This article reviews the major process flow sheets in practice for the recovery of chromite values from various types of ores and critical issues related to chromite ore beneficiation.
Chromite is an important commercial chromium-bearing mineral. It is an oxide of chromium and iron (FeO, Cr 2 O 3, or FeCr 2 O 4). A complex mineral containing …
The Problem with Chromite Processing. Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are …
In actual production, chrome processing plants often use a variety of beneficiation methods to remove different impurities. The specific chrome ore …
This article reviews the major process flow sheets in practice for the recovery of chromite values from various types of ores and critical issues related to chromite ore beneficiation.
This process generates waste, chromite ore processing residue (COPR) as a solid mud. COPR could contain about 2–10% of total Chromium present in the ore, …
High-alumina chromite, largely from podiform deposits, is used in refractory applications, while iron-rich ores, largely from stratiform deposits, are utilized in metallurgical and …
Chromite recoveries is a major concern particularly in processing of finely disseminated ores due to its inherent complexities. The gravity separation process is the main …
The detailed study of chromite ore beneficiation processes reveals that the opportunities still exist to recover chromite values from the low/sub-grade ores and …
In this process, the chromite suspended in the molten (or sub-molten) alkaline medium is decomposed by oxidation, and then the chromium salt is prepared by separation, filtration, and purification steps.
