Abstract

The invention discloses an ore selection method for treating tin, lead and zinc polymetallic oxidized ore. The ore selection method includes: firstly, crushing and ball-milling raw ore; then directly subjecting the raw ore subjected to ball-milling to lead and zinc oxide ore mixed floatation and feeding floating ore into foam products; feeding products in a floatation tank to a primary table concentrator for gravity concentration to obtain tin concentrate, first-section middlings and tailings; feeding the first-section middliings to a secondary table concentrator for gravity concentration to obtain tin concentrate, second-section middlings and tailings; subjecting the second-section middlings to grinding and then combining the same into the ore subjected to lead and zinc oxide mixed floatation. The foam products which are silica tailings are subjected to reverse floatation to get rid of silica, so that the products in the flotation tank are final lead and zinc mixed concentration. By the adoption of lead and zinc mixed floatation and reverse flotation of the lead and zinc mixed concentrate to get rid of the silicon, recovery rate of useful metals is increased in the mixed floatation, types and dosage of medicament are reduced, environmental pollution is low, and purposes of conforming to the state policy of cleaner production and circular economy and achieving energy conservation, emission reduction, consumption reduction and comprehensive utilization of resources are achieved.

Description

technical field [0001] The invention belongs to the technical field of beneficiation, and in particular relates to a beneficiation method of tin-lead-zinc polymetallic oxide ore. Background technique [0002] my country's lead-zinc oxide resources are abundant, of which low-grade refractory lead-zinc oxide resources account for a considerable proportion. For this part of resources, due to the lack of efficient processing technology, they have not yet been developed and utilized on a large scale, resulting in A lot of waste of resources. The low-grade tin-lead-zinc polymetallic oxide ores on the surface of the Dachang mining area in Nandan County, Hechi, Guangxi are rich in reserves, and the ores contain valuable metals such as tin, lead, antimony, silver, zinc, indium, etc. It exists in lead ore, and indium exists in zinc ore. The content of various metals in this ore is low, and the oxidation rate of lead and zinc is above 90%. Due to the complexity and difficulty of separ...
