Problems solved by technology

[0006] (2) The content of heavy metal ions and COD in the tail water exceeds the standard
[0012] 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

Disclosed is an inhibitor through select flotation of disulfo-nonmetal acid salt and oligomer of the disulfo-nonmetal acid salt and a preparation and using method. The inhibitor is formed by the disulfo-nonmetal acid salt and the oligomer of the disulfo-nonmetal acid salt and inhibits zinc sulfide ore of select flotation by iron sulfide ore in a natural pH condition. The disulfo-nonmetal acid saltand the oligomer of the disulfo-nonmetal acid salt comprises two molecular structure forms. The two molecular structure forms have the structural characteristics of the disulfo-nonmetal acid salt andthe oligomer. The disulfo-nonmetal acid salt is non-metallic oxygen-containing acid salt. By means of the inhibitor, the zinc sulfide ore of select flotation by the select flotation process can be achieved through a slight inhabiting method that lime cannot be added in the select flotation process, the pH value of ore pulp of operation of the zinc sulfide ore of select flotation in a 6-9 neutralrange is different from the pH value of more than 12 of ore pulp of operation of the zinc sulfide ore of select flotation by using a known method that lime is used as an inhibitor of the iron sulfideore significantly.

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 ...
