The chromium leachability as a function of magnesium concentration appears to have approximately linear characteristics in the 6- to 20- pct-MgO range examined The dependence of chromium leachability on magnesium content was further supported by a similar plot (fig 8) of the slurry test data from base slags A B C and D

Nov 01 2017This notion is supported by the Health Safety and Environment Guidelines for Chromium report of the ICDA (2007) which states that "hexavalent chromium compounds are found in small amounts in the highly oxidizing fumes from the melting/smelting processes particularly the tapping process" The key to reducing the potential Cr(VI
