Difficulties in separation of fine cassiterite and current research status of flotation reagent application
Due to the increasingly depleted Tin resources,fine cassiterite has become a critical ore resource.This paper discusses its characteristics,such as difficult separation,low dissemination size and factors affecting the flotation process.It highlights that disseminated particle size and slime coating are two key issues impacting the flotation of fine cassiterite and elaborates on the influence of unavoidable ions on the flotation of fine cassiterite.During the cassiterite flotation process,various types of collectors and regulators impact the flotation effect of cassiterite.This paper introduces the role of pH value regulator,activator and inhibitor in cassiterite flotation and the mechanism of flocculant and cassiterite.Studying the application status of flotation reagents can provide a reference for improving the flotation index of fine tin ore and solving the problems of mineral slime coating and unavoidable ions.
