Problems solved by technology

The use of traditional collectors - oleic acid, sodium oleate, tall oil, regulator - soda ash, inhibitors - water glass, sodium hexametaphosphate, tannin, dextrin, etc., can not meet the requirements Fluorspar concentrate
Therefore, the fluorspar resources in such tailings are often discarded directly and cannot be recycled.
[0004] In addition, because the traditional fluorite flotation agent needs to heat the slurry to 30 degrees Celsius, which increases energy consumption, thus pushing up the cost of fluorite production

Embodiment 1

[0034] The raw materials of this embodiment consist of 60 kg of saponified rubber seed oil, 3 kg of tributyl phosphate, 2 kg of Tween 80, 1 kg of sodium cetyl sulfonate, and 34 kg of water.

[0035] Preparation method: Add the above-mentioned substances in the stirring tank in sequence, under normal pressure, control the temperature of the stirring tank at 70-80°C, stir for 40-60 minutes and cool down to prepare low-temperature-resistant fatty acid saponification Receiver.

Embodiment 2

[0037] The raw materials of this embodiment consist of 67 kg of saponified rubber seed oil, 4 kg of tributyl phosphate, 2 kg of Tween 80, 2 kg of sodium cetyl sulfonate, and 25 kg of water.

[0038] Preparation method: Add the above-mentioned substances in the stirring tank in sequence, under normal pressure, control the temperature of the stirring tank at 70-80°C, stir for 40-60 minutes and cool down to prepare low-temperature-resistant fatty acid saponification Receiver.

[0039] The anti-low temperature type fatty acid saponification collector of the present invention can be used after being formulated into an aqueous solution with a concentration of 2-5%.

[0040] In a tungsten ore flotation plant in a high-altitude area in Yunnan, the annual slurry temperature is 5-25 degrees Celsius, and CaF in tungsten ore flotation tailings 2 Grade 19.63%, Ca 2 CO 3 The content reaches 50.16%. Due to the use of traditional collectors such as oleic acid and sodium oleate, the requir...

Abstract

The invention discloses a production method for collecting fluorite-contained tailings from rubber seed oil. The method comprises the following steps: (1) the rubber seed oil is prepared to a low-temperature resistant fatty acid saponified matter collecting agent; (2) the desliming classification treatment is performed for fluorite ore-contained flotation tailings; (3) the pulp mass concentration of the deslimed fluorite-contained tailings is controlled within 25-30%; and (4) the fluorite contained ore pulp is mineralized; and a four-six-segment direct flotation separation process is performed to obtain fluorite concentrate products with 90-95% of the fluorite (CaF2) content. The method has the following characteristics: the novel low-temperature resistant fatty acid saponified matter collecting agent prepared by the rubber seed oil has better collecting property on the fluorite in the fluorite-contained tailings; and the fluorite concentrates with 90-95% of the CaF2 grade can obtained through a simple elixir system and a shorter flotation technological process. Meanwhile, the collecting agent also has better collecting property on the fluorite ores under the condition of low temperature.

Description

technical field [0001] The invention relates to a production method for collecting fluorite-containing tailings by rubber seed oil, and belongs to the field of ore dressing agents and resource comprehensive utilization. Background technique [0002] Although there are many minerals containing fluorine on the earth, except for fluorite, there are dozens of them, but pure industrial fluorine can be obtained, and the only fluorine-containing mineral raw material for producing hydrofluoric acid is fluorite. Therefore, fluorite It is a very precious mineral resource. my country's fluorite mineral resources with (symbiotic) deposits (points) have large reserves and low utilization levels. Most mines cannot be recycled due to the limitation of comprehensive recycling technology for fluorite. [0003] Due to the lack of unified management, the main development and utilization of our country is CaF 2 Deposits with more than 50% content, a large amount of CaF 2 The ore whose grade ...
