Embodiment 1

[0010] Example 1 Take 80g Turkish red oil, 80g triethanolamine oleic acid soap, 8g sulfonated oil, 12g fatty alcohol polyoxyethylene ether AEO-3, 8g sodium palmitate methyl fat sulfonate, 12g 30% C14 α-olefin sulfonate sodium Add it into a 500ml flask and stir for 15 minutes to fully mix the materials in the flask evenly to obtain a collector for phosphate rock reverse flotation to remove calcite.

[0011] Utilize the phosphate rock reverse flotation that present embodiment 1 makes to remove calcite collector to P 2 o 5 Content is 21.90%, MgO content is 0.51%, and CaO content is 51.80% Phosphorite is added 1.0kg per ton of raw ore to carry out reverse flotation to remove calcite, and obtain P 2 o 5 Concentrate of 30.48%, MgO content of 0.41%, CaO content of 51.15% concentrate, the recovery rate is 91.32%.

Embodiment 2

[0012] Example 2 Take 85g Turkish red oil, 85g triethanolamine oleic acid soap, 6g sulfonated oil, 9g fatty alcohol polyoxyethylene ether AEO-3, 6g sodium palmitate methyl fat sulfonate, 9g 30% C16 α-olefin sulfonate sodium Add it into a 500ml flask and stir for 15 minutes to fully mix the materials in the flask evenly to obtain a collector for phosphate rock reverse flotation to remove calcite.

[0013] Utilize the phosphate rock reverse flotation that present embodiment 2 makes to remove calcite collector to P 2 o 5 Content is 21.90%, MgO content is 0.51%, and CaO content is 51.80%. Add 1.0kg per ton of raw ore for reverse flotation to remove calcite, and get P 2 o 5 Concentrate of 31.48%, MgO content of 0.31%, CaO content of 51.46%, recovery rate of 92.32%.

Embodiment 3

[0014] Example 3 Take 90g Turkish red oil, 90g triethanolamine oleic acid soap, 4g sulfonated oil, 6g fatty alcohol polyoxyethylene ether AEO-3, 4g sodium palmitate methyl fat sulfonate, 6g 30% C16 α-olefin sulfonate sodium Add it into a 500ml flask and stir for 15 minutes to fully mix the materials in the flask evenly to obtain a collector for phosphate rock reverse flotation to remove calcite.

[0015] Utilize the phosphate rock reverse flotation that present embodiment 3 makes to remove calcite collector to P 2 o 5 Content is 21.90%, MgO content is 0.51%, and CaO content is 51.80% Phosphorite is added 1.0kg per ton of raw ore to carry out reverse flotation to remove calcite, and obtain P 2 o 5 Concentrate of 31.25%, MgO content of 0.38%, and CaO content of 51.18% concentrate, the recovery rate is 91.87%.

Abstract

The invention relates to a phosphate ore reverse flotation collecting agent for efficiently removing calcite. The phosphate ore reverse flotation collecting agent is composed of, by mass, 80%-90% of modified fatty acid and 10%-20% of composite surfactants in a compound mode. The modified fatty acid is composed of 50% of Turkey red oil and 50% of triethanolamine oleic soap in a compound mode. The composite surfactants are composed of 20% of sulfonated oil, 30% of fatty alcohol polyoxyethylene ether AEO-3, 20% of palmitic acid methyl ester sodium sulfonate and 30% of alpha-olefin sodium sulfonate in a compound mode. The phosphate ore reverse flotation collecting agent is suitable for a reverse flotation process for removing calcite from phosphate rock and has the characteristics of being excellent in selectivity and high in concentrate recovery rate.

Description

technical field [0001] The invention relates to a phosphate rock reverse flotation collector, in particular to a collector for efficiently removing calcite from phosphate rock. It belongs to the field of surfactants. Background technique [0002] Phosphate rock is an important strategic resource, mainly used in the preparation of phosphate and phosphate fertilizer. The production of phosphate and phosphate fertilizer requires the raw material of phosphate rock to be P 2 o 5 The content is above 30%, and the MgO content is below 2%. In nature, there are limited phosphate rocks that can reach such an index, and most low-grade phosphate rocks need to be processed to meet the requirements of high-quality phosphate rocks. Foam flotation is currently the most widely used beneficiation method in the phosphorus chemical industry, among which reverse flotation is the most common process for removing dolomite. This process is only applicable to phosphorites with high dolomite con...
