The leaching behavior of hexavalent chromium crvi and major metal elements relevant to crvi leaching from chromite ore processing residue copr to hno3 are investigated by batch leaching tests.According to the test results, aqueous crvi accounted for 70-80 of the content of total cr.Crvi concentration was controlled by the dissolution degree of crvi-bearing minerals such as.
Chromite ore processing procedure.Chromite beneficiation process the problem with chromite processingthe chromite extraction flowsheetchromite process summary experience indicates that chrome ores are concentrated to best advantage by gravity methods.Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be.
Large amounts of chromite ore processing residue copr wastes have been deposited in many countries worldwide, generating significant contamination issues from the highly mobile and toxic hexavalent chromium species crvi.In this study, sodium dithionite na2s2o4 was used to reduce crvi to criii in copr containing high available fe, and then sodium phosphate na3po4.
Chromite ore processing residues copr is the source of the crvi contamination in the environment.Pannonibacter phragmitetus bb was used to treat two different types of coprs in this research.The water-soluble crvi of copr a and b is 3,982.9 and 1,181.4 mgkg, respectively.In the column biotreatment process, p.Phragmitetus bb can reduce crvi in the leachate to an undetectable level.
