Abstract
The studies indicate that microwave radiation pretreatment is an effective method to modify ilmenite surface properties and improve ilmenite flotability. After exposure to microwave radiation for a short time, ilmenite recovery was increased by about 20%. The specific surface area of ilmenite samples underwent a significant change with microwave exposure time; also new phases were observed. Microwave exposure speeded up the oxidation of ferrous ions to ferric ions on the ilmenite surface. This resulted in an enhancement of oleate ion adsorption and therefore improved ilmenite flotation behaviour.
