Mineral Processing

Mineral processing is among BBA’s leading-edge disciplines. Our mineral processing experts participate in all phases of mining projects, from prefeasibility studies to commissioning. Members of our multidisciplinary team pool their expertise, carry out high-tech process simulations and determine the equipment, tools and processes needed to optimize mineral extraction, whether for the production of industrial minerals, precious, ferrous or nonferrous metals. All our decisions are driven by the desire to provide clients with the best return on their investment and the most competitive operating costs, while respecting standards designed to protect the environment as well as the health and safety of workers in the field. BBA is very active in the Canadian mining sector and has also carved out an enviable position for itself on the international stage.
