Column flotation for fine tin recovery
ABSTRACT. Wheal Jane Tin Mine, South West Cornwall, England processes a fine grained cassiterite ore (0.85% Sn) by a combination of gravity concentration and flotation. The material, too fine to be effectively recovered by gravity concentration (70% – 45 um) is deslimed at 4 um and treated by froth flotation to produce a low-grade tin ...Web
