Coal gasification technology is an effective means to achieve clean and efficient utilization of
coal. Coal gasification slag is generated in the process of coal gasification owing to the …

Bubble-particle interaction is of great theoretical and practical importance in flotation.
Significant progress has been achieved over the past years and the process of bubble …

Slime coating is a significant phenomenon in froth flotation. The adverse effects of slime
coating, by which a value mineral is covered by slimes and prevented from direct contact …

Flotation is the main method for recovering and reusing fine low-rank coal by taking
advantage of the difference in physicochemical properties of the mineral surface, but its …

The pristine points of zero charge (PZC) and isoelectric points (IEP) of metal oxides and IEP
of other materials from the recent literature, and a few older results (overlooked in previous …

The purpose of this study was to upgrade the fine slag by a froth flotation kinetics process in
order to separate and recycle the residual carbon and tailing ash simultaneously. Fine slag …

Gasification fine slag is a kind of solid waste, and there is a large number of fine slags need
to be recycled and reused for environmental consideration. The froth flotation kinetics …

During the past years, atomic force microscopy (AFM) has matured to an indispensable tool
to characterize nanomaterials in colloid and interface science. For imaging, a sharp probe …

Coal slurry is an essential component of mining operations, accounting for more than half of
operating costs. Dewatering technology is simultaneously confronted with obstacles and …

Abstract The high carbon content (20–60%) in coal gasification fine ash (CGFA) makes
CGFA unable to be directly used in the building materials and ceramic industries, and can …
