The mainly process of chrome ore processing is gravity separation.Sometimes low intensity magnetic separation or high-intensity magnetic separation will be used to deal with the chrome concentrate for a second processing to improve the grade of the chrome. Also some ores treated by flotation, but the gravity separation is still the main processing way for chrome ores.
