A typical gravity concentration circuit recovers about 50–60% cassiterite (Lepetic, 1987) but significant values in the fine size are lost in the gravity tailings.Application of flotation and development of selective collectors have made it possible to recover fine cassiterite from the gravity tailings, which has resulted in improvement of overall plant recovery values to over 80%.

Aluminum-containing minerals in iron ore are detrimental to blast furnace and sinter plant operations. The two major aluminum-containing minerals in iron ore are kaolinite (Al 2 (Si 2 O 5)(OH) 4) and gibbsite (Al(OH) 3). Some progress has been made in using flotation to separate kaolinite from hematite.
