Embodiment 1

[0022] Raw ore WO of a tungsten mine in Henan 3 The grade is 0.10%, and more than 94% of the tungsten exists in the form of scheelite, and the content of carbonate minerals such as calcite in gangue minerals is relatively high. The oxidized ore collector of the present invention is used to carry out a flotation closed-circuit test on the ore.

[0023] After adding conditioner and said collector 100~300g / t in raw ore, carry out rough separation to obtain rough separation foam product and product in rough separation tank; add inhibitor water glass to rough separation foam product, carry out three times of separation , to obtain the final scheelite concentrate product; add 50-150 g / t of the collector to the product in the roughing tank, and perform roughing to obtain the tailings product. Selected middlings and sweeping middlings are returned in sequence.

Embodiment 2

[0028] Raw ore WO of a tungsten mine in Hunan 3 The grade is 0.32%. Tungsten mainly occurs in scheelite, and the content of carbonate minerals such as calcite in gangue minerals is very high. The oxidized ore collector of the present invention is used to carry out a flotation closed-circuit test on the ore.

[0029] After adding conditioner and said collector 100~300g / t in raw ore, carry out rough separation to obtain rough separation foam product and product in rough separation tank; add inhibitor water glass to rough separation foam product, carry out three times of separation , to obtain the final scheelite concentrate product; add 50-150 g / t of the collector to the product in the roughing tank, and perform sweeping to obtain the tailings product. Selected middlings and sweeping middlings are returned in sequence.

Embodiment 3

[0034] Raw ore WO of a tungsten mine in Henan 3 The grade is 0.26%, and more than 80% of the tungsten exists in the form of scheelite, and the content of carbonate minerals such as calcite in gangue minerals is relatively high. The oxidized ore collector of the present invention is used to carry out a flotation closed-circuit test on the ore, and the flotation temperature is 10°C.

[0035] After adding conditioner and 100~300g / t of the collector to the raw ore, roughing is carried out to obtain the roughing foam product and the product in the roughing tank; the inhibitor water glass is added to the roughing foam product for three times of beneficiation , to obtain the final scheelite concentrate product; add 50-150 g / t of the collector to the product in the roughing tank, and perform sweeping to obtain the tailings product. Selected middlings and sweeping middlings are returned in sequence.

Abstract

The invention discloses a preparation method of an oxidized ore collecting agent and an application thereof. The oxidized ore collecting agent is prepared by mixing the following raw materials: 50-70% by mass of oleic acid, 20-30% by mass of sodium hydroxide, 20-30% by mass of water, 3-5% by mass of carboxymethylcellulose and 5-10% by mass of glycerol monostearate. The preparation method comprises the specific steps of: firstly, mixing oleic acid with sodium hydroxide; adding water to uniformly stir and heating the mixture to 50-60 DEG C; then adding carboxymethylcellulose to continuously stir till the mixture is emulsified to milk white paste; and further blending glycerol monostearate and uniformly stirring the mixture. The oxidized ore collecting agent disclosed by the invention can be applied to floating oxidized ores such as scheelite, lead-zinc oxide ores, rare earth ores and fluorite mine. Compared with other fatty acid collecting agents, the collecting agent shows relatively high selectivity on scheelite flotation. The WO3 grade and recovery rate of the floated tungsten concentrate are improved to a certain extent. The oxidized ore collecting agent disclosed by the invention has the characteristics of being simple to prepare, good in stability, good in dispersibility, high in selectivity and the like, and is suitable for being taken as a floating collecting agent for oxidized ores, in particular scheelite.

Description

technical field [0001] The invention relates to the field of flotation of oxidized ores, in particular to a preparation method and application of flotation collectors for oxidized ores, especially scheelite. Background technique [0002] At present, the most widely used collectors for scheelite flotation are fatty acid collectors, such as oleic acid and oxidized paraffin wax soap. Some combined collectors based on oleic acid have poor dispersibility and are difficult to dissolve in water at low temperature, which has a great adverse effect on the separation of oxidized ore. When scheelite and carbonate minerals are separated by flotation, a single oleic acid is used as a collector, which has poor selectivity and requires a large amount of water glass to suppress carbonate minerals such as calcite, resulting in high cost and poor separation effect. Therefore, finding and developing a collector with high selectivity and good dispersion for scheelite is one of the problems to ...
