  • Ferrochromium Alloys Manufacturing

    This method will conserve chromium and should reduce the capital and energy requirements for chromite reduction. Reduced products containing less than 2 wt-pct C and as low as 0.01 wt-pct C were obtained by reacting pellets of chromite and carbonaceous reductant mixtures at pressures of 0.1 to 1 torr and temperatures of 1,230° to 1,320° C.

  • Chromite Market - Global Industry Analysis and Forecast ...

    Chromite deposit can be divided into two main types: stratiform or layered deposits and podiform or alpine type chromite deposit. Stratiform deposits are formed by fractional crystallization of chromite. During this process, chromite spinel is one of the first minerals to crystallize. It sinks and settles within the magma chamber.

  • Chromite - Wikipedia

    Chromite ore can be mined to produce chromite concentrate.It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron. This ferroalloy, as well as chromite concentrate can introduce various health effects.
