Outline
To address the problems of high content of carbonate gangue, high oxidation rate, and severe mudding of lead-zinc oxide ore in Xinjiang, a detailed experimental study on mineral processing technology was carried out. The primary metallic elements in the ore that are of value for mineral processing and recovery are lead and zinc, with concentrations of 6.90% and 6.06%, respectively. Lead is present in lead oxide at a rate of 81.30%, and zinc is present in zinc oxide at a rate of 95.04%. By employing a process flow consisting of lead-oxygen-sulfur mixed flotation, flotation desliming and zinc oxide flotation, and using a compound phosphate that effectively suppresses carbonate gangue minerals, the process successfully prevented the flotation of carbonate gangue minerals, ensured the selectivity of the flotation process, and improved the grade of the lead-zinc concentrate. Through full closed-circuit process test, indicators of 50.32% lead grade, 3.76% zinc grade, and 80.84% lead recovery rate were achieved for the lead concentrate, while the zinc concentrate from the lead-zinc oxide ore exhibited a zinc grade of 35.73% with a lead grade of 4.21% and a zinc recovery rate of 75.62%, achieving efficient flotation recovery of this lead-zinc oxide ore.
