temperature ranging from 40 DEG C to 50 DEG C to carry out emulsification, and obtaining the collecting agent capable of efficiently removing the carbonate minerals in the cellophane, and (3) the collecting agent is used for collecting the carbonate minerals in the cellophane in a reverse-flotation mode. Under the condition that the same number of collecting agents are added, and the MgO contents in obtained concentrates are similar, compared with 7-minute-flotation-time fatty acid saponification flotation without adding the diethyl 1,2-phenylenediacetic acid, the floatation time is shortened by more than 36%, and the carbonate-mineral flotation speed is quickened by more than 20%.

Description

Technical field [0001] The present invention involves a collective of carbonate minerals in high -efficiency dehydration of phosphorus ore. Background technique [0002] With the rapid development of the phosphate fertilizer industry, the mining and dosage of phosphate ore have also risen sharply, and the overall product of the phosphate ore has decreased. More than 90%of phosphorus ore needs to be flotal to obtain phosphate essence for phosphate production.Floating requires a large amount of fatty acid raw materials. Due to the relatively low price of fatty acids, the dispersion is not good, and the selectivity is poor, resulting in a long floating time, a slow floating speed, and a large device and space required for flotation.To this end, it is necessary to study the recovery agent that can efficiently remove carbonate minerals. Invention content [0003] The purpose of the present invention is to overcome the lack of existing technologies and provide a recovery agent that pr...
