Problems solved by technology

When raw ore ore P 2 o 5 When the content is less than 22%, it is difficult to produce qualified phosphorus concentrate products. Even if qualified quality concentrate products are produced, the technological process is complicated, resulting in a low concentrate recovery rate

Embodiment 1

[0015] Example 1: Using a mixture of 0.5 parts by weight of acidified oil of fur bran oil and 0.5 parts by weight of acidified soybean oil as a raw material, the mixture was heated to 80°C, added with lye, stirred and saponified, and the pH was controlled to be 7-8, and the saponified Add 0.04 parts by weight of BK-204 to the semi-finished product to obtain a finished product.

Embodiment 2

[0016] Example 2: Using a mixture of 0.7 parts by weight of acidified furfur oil and 0.3 parts by weight of acidified soybean oil as raw materials, heat the mixture to 90°C, add lye and stir for saponification, control pH = 7-8, and then use the saponified Add 0.06 parts by weight of BK-205 to the semi-finished product to obtain a finished product.

Embodiment 3

[0017] Example 3: Using a mixture of 0.8 parts by weight of acidified oil of fur bran oil and 0.2 parts by weight of acidified soybean oil as raw materials, the mixture was heated to 100°C, added with lye and stirred for saponification, and the pH was controlled to 7-8, and then the saponified Add 0.1 parts by weight of BK-201 to the semi-finished product to obtain a finished product.

Abstract

The invention relates to a reverse flotation collector of carbonate phosphate ores and a preparation method thereof. The collector is essentially composed of the following raw materials by weight proportion: 0.5-0.8 part of acidified raw bran oil, 0.5-0.2 part of acidified soy oil, 0.01-0.1 part of foamer which takes semi-finished products after saponification as benchmark. The preparation methodof the collector is that: the mixture of the acidified raw bran oil and the acidified soy oil is taken as raw material, which is heated to 80-100 DEG C, added with soda lye and stirred for saponification, the pH value is controlled between 7 to 8, and then the foamer is added into the mixture to obtain finished products. The collector has the advantages of strong collecting capability, high selectivity, small dosage and low temperature resistance, etc., and is suitable for the ore dressing production of carbonate phosphate ores and various phosphorus ores; even when the grade of carbonate phosphate ores is reduced to 17%, the quality of the produced phosphate concentrate still can meet qualification requirements; in addition, the invention has simple preparation technique, easy operation,high recover rate of ore concentrate, low content of MgO in ore concentrate and low ore dressing cost.

Description

technical field [0001] The invention relates to an ore flotation collector, in particular to a carbonate phosphate rock reverse flotation collector and a preparation method thereof. Background technique [0002] my country's phosphorus resources rank second in the world. But the national average grade of phosphate rock is only 16.95%, P 2 o 5 There are only 110.8 billion tons of rich ore with a grade greater than 30%, and more than 85% of the low- and medium-grade phosphate rocks are collophanites that are not easy to be selected and enriched. Due to the backward development technology of phosphate rock and too few large-scale state-owned backbone mines, phosphate rock is far from meeting the needs of the development of phosphorus chemical industry; in addition, random digging by townships and private enterprises has caused serious waste of resources. At present, the reverse flotation collector of carbonate phosphate rock used in the beneficiation process is better in raw...
