Composite collecting agent and application thereof in chalcopyrite flotation

[0031]Example 1:

[0032]A composite collector of the present invention, 2-phosphonate-1,2,4-triecarboxylic acid and dibly hydrazine of mass ratio of 8: 2.

[0033]The composite inhibitor of the present embodiment is applied to a brass mine in Gansu (Cu product is 0.45%, and the pulse stone is mainly quartz, square solution, Huangli and magnetite).figure 1As shown, the specific process is as follows: First, the brass mine is mainly grounded to 70.074 mm, and the mass ratio of -0.074 mm ore is 70%, the slurry concentration is 45%, and then the sodium carbonate is adjusted to 8, and the composite inhibitor is added. (Mixture of water glass, propanoic acid and sodium carboxymethylcellulose sodium mass) and a composite collector (1-phosphonate-1,2,4-tricarboxylic acid) , Then add but yellow medicine, 2-phosphonate-1,2,4-tricarboxylic acid and butterpartum mass ratio of 8: 2, and the agent of the composite capture agent needs to be separated separately. After room temperature, a crude four-free sweep was 300g / t of 300 g / t, and the amount of composite receptant was 80g / t, and the amount of foam 2 # oil was 30 g / t; the fine composite inhibitor The amount of 100 g / t, fine two is 50 g / t, fine three and fine four are blank selection; the amount of the composite collector is 30g / t, the foam 2 # oil 15g / t), the order of China is returned After the closed-circuit flotation process, the Cu product obtained in copper concentration was 26.36%, the recovery rate was 91.31%, SIO2The content is 4.85%, and the recovery is 0.28%.

[0055]Example 2:

[0056]A composite trapping of the present invention comprises a mass ratio of 6: 4 having a trimethylphosphonoate and acetine nitrogen.

[0057]The composite inhibitor of the present embodiment is applied to a high-grade brass mine in Tibet (Cu product is 0.65%, and the pulse mineral is mainly the flotation process of quartz, Changshi and Hui Stone, and the yellow iron ore content. The process is as follows: Under -0.074 mm, the mass ratio of -0.074 mm ore is 65%, the slurry concentration is 40%, then the sodium carbonate is adjusted to 9, and the composite inhibitor (mass of 6) is added. : 3: 1 water glass, oxalic acid and carboxymethylcellulose sodium) and composite collectors (first addition of trimethylphosphonomethyl acetate, then ethyl nitrogen, trimethylphosphonoate and B The mass ratio of the sulfur nitrogen is 6: 4, and the agent of the composite capture agent needs to be added separately during the subsequent process), and a crude three-precision is 350 g / t for 350 g / t at room temperature. Composite recapture The amount of dosage is 100g / t, the amount of the foam 2 # oil is 40g / t; the amount of the fine compound inhibitor is 150 g / t, the fine two is 50 g / t, the fine three is a blank selection; sweep a composite capture agent The amount of 50g / t, the foam 2 # oil 20g / t; the amount of the composite capture agent is 25 g / t, the foam 2 # oil 10g / t), the closed flotation flow returned by the middle mineral sequence, The copper concentration of Cu is 30.25%, the recovery rate of 94.09%, the copper coarse concentrate, SIO2The content was 9.75%, and the recovery rate was 0.35%.

[0058]Example 3:

[0059]A composite trapping of the present invention comprising 2-hydroxyphosphononic acid and butlammonium butmony ammonium drugs having a mass ratio of 7: 3.

[0060]The composite inhibitor of the present embodiment is applied to a high-sulfur low-copper-copper-copper mine (Cu product is 0.34%, and the pulse mineral is mainly the flotation process of Huangding, Changshi and Dolomite, and a small quantity of quartz). The specific process is as follows: Under -0.074 mm, the mass ratio of ore is 60%, and the slurry concentration is 35%, then the sodium carbonate is adjusted to 10, and the composite inhibitor (mass ratio is 6: 1). 3 of the mixture of water glass, malonic acid and carboxymethylcellulose sodium sodium) and composite trapping (2-hydroxyphosphonic acid first, additional butmite black drug, and 2-hydroxyphosphonic acid and The mass ratio of butmantantal black medicine is 7: 3, and the drugs of the composite capture agent are added separately from the subsequent process), and a crude four-free sweep is taken at room temperature (the coarse-selected composite inhibitor is 450g / t, composite The amount of ceiling agent is 60g / t, and the amount of foaming agent 2 # oil is 25g / t; the amount of complex inhibitor is 200g / t, the fine two is 100g / t, the fine three and fine four are blank selection; A composite receptant is 30g / t, a foam 2 # oil 15g / t), after the order of the medium ore is returned to the closed flotation process, the Cu product obtained in the copper concentrate is 24.72%, the recovery rate of 88.58% copper coarse Seiki, SIO2The content was 7.51%, and the recovery rate was 0.23%.
