Embodiment 1

[0011] Example 1: Mix 50 parts of cottonoleic acid and 50 parts of foaming agent, heat to about 80°C, stir to mix evenly, and obtain a finished water-soluble weathered apatite ore foam flotation collector.

[0012] The water-soluble weathered apatite ore froth flotation collector prepared in Example 1 was used in the flotation test of differentiated apatite ore in Vietnam: when the slurry temperature was 25°C, the raw ore P 2 o 5 When it is 14.65%, a closed-circuit process of one coarse, two fine and one sweep is adopted, and the amount of collector added in each ton of flotation phosphate rock is 0.4kg, and the concentrate P can be obtained through direct flotation. 2 o 5 It was 31.96%, and the recovery rate reached a good index of 85.65%.

Embodiment 2

[0013] Example 2: Mix 45 parts of cotton oleic acid with 5 parts of rapeseed acid and 50 parts of foaming agent, heat to about 80 ° C, stir to mix evenly, and obtain water-soluble weathered apatite ore foam flotation Finished product.

[0014] The water-soluble weathered apatite ore froth flotation collector prepared in Example 2 was used in the flotation test of differentiated apatite ore in Vietnam: when the slurry temperature was 25°C, the raw ore P 2 o 5 When it is 14.65%, a closed-circuit process of one coarse, two fine and one sweep is adopted, and the amount of collector added in each ton of flotation phosphate rock is 0.4kg, and the concentrate P can be obtained through direct flotation. 2 o 5 It was 30.65%, and the recovery rate reached a good index of 81.48%.

Embodiment 3

[0015] Example 3: Mix 40 parts of cotton oleic acid with 10 parts of rapeseed acid and 50 parts of foaming agent, heat to about 80 ° C, stir to mix evenly, and obtain water-soluble weathered apatite ore foam flotation Finished product.

[0016] The water-soluble weathered apatite ore froth flotation collector prepared in Example 3 was used in the flotation test of differentiated apatite ore in Vietnam: when the slurry temperature was 25°C, the raw ore P 2 o 5 When it is 14.65%, a closed-circuit process of one coarse, two fine and one sweep is adopted, and the amount of collector added in each ton of flotation phosphate rock is 0.4kg, and the concentrate P can be obtained through direct flotation. 2 o 5 It was 29.37%, and the recovery rate reached a good index of 78.96%.

Abstract

The invention relates to a water-soluble weathering phosphorite mineral foam flotation collecting agent which comprises the following substances in part by weight: 40-50 parts of cotton oleic acid, 0-10 part of vegetable oleic acid and 50 parts of foaming agent. The preparation method comprises the following steps of: mixing the 40-50 parts of cotton oleic acid, 0-10 part of vegetable oleic acid and 50 parts of foaming agent, heating to 80 DEG C, and stirring until the substances are mixed uniformly. The collecting agent provided by the invention can be applied to foam floatation of phosphorite minerals similar to severe Vietnam weathering argillization, and has the characteristics of high selectivity, less using amount, simple production manufacturing technology, low mineral selection cost and high recycling ratio compared with the traditional positive flotation collecting agent of weathering phosphorite minerals.

Description

technical field [0001] The invention relates to an ore foam flotation collector, in particular to a water-soluble weathered apatite ore foam flotation collector. Background technique [0002] There are a series of small and medium-sized sedimentary metamorphic apatite deposits in Yunnan, parts of Hubei, Vietnam, Laojie, Liangshan, Thanh Hoa and other places. shape and irregular shape. Because these areas are in the subtropical monsoon climate for a long time, the leaching and weathering of the surface deposits are serious. The useful minerals of apatite are mainly fluoroapatite, gangue minerals include dolomite, calcite, mica, quartz, etc., and accessory minerals include pyrite, galena, sphalerite, magnetite, hematite , pyrolusite, rutile and garnet, etc. For a long time, due to the severe muddy weathering of this kind of ore, the collector in the flotation has poor selectivity to its ore particles, and the concentrate grade after flotation is low, and the foam is sticky ...
