Tin ores that contain high sulphide mineral contents have to undergo an additional process, whereby the ore is baked at 500600°C to burn the sulphur. Flotation is not as efficient for tin as it is for sulphide ores, it is becoming more frequently used to improve the amount of tin recovered from both primary ores and reprocessing to recover tin from processed waste material.
