  • A new method for the treatment of chromite ore

    22/10/2007· Chromite ore processing residue (COPR), derived from the so-called high-lime processing of chromite ore, contains a significant fraction of a leachable Cr(VI) which is harmful to human being and other organisms. In recent years, the concern over environmental pollution from the waste residue containing Cr(VI) has become a major problem for the chromium chemical industry.

  • Optimisation of metal extraction from chromium ore

    The feasibility of extracting metals from chromium (Cr) ore processing residue (COPR) was investigated. COPR samples collected from four sites in New Jersey, USA (sites A, B, C and D) were mixed with 15% carbon by weight with different percentages of sand to neutralise the basic oxide in COPR and heated under a reducing environment to extract metals.

  • Chromite Ore Processing Residue (COPR): Hazardous

    31/03/2005· Chromite ore processing residue (COPR), which contains hexavalent chromium (Cr 6+) at concentrations typically in the range of thousands of milligrams/kilograms, was deposited over a timeframe of 50 years as fill at a site referred to as SA7 in New Jersey.Significant surface heaving associated with COPR weathering-induced mineralogical expansion has been observed at the site

  • Conversion of Chromium Ore Processing Residue to Chrome Steel

    Conversion of Chromium Ore Processing Residue to Chrome Steel Introduction Chromium played an important role in the industrial development of New Jersey from 1905 to 1971. During that period, chromate (Cr6+) was produced from chromite ore at three facilities in Hudson County, NJ. During the chromate extraction process, varying amounts of lime and soda ash were added and roasted with

  • RISKS TO HEALTH FROM CHROMIUM VI IN CEMENT Brussels, 27

    Singapore have increasingly used slag from iron ore processing as a substitute. This results in lower chromium VI contents in the cement and a decrease of allergic contact dermatitis in Singapore has been reported (Goh and Gan 1996). Efficacy of measures The beneficial consequences of personal protection and reduction of chromium VI in cement are obvious. In several countries like Denmark

  • Chemical and microbial remediation of hexavalent

    15/04/2013· Pollution of chromium in solid waste/residue has been noticed from different sources and sites due to the processing and use. A variety of the wastes is generated from the processing of ore to the end use of chromium. In unpolluted soils, the relatively insoluble and less mobile Cr(III) predominates in the form of hydroxides and oxides and adsorbed onto clay particles, soil organic
