Abstract
This paper investigates how the low-temperature roasting of low-grade molybdenite concentrates ([Mo] < 20%) produced at different deposits and the posterior leaching of stubs with soda and alkali affect Mo recovery in a solution. Based on the results obtained, it has been revealed that there do seem to be sufficient reasons for using soda as a selective chemical for leaching stubs; the roasting and leaching modes have been optimized and a processing flowchart of the above concentrates has been proposed. Such a flowchart ensures molybdenum recovery in a solution at 87–97%, depending on the concentrate’s phase composition.
