Areas of expertise:

2020-22 Minerals processing in a 3,0 Mta throughput mill, Garpenberg. I had a regrinding project in sphalerite flotation. Other main minerals were galena and silver minerals.

2013-20 Luikonlahti mill, Mill continuous improvement. Knelson and chalcopyrite regrinding were commissioned in 2016. My role was a process specialist and continued at optimisation. Grinding was modified from two stage to three stage grinding. I was active in cyclone optimization too. Pentlandite was another major mineral in Kylylahti mine ore. 

2008-13 Kittilä mine. I was involved with CIL, pressure zadra and dore bar refining. Neutralisation of acidic liquors from pressure oxidation involved an investment to a higher capacity lime slaker. I was in my post as a recent graduate during commissioning of the Kittilä mill.

All mills I worked had ABB 800xA DCS. I was OSA calibration representative (Courier 5i) in Kittilä and Luikonlahti.
