Abstract

The invention relates to the technical field of non-ferrous metal beneficiation, in particular to a non-copper sulphide ore inhibitor and application thereof. The non-copper sulphide ore inhibitor isprepared from the following components in parts by mass: 1-3 parts of xanthan gum, 1-2 parts of pectin and 1-2 parts of arabic gum. The non-copper sulphide ore inhibitor is simple in preparation, lowin cost and green and environment-friendly and has a quite high inhibition effect on molybdenite, galena, sphalerite, pyrite and other sulphide ores in the copper bulk concentrate. With application ofthe inhibitor, efficient flotation separation of chalcopyrite and other sulfide minerals can be achieved.

Description

technical field

[0001] The invention relates to the technical field of non-ferrous metal beneficiation, in particular to a non-copper sulfide ore inhibitor and its application. Background technique

[0002] Copper is an important rare metal and strategic reserve resource, the average content of which is only 1 / 100,000 in the earth's crust. Chalcopyrite is the most important source of copper extraction, and chalcopyrite is usually associated with sulfide minerals. According to statistics, nearly 75% of copper and 50% of molybdenum in the world are produced from copper-molybdenum ore. Copper-molybdenum ore is generally mixed flotation, and then copper-molybdenum separation is often carried out by means of copper-inhibited floating molybdenum or molybdenum-suppressed floating copper. At present, the most used method is to inhibit chalcopyrite flotation molybdenite. Commonly used copper sulfide inhibitors mainly include sulfide (sodium sulfide, sodium hydrosulfide, etc.), cyan...
