Abstract

The invention discloses a lead-zinc oxide ore flotation agent. The lead-zinc oxide ore flotation agent comprises, by weight, 11-18 parts of dithiophosphate 25, 7.8-14 parts of ammonium dibutyl dithiophosphate, 20-25 parts of sodiumn-butylxanthate, 35.7-50 parts of diethyldithiocarbamate, 4.5-8 parts of kerosene, 150-200 parts of sodium silicate, 30-50 parts of ammonium bicarbonate and 10-20 parts of terpenic oil. The lead-zinc oxide ore flotation agent has the advantages of being good in flotation effect, easy to prepare, low in cost and high in recovery rate, thereby being worthy of intensive study and popularization and application in flotation of lead-zinc ore difficult to separate. During flotation of the lead-zinc oxide ore difficult to separate, it is only required that the eight materials are proportionally mixed to form the new flotation agent, the recovery rate of lead-zinc concentrate can be substantially improved, and operating difficulty is reduced for flotation workers and agentia workers as well.

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%...
