Chrome

Lumpy chrome ore is evaluated by chromium oxide content, Cr/Fe ratio, gangue chemistry, moisture and calibrated size distribution. The delivered lot requires representative sampling and a clearly stated dry or as-received reporting basis.

Chrome concentrate is a beneficiated fine chromite product whose value depends on Cr2O3, Cr/Fe ratio, silica, phosphorus, sulphur, moisture and particle-size distribution. Agglomeration route and handling constraints should be stated before quotation.

Ferrochrome is specified by chromium and carbon class together with silicon, phosphorus, sulphur, size range and recovery expectations. High-, medium- and low-carbon grades are not interchangeable and must be linked to a producer analysis and lot identity.

Chromium metal is a high-purity alloying material supplied in forms such as flakes, pieces or briquettes. Buyers should define chromium basis, critical impurities, particle or piece size, packaging and the analytical method used for release.
