Problems solved by technology

(2) The content of heavy metal ions and COD in the tail water exceeds the standard
[0011] Though above-mentioned these patents all relate to the flotation depressant of iron sulfide or zinc sulfide, and what have also relate to the method that adopts non-lime to carry out flotation, but by reading these patents, it can be known that these patents are not related to the present invention. The problem to be solved has nothing to do with it, and the disclosed technical scheme is more complicated than the flotation treatment scheme proposed by the present invention, and the materials used are also more, which is difficult to prepare and produce, so it still needs to be further improved

Abstract

The invention discloses a trithio-nonmetal acid salt and oligomer flotation inhibitor. The inhibitor consists of trithio-nonmetal acid salt and oligomer thereof, and inhibits flotation of zinc sulfideores by iron sulfide ores under natural pH condition. The trithio-nonmetal acid salt and the oligomer thereof comprise two molecular structural formula forms; and the two molecular structural formulas both have structural characteristics of the trithio-nonmetal acid salt and the oligomer thereof, wherein the trithio-nonmetal acid salt is nonmetal oxygen-contained acid salt. The inhibitor is adopted to inhibit flotation of zinc sulfide minerals by iron sulfide minerals by a light inhibition method of not adding lime through a flotation process; and compared with the pulp pH value of above 12 in the known flotation operation of the zinc sulfide minerals by adopting the lime as an inhibitor of the iron sulfide minerals, the pulp pH value in the flotation operation of the zinc sulfide minerals is obviously different, and is in a neutral range of 6-9.

Description

Technical field: [0001] The invention relates to an inhibitor of a flotation clean production method and its preparation and use method, in particular to an inhibitor for inhibiting iron sulfide ore flotation zinc sulfide ore under natural pH conditions and its preparation and use method. The invention relates to an inhibitor for inhibiting iron sulfide ore flotation zinc sulfide ore under natural pH conditions and a preparation method thereof, belonging to the field of mineral processing flotation reagents. Background technique: [0002] There are two commonly used flotation separation methods for zinc sulfide minerals and iron sulfide minerals at home and abroad. One is the priority flotation process in accordance with the operation sequence of flotation zinc sulfide minerals and then flotation iron sulfide minerals. In the operation of flotation zinc sulfide minerals, it is necessary to add lime to adjust the pH value of the slurry to be above 12 to suppress iron sulfide ...
