Chromite is not only the raw materials of metallurgy and chemical industry, but also acts as one of the important national strategic resources. However, according to the range of the world, both the reserves and production of chromite are small in China. The proven minerals are small, and nearly half of them are lean ores currently. On the other hand, with the rapid development of stainless steel and ferroalloy industry, there is a great demand for chromite finished products. In the condition of supply-demand imbalance, the chromite import rises rapidly, and related industries are faced with serious cost pressure, which poses a threat on the security of the national economy. Thus, it’s meaningful to improve the comprehensive utilization of Chromite.

    SLon as a state-controlled company takes the responsibility of processing technology transformation, and is always active in the research of maximum utilization of mineral resources. Its original invention SLon WHIMS solves these problems successfully which have puzzled researchers for a long time, creating an precedent in the industry. As yet, there have been about 200 SLon WHIMS applied in the chromite beneficiation in the world, and greatly improve the recovery rate of chromite.
