| titleOfInvention | A kind of multi-metal sulfide ore-dressing technique containing time pig copper |
| abstract | The present invention relates to a kind of multi-metal sulfide ore-dressing technique containing time pig copper, belong to technical field of mineral processing.The method of the invention is: takes the iron powder that granularity is 10 ~ 150 μm, is made into the suspension of 1% ~ 10%；In grinding machine or agitator tank, add iron powder suspension by ore pulp the 0.1% ~ 1% of Ore solid masses, after carrying out conventional flotation method subsequently, obtain final concentrate product；Add and between the iron powder in grinding machine and mineral grain, constitute galvanic element, make copper ion free in ore pulp replaced, decrease free copper ion to sphalerite and pyritous activation so that between mineral, floatability difference becomes big, concentrate product is little containing phenomenon mutually, thus improves the index of dressing product.It is good that the method for the invention has floatation indicators, saves medicament, simplifies the advantages such as beneficiation flowsheet. |
