Client Need

This project was part of the overall strategy to expand production of ore at the Black Star Open Cut Mine in Mount Isa to replace underground mining at Mount Isa Mines that had concluded in 2005.  An independent 600 metre overland conveyor was installed to feed the Heavy Medium Plant from the Black Star Crushing Plant.  Black Star Mine is one of three mines that feed zinc-lead smelting operations at Xstrata Zinc’s Mount Isa Mine.  This project was a key component in safeguarding the economic viability of Xstrata Zinc’s operations.

Project Description

Mineforce was responsible for the structural and mechanical installation and commissioning, including tie-ins to the Crushing Plant and the Heavy Medium Plant building.
