In Grecian Magnesite’s operation at Yerakini, northern Greece, the ore is extracted by open pit methods. The process to transform the extracted Run of Mine (RoM) to final products consists of five different main stages: Mining, pre-beneficiation; main beneficiation; calcination/sintering, and; final-processing.

 

Magnesite (MgCO3 - magnesium carbonate) from the Yerakini mine is cryptocrystalline. The material is open-pit mined and transported by own trucks... view more

During pre-beneficiation, the RoM material is crushed, screened at various size fractions and washed. In the primary mineral processing line, the 18-110mm... view more

There are three rotary kilns as well as two shaft kilns with a combined calcination capacity of 550 tpd. Kiln feed magnesite is fired in the kilns to... view more

If required by the customer, caustic calcined magnesia is crushed, ground and classified in different sizes. The final processing plant includes several... view more

Finished products coming either directly from the kilns or from the final processing plant are driven via conveyor belts to the large storage bins. Quality... view more
