Abstract

The invention relates to the technical field of non-ferrous metal sulfide ore beneficiation, and discloses a collecting and foaming agent for copper-nickel sulfide ore beneficiation, which comprises the following components: carbon disulfide 28.0-33.8%wt, diethylamine 36.4-41.9%wt, propylene Nitrile 24.0‑28.2%wt, butylamine black drug 4.9‑12.6%wt, fusel oil 1.7‑9.5%wt, ethanol 3.0‑5.0%wt, n-butanol 1.0‑2.0%wt, sodium hydroxide 1.0‑3.0%wt The present invention also proposes a method for preparing a foaming agent for beneficiation of copper-nickel sulfide ore, including the following steps: S1: adding raw materials; S2: stirring and cooling; S3: adding acrylonitrile dropwise. The invention can obviously improve the mineral processing technical index, and can obtain a higher concentrate grade than the original collector; compared with the traditional collector of copper-nickel sulfide ore, the synthesis process is relatively simple, the material loss is small, and the copper-nickel mineral processing recovery rate increased.

Description

technical field [0001] The invention relates to the technical field of beneficiation of non-ferrous metal sulfide ore, in particular to a collecting foaming agent for beneficiation of copper-nickel sulfide ore and a preparation method thereof. Background technique [0002] Copper-nickel sulfide ore is a copper-nickel symbiosis mining area that both copper ore and nickel ore have. Although the extraction of nickel from oxidized ores is an important way to improve the guarantee of resource utilization, due to the problems of difficult flotation, the need for smelting technology, high cost and imperfect process technology, the laterite nickel ores mainly composed of oxidized ores are currently The development and utilization of nickel resources is still dominated by sulfide copper-nickel ore, and 2 / 3 of the global nickel production still comes from sulfide ore, which is an important source of nickel. [0003] Most of the copper-nickel sulfide deposits belong to the magmatic fu...
