Embodiment 1

[0013] This agent is to dissolve sodium sulfite, sodium humate and potassium permanganate in water at a mass ratio of 50:25:25, and add it as usual after standing for 48 hours.

[0014] When in use, add this agent at 800g / ton of ore at the slurry mixing tank (1) (taking 6% antimony in gold concentrate as an example, it can be increased or decreased according to the amount of antimony), and in sweeping one (2), fine ore Add this agent at 100g / ton of ore, 240g / ton of ore, and 300g / ton of ore at election one (4) and selection two (5). The reaction time is 1-3 minutes after adding this agent in each section. Other operations are the same as conventional flotation.

Embodiment 2

[0016] The difference from Example 1 is that potassium sodium sulfite and potassium humate are used to replace sodium sulfite and sodium humate respectively.

Embodiment 3

[0018] The difference from Example 1 is that sodium sulfite, sodium humate and potassium permanganate are dissolved in water at a mass ratio of 40:30:30.

[0019] The flotation agent of the present invention has an inhibitory effect on pyrite and arsenopyrite as gold carriers in the gold concentrate after the gold ore associated with gold and antimony is enriched by flotation, and the inhibitory effect on stibnite Weaker, it can significantly increase the difference in floatability between stibnite, pyrite and arsenopyrite. Compared with traditional flotation, the agent of the present invention can increase the separation effect of gold and antimony by more than 30%.

Abstract

The invention discloses a floatation reagent used for separating gold from antimony. The floatation reagent comprises sulfite, humic acid salt and potassium permanganate, wherein the mass ratio of the sulfite to the humic acid salt to the potassium permanganate is 40-50:25-30:25-30. The floatation reagent restrains iron pyrite and arsenical pyrite, but weakly restrains antimony glance, and can obviously increase the floatability difference between the antimony glance and the iron pyrite and the arsenical pyrite, and compared with traditional floatation, the reagent can improve the effect of separating the gold from the antimony by above 30%.

Description

technical field [0001] The invention belongs to the field of gold beneficiation, and in particular relates to a flotation reagent for separating gold and antimony. Background technique [0002] Gold ore contains many impurities such as arsenic, sulfur, antimony, carbon, etc. Currently, the second-stage roasting method commonly used can only remove the effects of arsenic, sulfur, and carbon on gold leaching, but cannot effectively eliminate the harm caused by antimony in gold ore , and this method has the defects of high cost and low efficiency, and the existing mineral processing method has no practical and effective reagents to realize the separation and flotation of gold and antimony. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the existing ore dressing agents cannot effectively separate gold and antimony, and provide a flotation agent for gold and antimony separation. [0004] The technical scheme adopted by th...
