Purification of molybdenite concentrates by a continuous sulfation-leaching process
Wilkomirsky, I.; Becker, J.; Parada, F.
ABSTRACT:
The current processes that aim to purify molybdenite concentrates are not able to dissolve some copper compounds, hence limiting the processes. Typically, the copper content results are from 2 up to 4 weight percent in the last concentrate. Such values are still too high for the molybdenite concentrate to be further processed to molybdenum trioxide by roasting. In order to achieve lower levels of copper — but also avoid excessive molybdenite losses — a continuous sulfation-leaching process is investigated and applied successfully on a pilot scale. Additionally, a reactor prototype and its process parameters are proposed for a commercial plant.
