The invention provides a low-grade phyllite type lead zinc ore beneficiation method. Through the steps including raw ore levigation, levigation, lead roughing, lead scavenging, lead fine selection, zinc roughing, zinc scavenging, zinc fine selection and the like, lead concentrate and zinc concentrate are finally obtained. Phyllite type lead zinc ore obtained through beneficiation with the method is good in beneficiation index, high in separating effect and suitable for application and popularization, and the beneficiation method is stable, efficient, high in adaptive capacity, good in beneficiation effect, high in comprehensive recovery index and low in production cost.
Description
technical field [0001] The invention belongs to the field of mineral processing, in particular to a mineral processing method of low-grade phyllite-type lead-zinc ore. Background technique [0002] my country's lead-zinc resources are rich but complex in nature, mainly manifested in the fact that there are many lean ores, few rich ores, many small ores and few large ones, complex types of deposits, non-concentrated spatial distribution, and large ore-forming age, among which phyllite-type lead-zinc deposits are the most complex. The phyllite-type lead-zinc deposit is different from the traditional common lead-zinc deposit types. The lead-zinc grade contained in the deposit is low, the occurrence form of metal minerals is complex, the types of gangue minerals are diverse, and there are many carbon-bearing slate minerals. Strong capacity and severe mudification will seriously affect the recovery of lead, zinc and associated elements, making comprehensive recovery difficult. ...
