Barrick Gold Processing Plant Maintenance Review

Barrick Gold Processing Plant Maintenance Review Location: Zambia, Africa Year: 2018

Project Overview

The Lumwana copper mine is a conventional open pit (truck and shovel) operation. It’s located about 100 kilometers west of Solwezi in Zambia’s Copperbelt, one of the most prospective copper regions in the world. The objectives of this review were to identify key areas of risk and opportunity to enable successful accomplishment of the Life of Mine production plan of processing 25MPTA through the grinding circuit from 2020.

Scope of work

Barrick Lumwana engaged Holistic Asset Management to commence the first stage in their Asset Management Improvement project in Zambia.

HolisticAM conducted a wide-ranging review on the current equipment condition, maintenance processes, practices and performance of the Lumwana process plant to ensure the current life of mine plan could be achieved and further increases in production targets could be safely managed.

HolisticAM mobilised 2 senior asset management consultants during April & May 2018 to conduct the review that required:

  • Review of the critical equipment strategies,
  • Review of critical and insurance spares,
  • Analysis of the existing and past shutdown plans,
  • Analysis and recommendations relating to equipment redundancy,
  • Review of equipment condition and the controls in place for effective management,
  • Review and analysis of equipment performance,
  • Verification and review of equipment strategy deployment,
  • Review of the effectiveness of any equipment change management, and
  • Review of the effectiveness of the management maintenance processes.

It was well understood that the review was designed to provide positive outcomes for the plant performance, condition and the long-term sustainability of the operation. As a result the consultants were very well received at site and received significant support from all stakeholders, asset management and operational employees.
