Abstract:
In 2007, Garpenberg mine started Boliden Mines’ first paste backfill operation. From 200,000 t in 2007, the annual paste backfill produced reached 1,000,000 t in 2016. Over the years, several changes have been made in the paste fill plant and the reticulation system to meet the increasing demand on paste backfill. Committed employees with a high degree of freedom to make suggestions and implement improvements have achieved this. Ten years after start-up, or 6 M t of paste backfill later, this paper discusses the present operation and the major changes that have occurred over the years to optimise both the operation and the paste fill quality.
