Gravity separation plays an important role in chrome ore processing and is the main method to concentrate chromium in the world. Chromite is weakly magnetic, can use strong magnetic separation to improve grade and increase the proportion of chromium. The fine-grained chromite tailings of low grade can be recovered by flotation method.
