Flotation Study on One Kind of Low-grade Tailing of a Certain Polymetallic Mine in Henan Province
摘要
Abstract
An exploration experiment was carried out on the flotation of low-grade scheelite in a polymetallic tailing in Henan.The minelogical characteristics of the tailings process show that the scheelite content of the sample is 0.059％,which is slightly lower than the boundary grade.The scheelite is a valuable recovery component in the tailings.The comprehensive recovery test adopts the flotation process,rough selection and pre-enrichment-heating and drug removal-dilution and selection.Through a small closed-circuit test,the final result is 0.14％of the scheelite,the tungsten grade of 30.99％.The rate of 76.94％is the technical index of beneficiation.This study realises the efficient recovery of tungsten in tailings,which provides a reference for the recovery and utilization of polymetallic tailings of the same type.关键词
