Chemical processing of a low grade molybdenite

2013-7-18  The conventional oxidative roasting process, as applied to high grade molybdenite ores (containing ≥54% molybdenum), cannot be applied to low grade sulphide ores/concentrates for a variety of reasons. That is why these ores/concentrates require alternative processing schemes to extract molybdenum metal in a quantitative manner.
