Investigating the Effect of Zero Prewetting Time on Rougher Flotation of Coal Tailings [PDF]
Iranian Journal of Materials Science and Engineering, 2022 The beneficiation of coal tailings is usually difficult by common oily collectors in the flotation process, so it is necessary to use a suitable method for clean coal recovery from coal tailing dams. Thus, this study was aimed to investigate the behavior

Eskişehir Osmangazi Üniversitesi Mühendislik ve Mimarlık Fakültesi Dergisi, 2022 Negatively Biased Flotation Column (NBFC) is a tool, which is developed for the flotation of coarse-sized ores. Unlike the conventional flotation column, in this column, there is no froth zone and wash-water is usually not used.
