Primary raw materials like chrome ore and manganese ores are used for manufacturing different grades of Ferro alloys, refractories, chemicals etc. Depending on their characteristics are in great demand. The ores produced/ traded by the Group are much suited for bulk Ferro alloys producers like Ferro Chrome, Ferro Manganese and Silico Manganese.
Apart from chrome and manganese ore, the Group also trades in other primary raw materials and commodities viz.
