Abstract
During my professional career including being a research chemist, process engineer, mining consultant and chief metallurgist, I have had the opportunity to change culture through different types of innovation. Examples include academic research, metallurgical circuit changes and other projects. Recently, ST Equipment and Technology (STET) has developed a processing
system based on triboelectric separation. This dry technology provides the mineral processing industry a means to beneficiate fine materials. In contrast to other electrostatic separation processes that are typically limited to particles greater than 75 μm in size, the triboelectric belt separator is ideally suited for separation of very fine (<1 μm) to moderately coarse (500 μm) particles with very high throughput. The high efficiency multi-stage separation through internal charging/recharging and recycle results in far superior separations that can be achieved with a conventional single-stage free-fall triboelectrostatic
separator. The triboelectric belt separator technology has been used to separate a wide range of materials including mixtures of glassy aluminosilicates/carbon, calcite/quartz, talc/magnesite and barite/quartz and recently food/protein separations. These results along with personal antidotes of innovation and cultural change will be presented.
