Trade-off Studies

SAG mills or HPGRs? Mechanical cells or contact cells? AME Ltda recognizes that often the choice can be confusing, or that the bottom line is hard to find. We can provide answers quickly so that the engineering team can get to work. Our team have invented, designed, built, or operated many of the newest pieces of equipment to hit the market including:

• Contact cell design and operation (invented)
• Operation of first HPGR application in hard rock copper mining (Cerro Verde)
• Molybdenum pressure oxidation process (invented)
• Column cell design (1st commercial application in copper), fabrication, commissioning, operation.

Our trade-off studies are based on state-of-the-art modeling techniques that are supported by industrial plant benchmarks. Captial costs are derived from our in-house database of up-to-date equipment and installation costs. Operating costs are as per our extensive database of industrial grinding media and energy consumption figures.
