Embodiment 1

[0023] The scheelite flotation collector of this embodiment is prepared from the following raw materials by weight percentage: 28% of benzohydroxamic acid, 71% of modified fatty acid, and 1% of water glass, which are weighed according to the above weight percentages The raw material is to heat the modified fatty acid to 60°C-70°C, add benzhydroxamic acid and stir, then add water glass and stir for 1 hour, and stir evenly to prepare scheelite flotation collector.

[0024] Using the prepared scheelite flotation collector, the flotation grade of the raw ore is 0.39%, and the obtained titanium concentrate grade reaches 1.28%, and the recovery rate is a good indicator of 88.51%.

Embodiment 2

[0026] The scheelite flotation collector of this embodiment is prepared from the following raw materials by weight percentage: 30% of benzohydroxamic acid, 69% of modified fatty acid, and 1% of water glass, which are weighed according to the above weight percentages The raw material is to heat the modified fatty acid to 60°C-70°C, add benzhydroxamic acid and stir, then add water glass and stir for 1 hour, and stir evenly to prepare scheelite flotation collector.

[0027] Using the prepared scheelite flotation collector, the flotation grade of the raw ore is 0.39%, and the obtained titanium concentrate grade reaches 1.29%, and the recovery rate is a good indicator of 88.38%.

Embodiment 3

[0029] The scheelite flotation collector of this embodiment is prepared from the following raw materials by weight percentage: 32% of benzohydroxamic acid, 67% of modified fatty acid, and 1% of water glass, which are weighed according to the above weight percentages The raw material is to heat the modified fatty acid to 60°C-70°C, add benzhydroxamic acid and stir, then add water glass and stir for 1 hour, and stir evenly to prepare scheelite flotation collector.

[0030] Using the prepared scheelite flotation collector, the flotation grade of the raw ore is 0.39%, and the obtained titanium concentrate grade reaches 1.32%, and the recovery rate is a good indicator of 88.89%.

Abstract

The invention provides a scheelite flotation collecting agent and a preparation method thereof. The scheelite flotation collecting agent is prepared from, by weight, 25%-50% of benzohydroxamic acid, 50%-75% of modified fatty acid and 0.5%-2% of water glass. The scheelite flotation collecting agent is used for scheelite flotation, is good in low temperature resistance, good in selectivity and highin collecting capacity, and can obtain scheelite rough concentrate with the high grade and the high recovery rate. The preparation method of the scheelite flotation collecting agent is wide in sourceof the raw materials and simple in preparation process, the produced scheelite flotation collecting agent is good in dissolving performance, strong in collecting force, high in selectivity and good inlow temperature resistance, the fine scheelite grade can be effectively improved after all the components cooperate, the beneficiation technical index is effectively improved, economic benefits are remarkable, and good market popularization prospects are achieved.

Description

technical field [0001] The invention relates to a flotation collector, in particular to a scheelite flotation collector and a preparation method thereof, and belongs to the technical field of mineral flotation collectors. Background technique [0002] There are more than 20 kinds of tungsten minerals and tungsten-containing substances found in nature, but only wolframite and scheelite are worth mining. Although the reserves of tungsten ore resources in my country are large, their particle size is fine and there are many associated metals, but scheelite reserves are Poor, fine, and miscellaneous deposits account for the majority. Flotation technology is the most important beneficiation method for scheelite. In recent years, such resources have been increasingly exhausted. The efficient development and utilization of tungsten ore has become an important problem that must be solved to achieve efficient resource utilization. . [0003] CN106733217A discloses a kind of preparation...
