| titleOfInvention | A kind of flotation separation method for separating copper oxide ore and talc |
| abstract | The invention discloses a method for separating copper oxide concentrate and talc by flotation. Copper oxide minerals are used as raw materials, and sodium sulfide is added to the raw ore for grinding. After grinding, the pH value of the pulp is between 10-10.5, and cyclic pyrophosphate Sodium and water glass increase the negative potential of the mineral surface, improve the electrostatic repulsion between particles, and make the pulp fully dispersed; add the combined inhibitor of magnesium sulfate and valerate polyacrylamide; finally add diethylaminobutyl xanthate as copper ore It can be used as a collector of substances to achieve high-efficiency separation of copper oxide minerals and talc. The flotation reagent combination of the invention is low-toxic or non-toxic, has the characteristics of less dosage and good effect, and provides an environment-friendly and efficient method for flotation separation of copper oxide minerals and talc. |
