REVIEW: COMPARISON OF ULTRASONICALLY AIDED

2021-1-29  Zinc is a key beneficiary of economic development for the developing countries. While the global zinc mine production in 2019 was recorded as 13 million tons, the value of zinc mined in 2019, based on zinc contained in concentrate, was about $2.1 billion. Sphalerite or zinc blende (ZnS), which is the main source of zinc, provides more than 90 % of zinc productions today.

[PDF] Ultrasonic control of the level of the

Topical One of the major problems of controlling the level of ore or moving fluid (slurry) is recording the reflected signal. Due to evident heterogeneity of the reflecting surface, dispersion of an ultrasonic wave greatly attenuates the reflected signal making it difficult to detect it against random noises. In this case, the only way to solve this problem is application of acoustic reflectors.
