Chromite - an overview | ScienceDirect Topics

It is produced by smelting together chromite ore and quartz. An alternative to this process is to remelt high-carbon ferrochromium with silica and coke. This is a two-stage process and economically less attractive than the direct smelting process. The low carbon content in ferrochrome–silicon is a consequence of a decreased solubility of ...

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.

Ore genesis - Wikipedia

Ore deposits formed by lateral secretion are formed by metamorphic reactions during shearing, which liberate mineral constituents such as quartz, sulfides, gold, carbonates, and oxides from deforming rocks, and focus these constituents into zones of reduced pressure or dilation such as faults. This may occur without much hydrothermal fluid flow ...

COAL BASED DIRECT REDUCTION OF PREOXIDIZED .

A chamber furnace is used to carry out the pre-oxidation of chromite ore. The oxidized chromite ore is prepared by heating the initial chromite ore for 2h isothermally at 900 0C in a chamber furnace. A constant flow rate of 40 lpm air is purged inside the furnace to maintain oxidized atmosphere during the preoxidation stage.
