Application of selective flocculation using starch to separate chromite from serpentine has been investigated. It was determined that starch has a specific affinity towards chromite which can be exploited in selective flocculation. However, it was found that this could only be achieved when the amount of serpentine in the chromite-serpentine mixture is below 30% by weight and in the presence of a dispersant such as sodium silicate or ultrasonic treatment of the pulp.
