Embodiment 1

[0015] The collector is made according to the following method: 0.3 part of α sulfonated saturated fatty acid salt, 0.3 part of α sulfonated oleate or α sulfonated linoleate, 0.10 part of fatty acid soap, 0.05 part of dodecane Sodium sulfate, 0.05 sodium fatty alcohol polyoxyethylene ether sulfate, and 0.2 parts of kerosene are mixed. Based on 1 part of the mixture, add 0.5 part of the mixture into 40-50°C water, stir for 30 minutes and cool to normal temperature to obtain the collector of the present invention. When the raw ore grade P 2 o 5 When MgO is 23.89%, and MgO is 6.23%, use the collector of the present invention to add 600 grams per ton of phosphate rock to carry out reverse flotation, and adopt a rough and fine reverse flotation process to obtain phosphorus-containing 2 o 5 Phosphate concentrate with a grade of 33.09%, Mg0 of 0.71%, and a recovery rate of over 94%.

Embodiment 2

[0017] The collector is made according to the following method: 0.35 part of α sulfonated saturated fatty acid salt, 0.35 part of α sulfonated oleate or α sulfonated linoleate, 0.10 part of fatty acid soap, 0.05 part of dodecane Sodium phenyl sulfonate, 0.05 part of fatty alcohol polyoxyethylene ether sodium sulfate, and 0.1 part of kerosene are mixed. Based on 1 part of the mixture, add 0.5 part of the mixture into 40-50°C water, stir for 30 minutes and cool to normal temperature to obtain the collector of the present invention. When the raw ore grade P 2 o 5 When MgO is 23.52%, and MgO is 5.89%, use the collector of the present invention to add 600 grams per ton of phosphate rock to carry out reverse flotation, and adopt a rough and fine reverse flotation process to obtain phosphorus-containing 2 o 5 Phosphate concentrate with a grade of 33.15%, Mg0 of 0.70%, and a recovery rate of over 94%.

Embodiment 3

[0019] The collector is made according to the following method: 0.35 part of α sulfonated saturated fatty acid salt, 0.35 part of α sulfonated oleate or α sulfonated linoleate, 0.15 part of fatty acid soap, 0.025 part of tetradecane Sodium sulfate, 0.025 fatty alcohol polyoxyethylene ether sodium sulfate, and 0.1 part of kerosene are mixed. Based on 1 part of the mixture, add 0.5 part of the mixture into 40-50°C water, stir for 30 minutes and cool to normal temperature to obtain the collector of the present invention. When the raw ore grade P 2 o 5 When MgO is 24.10%, and MgO is 6.03%, use the collector of the present invention to add 600 grams per ton of phosphate rock to carry out reverse flotation, and adopt a rough and fine reverse flotation process to obtain P-containing 2 o 5 Phosphate concentrate with a grade of 32.48%, Mg0 of 0.87%, and a recovery rate of over 95%.

Abstract

The invention discloses a gapatite demagnesia reverse flotation collector agent. The gapatite demagnesia reverse flotation collector agent comprises preparation materials that alpha sulfonated saturated fatty acid salt, alpha sulfonated oleate or alpha sulfonated linoleate, fatty acid sope, malkyl sulfate or sodium alkyl benzene sulfonate, fatty alcohol polyoxyethylene ether dium sulfate, keroseneand water; the preparation method is to mix the materials together in a certain proportion; with a mixture as the standard one part, the mixture is added into a certain proportion water, then the mixture is stirred, and the collector agent is obtained. The gapatite demagnesia reverse flotation collector agent is low in preparation cost, and the collector agent can be carried out under 5-30 DEG Cof ore pulp temperature, and the collector agent is good in selectivity, strong in collection ability, and the flotation foam is good and non-sticky.

Description

technical field [0001] The invention relates to the field of mineral processing, in particular to a reverse flotation composite collector for magnesium removal from colphosphane and a preparation method thereof. Background technique [0002] Collophanite contains a large amount of dolomite and calcite, and the content of magnesium oxide is mostly between 2% and 7%. It is difficult to beneficiate. Therefore, how to use a collector with strong collection capacity to reverse flotation to remove magnesium has become the key. The research on low-grade collophanite beneficiation collector with high magnesium content is also of great significance for making full use of a large amount of low-grade collophanite. [0003] At present, there are some documents and patent applications in the published prior art, among which "A Collophosite Reverse Flotation Collector and Its Preparation Method" with application number 201610684733.0 also discloses a collector with better effect , but th...
