Investigation of molybdenite concentrate roasting in chamber and rotary furnaces

In this study, domestic molybdenum disulfide (MoS2) concentrate was roasted in a chamber furnace and then in a rotary kiln. The behavior of the roasting process was examined in both furnaces, and which type of furnace is more advantageous to use in mass production was investigated. It is theoretically possible to roast in a chamber furnace, but a major problem was observed when the amount of concentrate was increased in the chamber-furnace experiments. The problem was solved by using a rotary kiln. This study improves the understanding of the roasting of  MoS2 concentrate and presents a different perspective to the industry, showing that rotary kilns can also be used for roasting.
