The rate of adsorption of oleate soap onto a Nigerian hematite in an aqueous medium was determined from 29 to 60 degrees C using the differential analysis method. The activation energy and frequency factor were determined at 57.1 kJ mol(-1) K(-1) and 4.0 x 10(3) liter mol(-1) min(-1), respectively,

Crude Nigerian baryte was floated with sodium oleate as collector at varying oleate concentrations, pulp pH, and temperatures. Using "pure" baryte selected from the crude baryte, oleate adsorption densities at the baryte-water interface were determined also at varying oleate concentrations, pulp pH,
