Abstract

This invention relates to a method of forming sintered and/or pre-reduced chromite agglomerates (typically briquettes or pellets) using and/or containing a SiC Composite (a form of silicon carbide containing material) as a reductant for use in the production of ferrochrome alloy. The method includes the steps of: preparing a mixture of particulate chromite, one or more binders and a reductant, in the form of SiC Composite alone, or preferably, SiC Composite in combination with another reductant such as coke, anthracite and/or coal or a mixture thereof; Forming the mixture into agglomerates, typically briquettes or pellets; and heating the agglomerates to a temperature from 800°C to below 1600°C to form sintered and/or pre-reduced agglomerates.
