Chromite an overview ScienceDirect Topics

Chromite ore can be separated in a high-strength field, despite the presence of iron impurities. The choice of method depends on several factors, primarily the type of the gangue. In some cases, separation and dressing methods are optimized to take into account other useful elements, such as PGM (platinum group metals) in South Africa, where noble metals extraction (besides chromium) is of

Primary processing of chromite ores and ore-preparation of

Chromite ore dressing technology is developed to take into account mineralogical, petrographic, and physicochemical features of raw material and its components. A possibility is shown for complex use of mineral resources of chromite deposits by improving the quality of ore-dressing wastes and intermediate products being a raw material for refractories, foundry sand, and antiburning-on paint.
