The Strathcona Processing Mill uses four carbon steel thickener tanks where solids and liquids are separated. At the bottoms of these tanks, which measure 100-feet across and 30-feet deep, solid materials are pulled by rotating rakes to an exit point. As the solids settle, liquid overflows into a launder, or trough, to be recycled back to the mill.
