These processes are crucial for the cleaning process for processing chromium related products Traditional methods for processing chromite ore into chromium salt related products face significant challenges such as high energy consumption large discharge of chromium residue waste liquid and severe environmental pollution
Chromite sand is used as a highly fireproof sharpener for moulds and cores Originally from South Africa The sand is produced by crushing chrome ore and its washing in spiral concentrators subsequent drying dust cleaning screening and sorting as per grain size
Its chromite ore processing residue COPR includes carcinogenic and mutagenic calcium chromate CaCrO 4 which is a significant source of pollution to the ecological environment and health of mankind Zhao et al 2017 Hence the lime based roasting process has been eliminated in 2013 This process is replaced by a cleaner lime free

Chromite ore processing residue COPR is an industrial waste generated during the extraction of Cr VI from chromite ore using the high temperature lime based roasting process [[1] [2] [3]] When COPR undergoes weathering reactions during the deposition process it would release highly toxic and mobile Cr VI due to the destabilization and dissolution of the mineral
In order to improve the chromate salts cleaner production technology a pressure leaching process for chromite ore in 50 wt% KOH solution was studied for the first time and the results were presented in this was found out that the chromium extraction rate increased significantly with the increase of temperature and oxygen partial pressure and the
The ferrochrome industry has been dealing with decreasing chromite ore quality requiring costly and resource intensive beneficiation processes that often trade yield for purity FACOR a leader in chrome ore mining and CFlo a champion of sustainable wet processing solutions have collaborated to improve chrome concentrate production at FACOR
69 chromite ore process residue COPR as a waste [9 12] In chromite ores with less than 70 3 wt% silica the proportion of COPR is much reduced than that in high silica >5 wt% 104 leaching and residue washing In industry the extraction efficiency of water soluble
Our main goal is becoming a global high quality chromite sand producer and service provider The chromite sand in our modern facilities are mainly South Africa chromite industrial applications are casting sands in cores and moulds in steel and iron foundries base material in sliding gate mixes plugging sands in ladles at steelworks chrome
