Silver Lead Zinc Ore Processing Method using Flotation

Silver Lead Zinc Ore Processing Method using Flotation

The process consists of selective flotation to produce a mixed silver-lead concentrate for maximum smelter return and a separate zinc concentrate. Over-grinding of silver minerals is detrimental to efficient flotation recovery, so the Flash Flotation Unit-Cell is used in the grinding circuit to recover a large part of the silver and lead values .

We mine around 350 ktonnes of zinc in concentrates from our mines in Tara, Garpenberg and the Boliden area every year. The majority of this goes to our zinc smelting plants in Kokkola and Odda, where we produce around 500 ktonnes of zinc every year. They also handle recycled zinc. A large part of our zinc is sold to European sheet metal producers.
