New technology leads the technological revolution in the field of mineral processing, and the flotation technology will reach the nanometer level

Recently, news came from Liaoning University of Science and Technology, Liaoning University of Science and Technology Distinguished Professor, Cheung Kong Scholars, the state thousands of plans professor, academician workstation beneficiation team leader Dr. Tao Dongping team, 15-year research and development of nano-bubble flotation technology on refractory fine Breakthroughs have been made in the separation and utilization of particles and ultrafine particles.

Nanobubbles are small bubbles that range in size from a few hundred nanometers. A large number of AFM observations and scattered light experiments confirmed that nanobubbles do exist at the interface between liquid and hydrophobic solids. Dr. Tao Dongping pointed out that nanobubbles preferentially generate a natural selectivity on hydrophobic particles, and the collision and adhesion processes are combined into one. They perform traditional flotation techniques from various aspects such as flotation kinetics, fluid mechanics, and interface chemistry. In-depth research, the first to propose the theory of nanobubble flotation, and developed a practical technology that can be used in flotation columns and mechanical agitation flotation machines.

Compared with the traditional flotation technology, the collision probability of fine particles and bubbles is small, the probability of adhesion of coarse particles and bubbles is small, and the probability of falling off is large. Nanobubble flotation can realize the sorting of refractory fine particles and ultrafine particles. Increase mineralization speed, significantly improve flotation recovery and concentrate grade, greatly simplify the beneficiation process, reduce equipment investment, and reduce maintenance and operating costs.

Dr. Tao Dongping emphasized that the “nanobubble” flotation column technology has unparalleled superiority and breakthrough. Nanobubbles can be used as a secondary collector to reduce the amount of chemical collector by about 1/3-1/2; nanobubble generation The mechanism is unique, which can reduce the dosage of foaming agent by more than 1/3. At the same time, it can effectively solve the problem of difficult flotation of coarse particles and fine particles, completely break the technical bottleneck of difficult recovery of tailings, help mining enterprises to achieve cost reduction and efficiency quickly, and the prospect is very broad. . ”

This new technology developed by Dr. Tao Dongping's team has great historical significance for China's mineral processing industry and will lead the technological revolution in the mineral processing industry and the mining industry.

Currently, Dr. Tao Dongping research team is working with Anshan Iron Steel Group Company and other units to work together towards the industrial application of nano-bubble flotation technology as soon as possible.
