Embodiment 1
[0046] This example takes a copper-gold ore as the object. The raw ore contains 2.29% copper and 0.5 g / t gold, and the main components are chalcopyrite, pyrite, quartz, calcite, pyroxene, feldspar and the like.
[0047] like figure 1 As shown in the figure, the flotation of copper and gold ore is carried out using a high-efficiency frother for copper and gold ore flotation, including the following steps:
[0048] S1. Grinding classification:
[0049] The copper-gold ore is crushed to less than 8mm in three stages, then grinded, and then classified by a cyclone to obtain a cyclone classification overflow product with a fineness of 45% below 0.074mm, and water is added to increase its concentration. Adjusted to 30% to 35% to obtain pulp;
[0050] S2, slurry mixing: to the slurry obtained in step S1, add 300 g / t of sodium carbonate and 400 g / t of water glass, and after the reaction is sufficient, the first slurry is obtained; then, 50 g / t of copper sulfate is added to the first...
Embodiment 2
[0066] This example takes a copper-gold ore as the object. The raw ore contains 0.89% copper and 0.73 g / t gold, and the main components are chalcopyrite, pyrite, calcite, pyroxene, feldspar, and bentonite.
[0067] S1. Grinding classification:
[0068] The copper-gold ore is crushed in three stages to less than 12mm, then grinded, and then classified by a cyclone to obtain a cyclone classification overflow product with a fineness of 72% below 0.074mm, and water is added to increase its concentration. Adjusted to 30% to 35% to obtain pulp;
[0069] S2, slurry mixing: to the slurry obtained in step S1, add sodium carbonate 400g / t, water glass 400g / t, after the reaction is sufficient, obtain the first slurry; then, add copper sulfate 90g / t to the first slurry t, after the reaction is sufficient, the second slurry is obtained; finally, 180 g / t of isopentyl xanthate, 10 g / t of butylammonium black medicine, and 20 g / t of foaming agent are added to the second slurry, and the third s...
Embodiment 3
[0075] This example takes a copper-gold ore as the object. The raw ore contains 0.67% copper and 0.53 g / t gold, and the main components are chalcopyrite, pyrite, quartz, feldspar and the like.
[0076] S1. Grinding classification:
[0077] The copper-gold ore is crushed to less than 10mm in three stages, then grinded, and then classified by a cyclone to obtain a cyclone classification overflow product with a fineness of 68% below 0.074mm, and water is added to increase its concentration. Adjusted to 30% to 35% to obtain pulp;
[0078] S2, slurry mixing: to the slurry obtained in step S1, add sodium carbonate 200g / t, water glass 200g / t, after the reaction is sufficient, obtain the first slurry; then, add copper sulfate 70g / t to the first slurry t, after the reaction is sufficient, the second slurry is obtained; finally, 140 g / t of isopentyl xanthate, 20 g / t of butylammonium black medicine, and 36 g / t of foaming agent are added to the second slurry, and the third slurry is obta...
