Grecian Magnesite S.A. has recently acquired and put in operation a new mobile screening unit, which is used to screen stockpiled fine RoM material, which has been accumulated from past processing periods. These materials have a size distribution mainly -40mm. The mobile unit will remove on site the -4mm fraction. The +4mm fraction will be transported to GM’s stationary processing installations, which are now able to treat fine material down to 4mm. The on site screening of the stockpiles results in lower transportation costs and a substantial increase in the yield and productivity of the downstream beneficiation process.
The stockpiles are present both in Yerakini concession as well as in the concessions of Ormilia and Kastri (total > 40 million tons RoM). The unit started operating in Ormilia region in two shifts per day providing 1.500tpd of screened material. With an additional investment, planned for the end of 2012, the capacity and versatility of the unit is expected to increase significantly.
