Abstract
The rival effects of pore penetration and surface spreading on the collector efficiency of straight chain hydrocarbons (of chain lengths C6 to C16) during coal froth flotation were examined. For the hydrocarbons considered in this study the maximum flotation yield is obtained with a hydrocarbon chain length of C12, that is dodecane. The flotation yield of shorter chain length hydrocarbons has been shown to be retarted by the penetration of the liquids into the coal pores: effectively reducing their surface concentration. The yield with the longer chain length hydrocarbons ( > C12) is retarded by viscosity effects which effectively reduce the rate of surface spreading of the liquid over the coal surface. This viscosity effect can be overcome if a sufficiently long conditioning time is allowed prior to flotation.
