METS

Plant Optimisation Print

METS has considerable experience in plant optimisation around the world on a number of projects as a means of increasing profitability and reducing costs. Optimisation is not optional, it is a necessity in mineral processing plants. The small relative outlay compared with the financial benefits is a compelling motivation. The input of considerable experience, fresh ideas, new technology and optimisation of the existing technology can lead to much improved plant performance.

Methodology

An on site plant audit to recommend any possible improvements in plant recovery, operating costs or process cycle times. Looking for improved utilisation of resources, mine to mill concepts, establishing KPI's.

Sampling, plant surveys, data collection (data mining) to use as base case inputs, ore characterisation, equipment details, motor sizes, etc.

Extension of the study to include computer modelling, benchmarking, development of the concepts, alternates, etc. Particular attention to the metallurgical accounting problems associated with reconciling mill feed ore grade and recovery, availability, pump failure problems, sampling and assaying practises, metallurgical treatment problems, equipment failure with no warranty and vendor service problems, bottlenecks in the existing circuit and the possible implementation of new metallurgical concepts that could improve the existing plant operations.

The issue of a comprehensive report that will include the technical process findings plus management responsibility, delegation, job descriptions, occupational health and safety, duty of care, planning day-to-day and long term, document control, verbal and written communication, metallurgical performance, maintenance performance, assay and laboratory service, metallurgical accounting, purchasing, consumable stock control, operating methods, operating method control, training on and off the job, language and cultural problems, plant inspections, monitoring and testing, technical innovation in the plant, outsourcing of functions, weekly and monthly reporting and control, daily and scheduled meetings, corrective and preventative action, handling and storage, accommodation and rosters, plant statistics.

Care would be taken to obtain factual information of how things are being operated in the plant by asking the same question from several people to avoid what is essentially miss information and resist offering solutions and neither confirming nor denying whether the current situation was acceptable.

Advantages

  • Improved recovery and reduced costs
