REVIEW: COMPARISON OF ULTRASONICALLY AIDED ZINC,

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.‪Şafak Gökhan Özkan‬ - ‪Google Scholar‬,6th International Mineral Processing Symposium, 277-281s, 1996. 17: 1996: Effect of ultrasound on bubble-particle interaction in quartz-amine flotation system.
