Abstract

A lead-zinc oxide flotation agent, which is composed of the following raw materials in parts by weight: 11-18 parts of No. 25 black medicine, 7.8-14 parts of butylamine black medicine, 20-25 parts of butyl xanthate, ethiazepine 35.7-50 parts, 4.5-8 parts of kerosene, 150-200 parts of sodium silicate, 30-50 parts of ammonium bicarbonate, 10-12 parts of pinitol oil. The lead-zinc oxide flotation agent provided by the invention has good flotation effect, is easy to prepare, has the advantages of low cost and high recovery rate, and is worthy of in-depth research and popularization and application in the flotation of such refractory lead-zinc minerals. In the flotation of lead-zinc oxide refractory ore, it is only necessary to mix eight kinds of substances in a certain proportion to synthesize a new flotation agent, which can greatly improve the recovery rate of lead-zinc concentrate and simplify the flotation workers and chemical workers. difficulty of operation.

Description

technical field [0001] The invention relates to the technical field of flotation of lead oxide minerals, in particular to a flotation agent for lead oxide minerals. Background technique [0002] Raw ore metal minerals mainly include sphalerite, pyrite, white lead ore, galena, followed by pyrite, smithsonite, chalcopyrite, hematite, lead alum, arsenite, etc., gangue Minerals are mainly: calcite, quartz, feldspar, calcium iron pyroxene, fluorite, barite and so on. Considering that the grade of lead-zinc raw ore is very high, the output of concentrate is large, and the oxidation rate is as high as 70%, the use of lead-zinc mixed flotation and then separation will result in a high mutual content rate between lead and zinc metals. The impurities of each concentrate exceed the standard, which affects the quality of the concentrate, so the optimal flotation is selected. [0003] At present, the beneficiation test research is carried out on high-grade lead-zinc mixed ore (Pb7.36%,...
