Production of FerroChrome – IspatGuru · The agglomeration processes which are generally used for chromite ores include (i) sintering, (ii) pelletizing, and (iii) briquetting. Also the efficiency of the process for the production of FeCr depends on the type and preconditioning of the feed materials namely (i) preheating, and (ii) prereduction.
Green manufacturing process of chromium compounds · The essence of the green process is that traditional oxidation roasting of chromite ore with sodium carbonate at 1200° C is replaced by continuous liquidphase oxidation of chromite ore in the submolten salt medium at 300° C in a multiphase reactor. BRIEF DESCRIPTION OF THE TRADITIONAL PROCESS
Enrichment Characteristics of Cr in Chromium Slag after Pre · Chromium slag is the waste residue generated by the industrial process of extracting chromium (Cr) from chromite ore. Due to different needs for chromite quality in the target product, the extraction processes for chromium (Cr) are also different, leading to diverse compositions and properties for chromium slag [ 1, 2, 3 ].
