摘要
都龙锌锡多金属矿中的锡石嵌布粒度细,多年来仅采用常规单一的重选工艺回收锡石导致回收率偏低。随着细粒锡石浮选工艺的研究并应用于生产后,实现了细粒级锡石的高效经济回收,同时改善重选分选条件,提高了粗粒级锡石的回收率,锡综合回收率由45%左右提高到55%以上,经济效益显著,具有良好的推广应用前景。
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.
