Embodiment 1
[0019] Take 0.5 kg of natural jatropha seed oil fatty acid sulfated soap, 0.5 kg of industrial soap flakes with a fatty acid content greater than 78%, and 0.02 kg of Tween-20, add 50 kg of water and mix well to obtain a combined collector. For reverse flotation of calcium (magnesium) phosphorite, the flotation process conditions are as follows:
[0020] (1) Ore pre-treatment: 70% of the ore with a selected grade of 25-26% is crushed and wet ball milled to -200 mesh, and the pulp concentration is 75%;
[0021] (2) Primary roughing for magnesium removal: add 200g raw ore to 0.5L flotation cell, add 0.5L tap water to adjust slurry for 2min; first add inhibitor sulfuric acid 16.00kg / t, stir for 3min; then add combined collector 0.40kg / t t, stirring for 3 minutes; after inflating and bubbling, carbonate gangue minerals were removed by reverse flotation at room temperature, and the scraping time was 4 minutes.
[0022] With the reverse flotation magnesium removal collector configur...
Embodiment 2
[0024] Take 0.4 kg of natural jatropha seed oil fatty acid sulfated soap, 0.6 kg of industrial soap grains with a fatty acid content greater than 78%, and 0.04 kg of Tween-40, add 50 kg of water and mix well to obtain a combined collector. The calcium (magnesium) phosphorite is subjected to reverse flotation, and the flotation process conditions are carried out according to (1) and (2) in Example 1.
[0025] With the reverse flotation magnesium removal collector configured in Example 2 and the flotation process, raw ore P 2 o 5 Carbonate phosphate rock with a grade of 25.19% is enriched into concentrate P 2 o 5 The grade is 34.79%, the MgO content is 1.02%, and the concentrate P 2 o 5 The recovery rate is an excellent indicator of 91.23%.
Embodiment 3
[0027] Take 0.3 kg of natural Jatropha curcas seed oil fatty acid sulfated soap, 0.7 kg of daily-use soap with fatty acid content not less than 50%, 0.06 kg of Tween-60, add 50 kg of water and mix well to obtain a combined collector. Reverse flotation of calcium (magnesium) phospholithite was carried out with the same agent, and the flotation process conditions were carried out according to (1) and (2) in Example 1.
[0028] With the reverse flotation demagnesium collector configured in Example 3 and the flotation process, raw ore P 2 o 5 Carbonate phosphate rock with a grade of 25.13% is enriched into concentrate P 2 o 5 The grade is 34.87%, the MgO content is 1.04%, the concentrate P 2 o 5 The recovery rate is an excellent indicator of 91.87%.
