Problems solved by technology

The most important thing in the separation of copper and molybdenum is to remove chalcopyrite and recover molybdenite. The most common collectors are xanthate collectors. Although xanthate collectors have good collection effects, they require a large amount of Therefore, choosing a suitable copper-molybdenum separation collector is the key to efficiently separate copper-molybdenum

Abstract

The invention relates to the technical field of copper-molybdenum separation, in particular to a collecting agent for copper-molybdenum separation, a flotation agent and a flotation method.The collecting agent comprises, by weight, 10-30 parts of a component shown in the formula 1-1 and 10-30 parts of a component shown in the formula 2-1, wherein the structural formulas of the formula 1-1 and the formula 2-1 are shown in the specification, Me and Me1 are H < + > or metal ions, and R1, R2 and R3 are alkyl groups or aromatic groups. The structure of the collecting agent has the characteristic of isoelectric isomer of nitrogen and sulfur, so that the synergistic effect between the two components is realized, and the copper-molybdenum separation effect is effectively improved.

Description

Technical field [0001] The present invention relates to the field of copper molybdenum separation technology, and more particularly to a catching agent, a flotation agent, and a flotation method for copper molybdenum separation. Background technique [0002] BACKGROUND OF THE INVENTION The following is only referred to as the information related to the present invention, and is intended to increase the understanding of the present invention by means of some basic technical knowledge associated with the present invention, which is not necessarily constituted Knowledge known to those of ordinary skill in the art. [0003] Molybdenum is a precious rare high melting metal. It is an important strategic material. The copper molybdenum ore is one of the main sources of molybdenum. The amount of molybdenum recovered in copper molybdenum ore accounts for 48% of the total molybdenum production of world molybdenum, due to vulcanized copper mine The same is easy to float, and the flora in th...
