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 present invention relates to the technical field of copper-molybdenum separation, in particular to a collector, flotation agent and flotation method for copper-molybdenum separation, wherein the collector contains 10 to 30 parts by weight of formula 1-1 Components and 10 to 30 parts by weight of components shown in Formula 2-1, wherein the structural formulas of Formula 1-1 and Formula 2-1 are as follows: the Me, Me 1 for H + or metal ion, R 1 , R 2 , R 3 For alkyl or aromatic groups. The structure of the collector of the present invention has the characteristics of nitrogen-sulfur isoelectric, thereby realizing the synergy between the two components and effectively improving the separation effect of copper and molybdenum.

Description

technical field [0001] The invention relates to the technical field of copper-molybdenum separation, in particular to a collector, a flotation agent and a flotation method for copper-molybdenum separation. Background technique [0002] The following content in the background technology only refers to the information related to the present invention understood by the inventor, and aims to increase the understanding of the present invention by explaining some basic technical knowledge related to the present invention. Knowledge known to those of ordinary skill in the art. [0003] Molybdenum is a precious rare high-melting point metal and an important strategic material. Copper-molybdenum ore is one of the main sources of molybdenum. The amount of molybdenum recovered from copper-molybdenum ore accounts for 48% of the world's total molybdenum production. Due to copper sulfide ore Both chalcopyrite and molybdenite are easy to float, and the buoyancy of chalcopyrite and molybde...
