ore sorting is an established technology in physical separation that has proved extremely effective in mining operations for a variety of minerals including chrome TOMRA s XRT sorting delivers high recovery rates on Chrome mine no need for additional com minution It is a dry process that requires no water or reagents and is
The chrome ore extracted from these mines is processed into various products including ferrochrome which is essential for stainless steel production The processing involves various stages including crushing screening and separation Not all mining sites have their own wash plants; instead many rely on independent operators known as
Sensor based ore particle sorting offers a powerful method for pre concentration or waste rejection early in the comminution process The technology analyzes each and every rock particle on line for unique physical and chemical properties

The results show that the useful component in the ore is % Cr 2 O 3 and the chrome containing minerals are mainly hard chromium main reason that affects the magnetic separation effect is that the hard chrome spinel in the chrome ore is non magnetic and the magnetic separation effect is not ideal
