Glencore McArthur River Mine
Rougher Flotation Expansion Project
- McArthur River
- Control system configuration project
- I/O Count 250
- Yokogawa control system
Glencore’s McArthur River Mine has expanded their flotation capacity by installing 4 new rougher flotation cells and converting the existing rougher flotation cells to a 7th stage cleaning circuit.
This project aims to provide both increased treatment capacity and improved concentrate grades to meet changing zinc concentrate market. Requirements to incorporate new 4 stage rougher flotation cells, as well as flocculent mixing system.
Project scope
- Revise existing plant wide control logic and operator interfaces.
- Electrical design, including 11KV and serial communications
- Integrate new flocculent mixing equipment into DCS
- Train MRM personnel with new system
- Commission during plant shutdowns, without loss of production
Project highlights
- Yokogawa CS3000 Control System including 6 operator screens in the plant and 3 field control stations (FCS) across the plant
- Brownfields project requiring reverse engineering of existing control logic and recoding of system, one box at a time, without changing plant control logic
- Extensive co-ordination with site engineers and operators to, test, install on limited shutdown and commission
