The METS team has over the last 27 years serviced the resource industry in all regions of the world. Our team has a broad range of services within the area of mineral processing from scoping studies, designing test programs, all levels of engineering study through to project commissioning and optimisation of operations.
Starting with your initial enquiry, a senior member of the METS team will advise you on the innovative solutions to your project’s challenging process problems. We will always involve you in the decision making process with clear and concise fee proposals at every stage of your project. We value regular communication and provide you with written project status reports to ensure you are fully briefed on the progress of your project.
It is our goal to help our clients achieve greater value from their projects by delivering valued outcomes – fast start up; early revenue generation, enhanced productivity, greater efficiencies. Although the current business conditions pose challenges for many of our clients, we are working alongside each of them to deliver resilience and strength to projects. If you have a project that appears to have stagnated please get in touch with our METS team to discuss further. We are dedicated to helping you achieve success. A testament that is reflected in our nearly 30 year history.
Crucial inputs to flowsheet development are the metallurgical results obtained from testing mineral samples. The result of the metallurgical testwork has a defining influence on all the process units of a mineral processing plan. Testwork is necessary from the plant development phase through to the end of life of the mine. Sighter testwork establishes if the metals can be extracted from the ore easily or if not possible. It is a critical upfront benchmark.
METS provides the management of metallurgical tests from beginning to end. In the various study stages, metallurgical testwork is required to optimise the mineral processing method and guide equipment selection. METS works in close collaboration with laboratories to plan and supervise testwork programs on behalf of clients. The supervision of the program enables a proactive evaluation of the testwork results and on-the-fly adjustment to the testplan, if necessary. METS has accumulated considerable experience in planning, conducting and supervising many types of metallurgical testwork.
Testwork Plan Development
METS can develop testwork plans for all commodities. The plan is developed based on the level of study for which the work is to be undertaken from Sighter testwork and conceptual studies through to Feasibility studies.
A program of testwork might include:
- Determining the comminution characteristics of the ore and defining the likely behaviour of the ore in crushing and grinding processes;
- Evaluation of pre-concentration options to reduce the mass of material to be processed;
- Conducting bench scale testwork, especially to determine the relationship between size and mineral liberation;
- Conduct variability testing on samples taken across and through the ore body; and/or
- Generate sufficient data for metallurgical flowsheet preparation for the particular level of study.
The plans indicate all testwork required and sample type and weight requirements are also indicated. In addition, a testwork description is developed – particularly if the testwork requirement is extensive – and issued to the client.
Following the testwork plan development, METS can issue the plan to laboratories for quotation or tender and can make recommendations to the client for the preferred laboratory to do the testwork. METS will then manage the testwork and issue the results and interpretation of those results to the client in the form of a testwork report.
METS will manage the testwork programme and liaise with the laboratory on behalf of the client and collect all results when they are available. We will analyse the results and make interpretations based on the results as to further work or the impact of the results on possible treatment options.
Should the results show that a significant change in direction of the testwork is required; METS will inform the client and have further work approved prior to its commencement.
Interpretation of Results
Interpretation of results and client communications is a critical part of the testwork management process. As results are received from the laboratory they are analysed and issued to the client with interpretations so that the client is fully informed at all times as to the progress of the testwork and the implications of the results on the plant design.
The results are discussed and any requirement to change the testwork programme is brought to the attention of the client so that approval can be obtained for those changes.
Reporting and Presentation of Results
At the conclusion of the testwork programme the results and interpretation of the results are presented in a full report to the client. The report will include all the test results within an appendix as well as discussions on the results as they relate to the project. If desired by the client, a presentation and discussion of the results can also be made in a face to face meeting.
