Metallurgical Testwork

Transmin has extensive experience in many different kinds of metallurgical testwork programs.

Process development

    • Use standard technology that can be rapidly taken into production.
    • Maximize recovery of pay metals.
    • Achieve a commercial quality concentrates or metals.
    • Minimize operating costs, principally by saving on comminution and reagent consumption.
    • Minimize capital costs, principally by saving on comminution requirements.
    • Keep the flowsheet simple.
    • Minimize the cost of tailings disposal.
    • Develop a low cost environmental management system for hazardous wastes.
    • Ensure that the process will be effective as projected for all mining blends, particularly in the first five years.
    • Recover potential secondary income streams.
    • Review and fortify the site wide water balance.
    • Identify and quantify project risks regularly.
    • Use existing technologies to mitigate critical risks.
