MINERAL PROCESSING

Particles of different minerals in a rock mass can often be separated from each other by taking advantage of the differences in the physical characteristics (hardness, shape, density, magnetic, electrostatic) or surface chemistry (flotation, settling) of the various constituents. This is usually the first step in the recovery of most valuable minerals into a commercial product. Our laboratories are fully equipped to test your samples from bench scale to demonstration tests with the focus on developing with you a practical and economical flow sheet for your operation whether it is by adapting known technologies to new situations or by developing a new process.
