Influence of Collectors on Flotation of Fine Tin Middlings after Gravity Separation

Abstract:

The study was aimed to recover tin minerals from fine tin middlings from Laos after gravity separation. The middlings had a tin grade of 0.5%, belonging to a refractory ore, so flotation was used to recover tin of them. Based on the research of influence of collector on flotation of fine tin middlings, an optimum index was obtained in the closed-circuit flotation. Finally, the concentrate with a tin grade of 3.45% and a tin recovery of 59.85% was obtained, which was concentrated by 6.9 times compared with the crude ore, which greatly improved the economic benefit for the concentrator and highly increases the efficiency of separation.
