Mineral Processing Innovation

Sepro has been the source of major innovation in the mineral processing industry for more than 30 years. With a large patent portfolio and a constant drive to create new products and improve processes, our company is founded on excellence within engineering design.

We work along the entire research and development process, from fundamental research, to existing product improvement. Client feedback over the years has provided us with deep insight into the needs of the industry, guiding us in creating solutions that reduce energy use and water demand.

With increased automation and efficiency as our core goals, you can expect a Sepro product to be at the forefront of the industry.

Energy Use

Sepro currently has two R&D projects dedicated to step-change energy reductions in the mineral processing industry. In our efforts to improve energy efficiency and practice conservation, we’re also working on a collaborative microwave project that targets up to 70% energy reduction prior to grinding. One of our early stage projects will result in new grinding technology that targets a 50% energy reduction in the grinding process. Our technologies are complementary and potentially lead to an overall 85% reduction in the energy required for comminution.

Water Demand

The Falcon C and Falcon UF have no water addition, which is unique in gravity concentration devices. The Falcon SB uses half the water compared to competitive gravity concentrators. Currently, we have an R&D project aimed at the elimination of any water addition in the SB concentrator. We also have a microwave project that may also improve the ability to recycle process water by reducing the amount of fines and slimes in downstream processes.

Automation

Sepro’s mineral processing equipment have the option to enable remote equipment monitoring so that Sepro’s technical staff can monitor equipment for process optimization and improved uptime. Our equipment have process modules with integrated control structure to reduce costs and improve process integration. We are investigating the possibility of using general compute resources to have step change reductions in automation cost.

Our Most Innovative Products

Falcon Ultra-Fine Gravity Concentrator

The Falcon UF generates the highest G-force of any gravity concentrator on the market. This exceptionally high force enables selective mineral recovery of particles as fine as three microns. The Falcon UF can recover particles previously thought to be unrecoverable by gravity separation methods.

Sepro Intensive Leach Reactor

The Sepro Intensive Leach Reactor has several innovative features. It uses a specially designed agitation system to improve leach kinetics while keeping wear rates low. It also has a patented in-tank filtration system to generate a clear pregnant solution without the need for secondary filtration or solution polishing. Taken together, the Sepro Leach Reactor’s quick cycle times and integrated filtration mean more gold production in a smaller footprint.

Sepro Blackhawk Cone Crusher

The Sepro Blackhawk Cone Crusher has a number of innovative design elements. First class engineering means up to 50% more crushing energy than similar sized cone crushers. An innovative lock bolt design enables quick liner changeouts. A patented braking system reduces liner wear and dramatically improves safety.
