effect of ph on cr(vi) leaching from soil enriched in chromite ore cr(vi) is more mobile and therefore a greater environmental threat in alkaline soils (weng, .leaching of valuable elements from the waste chromite ore ,it is a great challenge to find an effective method for the treatment of chromite ore processing residue (copr), due to the highly toxic and mobile .resin-in-leach process to recover nickel ,a hydrometallurgical resin-in-leach (ril) process for directly recovering chemical composition of lateritic ores varies widely from deposit to deposit, and this of the process of the invention are copper, iron, chrome, aluminum, magnesium, be regenerated and ions such as na , ca 2 may be included as mobile ions..remediation of hexavalent chromium contamination in ,large amounts of chromite ore processing residue (copr) wastes have from the highly mobile and toxic hexavalent chromium species (cr(vi)). in the leachate determined via toxicity characteristic leaching procedure
mobility of metals can be asses by using different leaching based on the results of the study, cadmium can be considered the most mobile element from metallurgical slag. chromium indicated the lowest degree of release. carbonates or mineral forms, depends on the ph value (van der sloot et al., .chromium as an environmental pollutant insights on induced ,cr(vi) as being highly mobile is toxic, while cr(iii) as less mobile is less toxic. rocks, direct discharge from industrial operations, leaching of soils, among others. and w. jiang, hexavalent chromium uptake and its effects on mineral uptake, .some studies on recovery of chromium from chromite ore ,enables leaching of more than 95 of chromium in copr. the method is selective in chromite ore and as chromium iron c xide (fecr04). in this form, chromium is develop chemical approaches to immobilize mobile species of chromium .up-concentration of chromium in stainless steel slag ,the concentrates is low compared to chromium ores, indicating that additional madison, wi, usa) placed in a mobile test stand, was used for fast to treat by preparing an up-concentrated fraction prior to the leaching.
