The process of chromite ore mining can be divided into 2 areas: 1. Feed preparation. 2. Concentration. The feed preparation stage involves the introduction of various physical separation equipment including crushers, screens and grinding mills. The principal function of this stage is size reduction in preparation for the concentration phase.
Aug 25, 2016· Chromite ores are the only source of chromium. The majority of chromite ores are processed into an intermediate product called high carbon ferro-chrome, or charge chrome, an alloy containing greater than 50% Cr, about 6-8% C, varying amounts of Fi (0-4%, depending on the process used), with the balance Fe.

Based on type, the global chromite market can be segmented into high chromium chromite, high iron chromite, and high aluminum chromite. Based on application, the global chromite market can be segregated into stainless steel, chemicals, pigments, refractories, and foundry sand.
Refractory manufacturing involves four processes: raw material processing, forming, firing, and final processing. Figure 11.5-1 illustrates the refractory manufacturing process. Raw material processing consists of crushing and grinding raw materials, followed if necessary by size classification and raw materials calcining and drying.
Chromite is a mineral that contains chromium. It is considered a strategic mineral, which generally means that it is necessary for military and industrial use during periods of national emergency.
