NEW PROCESS ROUTES FOR THE RECOVERY OF MAGNESITE RUN OF MINE FINES

Exploitable results

The project addresses the issue of the valorization of current waste from magnesite mining constituted by fines below 12 mm. Typically any mining company addresses this sort of issue in order to maximize its productivity and return. One third of what is exploited goes to landfill today. The increase in reserve is hence also an issue. The use of classical techniques used for other minerals has been conducted in parallel with the deployment of more sophisticated techniques like Reticon Camera sorter, an optical separator developed during the study, Interesting results were gained, particularly in terms of improvement in operating costs, as well as product quality and yield, for the recovery of magnesite waste. There is no technological innovation except in improvement in optical sorters, due to the use of the Reticon camera sorter. Process optimization has been conducted via simulation. The exploitation of all results will essentially be done by the exploiter on its mining site. The major gain focused on the increase in reserves via better potential valorization of existing quantities. This potential prolongation of the site activity over a longer period, could theoretically reduce operating costs. The extraction costs should also be reduced by 1/3 (ie the fines are to be extracted anyway). Further internal gains may relate to possible combination of coarse and fine materials possible source of cost reduction in one step of the process on basis of improved yield since the two materials would not have the same mineralization ratio. The indirect gains relate to much better understanding of all process steps by the engineers at the mining site. The use of optimization techniques through simulation could spread rapidly taking in account the major gains that such studies can bring for mining operators. The exploitation of the camera sorter involves going from prototype to industrial stage.
