Sep 01, 2020  1. Introduction. It is well known that molybdenite is an important mineral source to extract molybdenum metal. It is usually associated with other sulphide minerals, such as pyrite, chalcopyrite, galena and sphalerite (Hirajima et al., 2017, Hirajima et al., 2014).Owing to the sharp increase in price of the molybdenum metal, the production of molybdenite concentrate has been attracting more ...
