IMPACT OF ULTRASOUND ON COAL DESULFURIZATION AND PROCESS OF BIOLEACHING OF METALS

This paper briefly reviews a range of modern research and methodological literature that explores the impact of ultrasound on solid substrates, water systems and microorganisms. The authors examined various physical-chemical and biological effects occurring in particular in microorganisms as well as in processes, in which they are involved, under the exposure to ultrasound fields of different intensity and frequency. The examples of the use of ultrasound treatment aimed at increasing technological results of coal desulfurization as well as bioleaching of metals are provided.
