Recovering inner residual carbon is important for fully utilizing coal gasification fine slag (CGFS) resources. In this study, we adopted a combined gravity-separation and flotation process to efficiently recover residual carbon by considering the characteristics of the CGFS and optimizing the operating factors of the process.

In today's world of environmental strain, wastewater treatment has become a, more or less, conventional application of flotation—as for instance, in the oil, food, or chemical industries, and in potable water treatment. In this paper, different flotation methods (such as ion, adsorbing colloid, and adsorptive flotation, including biosorption) …

This document discusses froth flotation, a process used to selectively separate minerals. Froth flotation works by rendering the surface of valuable minerals hydrophobic so they can attach to air bubbles. The bubbles carry the hydrophobic minerals to the surface, where they can be removed from waste rock.

Flotation process. The flotation performances of different collectors (kerosene, diesel, DEP, WCOC, O 3-WCOC, UV-WCOC) were compared using an XFD-1 L flotation machine. The flotation process was referenced to the Chinese national standard GB/T 4757–2013. Flotation was conducted at a pulp concentration of 60 g/L, impeller …
