The tankcellflotation machine has been applied forprocessing of non-ferrous metal ores in many countries over the world. This machine type has more efficiency compared to the traditional flotation machine, which is commonly used in mineral processing plants in Vietnam. This article presents the design and manufacture results of the tankcell flotation machine of the capacity of 8 m³. The testing results of lead-zinc ore flotation with this equipment in the Cho Dien mine, Bac Kan province were also presented. This is one of the research contents of the National Independent Project "Research, design and manufacture of non-ferrous metal ore by tankcellflotation machine " - code ĐTLĐCN. 09/20, which was performed by the National Institute of Mining - Metallurgy Science and Technology. The results help to improve the criteria of recruitment technology and production efficiency, as well as to contribute to promoting the related industrial innovation, technology innovation, equipment modernization, and technique mastering.
