Dr. Zhenghe Xu is among the very few engineers who applied at a molecular level the state-of-the-art instrumentation, such as atomic force microscope (AFM) and zeta potential distribution measurement to study of industrial processes related to mineral processing and oil sands extraction. His fundamental research provided scientific insights into industrial processes, which helped the industries to resolve challenges in fine particle flotation and improve processability of poor oil sand ores. His innovative approach in hydrophobic extraction of coal from coal tailings ponds by waste oil led to licensing of his technology to Energy Pacific. His novel aeration concept in flotation led to great improvements in bitumen recovery and commercialization of column flotation at Suncor Energy, which is being tested by other producers.
