Supplier: Mipac
03 June, 2019

Improve the stability of the grinding (SAG / Ball Mills) and flotation plant (conventional and Jameson cells), through improved instrumentation and control strategies.

Mipac scope:

  • Design, specification, configuration and commissioning of full plant-wide control system for the upgraded smelter. (ISASMELT and waste heat boiler; oxygen plant; sulphuric acid plant; electric furnace; materials handling area; services and utilities)
  • Development of plant-wide measurement and control standards for the project and upgraded smelter
  • Detailed instrumentation design for the ISASMELT plant and waste heat boiler areas
  • Electrical design and procurement specification for associated low voltage motor control centre
  • Client training in control system configuration and maintenance

Technical highlights:

  • Strong focus on simplicity and reliability for maintenance groups
  • Transfer of knowledge from multiple technology providers into common control system to provide consistent operations interface
  • Fast-tracked project with control system on critical path


  • Reduced project costs through economical project implementation by one group with minimised design group interfaces
  • Efficient and cost-effective ongoing control system maintenance due to commonality of equipment and consistency of design
  • Minimised project risk
  • Cohesive approach to instrument design standards, control system design and configuration
