Boliden Zinc, Copper, Gold and Silver Mine Mining

Jan 22, 2021· The current mill was commissioned in 1985 and has been progressively modernised since then. In 1990, the copper and zinc flotation circuit was streamlined by adding column flotation cells and reducing the recirculation load to improve zinc recovery. In 1992, a Knelson gravity concentrator was added to each grinding circuit to improve gold recovery.
