Özdoğu’s copper and molybdenum production concentrates in its subsidiary, Kuze Ege Copper Enterprise Inc., currently Turkey’s only molybdenum concentrate producer. They produce 50,000 tons of copper concentrate and 1,800 tons of molybdenum concentrate annualy.
Mining engineer Volkan Baskan has been working for Özdoğu Construction and Trade for 10 years and is currently the operations manager for its subsidiary, Kuze Ege Copper.
“When we contacted Metso, we already knew we could count on their technologies: we had been very satisfied with the HP6’s performance in our greenfield project for copper ore and molybdenum concentrate production in 2010. So when we expanded our operations in 2012, we naturally returned to Metso to supply another new machine for our crushing installation,” Baskan explains.
The contract signed between Metso and Özdoğu Construction and Trade included basic design and engineering for a primary and secondary crushing and screening plant plus engineering and supply of flotation cells and slurry pumps; the remainder of the mining process is being supplied by other manufacturers.
While Özdoğu had good experiences with Metso’s technology, they had yet to discover Metso’s expert process engineering and service teams and their capabilities in technical analysis and problem solving.
On the road to recovery
Metso’s project management team, headed by Project Manager Daniel Martijena, delivered the primary crushing installation on-time for immediate operation.
However, it was soon discovered that the metallurgic recovery capacity could be increased to almost double. This was good news for Özdoğu, but there was a drawback: the initial concentration process had not been planned for the higher capacity.
