Embodiment 1

[0008] Example 1. Take 36 kg of saponified cottonseed oil and 6 kg of sodium sulfosuccinic acid dioctanoate, and mix to obtain the basic substance. Add 525kg of water and mix to obtain a collector, which can be used to produce P-containing 2 o 5 High-grade phosphorous concentrate greater than or equal to 37%.

Embodiment 2

[0009] Example 2. Take 40kg of saponified cottonseed oil and 8kg of sulfosuccinic acid dioctanoic acid sodium salt, and mix them to obtain the basic substance. Add 960kg of water and mix to obtain a collector, which can be used to produce P-containing 2 o 5 High-grade phosphorous concentrate greater than or equal to 37%.

Embodiment 3

[0010] Example 3. Take 40kg of saponified cottonseed oil and 8kg of sulfosuccinic acid dioctanoic acid sodium salt, and mix them to obtain the basic substance. Add 300kg of water and mix to obtain a collector, which can also be used to produce P-containing 2 o 5 High-grade phosphorus concentrate greater than or equal to 37%, but the fluidity of the collector is slightly poor.

Abstract

Cellophane reverse flotation collector is mixed with base material and water. Wherein, the former comprises with share, saponification material of cotton oil 38~45, dioctyl sodium sulfosuccinate 10~20; the proportion of base material and water is 1:5~20. The collector can make the product grade not less than 37% when the grade of raw material down to 24%, which means important for the usage of low grade phosphorus ore source. It is also characterized in that the recovery rate of concentrate is high, with low content of MgO and low cost. This invention can also be fit to production of all kinds' phosphorus ores.

Description

technical field [0001] The invention relates to the beneficiation technology of phosphate rock. Background technique [0002] The higher the grade requirement of phosphorous concentrate, the better. The collectors currently used in the beneficiation process are better at being able to produce P in raw ore. 2 o 5 When the content is greater than 28%, the grade of phosphorous concentrate produced can reach P 2 o 5 Greater than or equal to 34%, but the MgO content in the concentrate, the recovery rate of the concentrate, and the cost of beneficiation are still unsatisfactory. Contents of the invention [0003] The object of the present invention is to provide a new collophanite reverse flotation collector. It can be obtained from P 2 o 5 The content is 24~30% in the raw ore, P 2 o 5 Phosphorus concentrate with a content greater than or equal to 37%, high concentrate recovery rate, low MgO content, and low beneficiation cost. [0004] Technical scheme of the present i...
