Abstract: Forcassiterite is disseminated as fine particles in ore from Dulong zinc and cassiterite polymetallic deposit. The recovery rate has been low by conventional gravity separation process over the years. With fine cassiterite flotation process being researched and applied to production, the gravity separation conditions have improved and the recovery rate of fine grained cassiterite has improved, coarse cassiterite has realized efficient recycling economy at the same time. The cassiterite comprehensive recovery rate increased from about 45% to higher than 55% with remarkable economic benefit and good prospect of popularization and application.
