SisAl Pilot process: new video about sampling

10 May 2022

Samples are taken continuously to study the reduction of silica with aluminium to form silicon. The samples can be taken by using a small sampling cup, or by inserting a cold graphite rod into the melt. Metal and slag will solidify at the rod, and can be knocked off afterwards. You can watch our new video about sampling shot during the tests implemented at Elkem’s premises.
