Research on Mechanisms of Improving Flotation Selectivity of Coal Slime
A high percentage of high-ash fine slime materials can deteriorate flotation selectivity through surface covering. This covering of the surface is one of the issues that need to be addressed for efficient flotation processing of difficult-to-separate and high-ash coals. In this study, we investigated the depression effect of SPP on high-ash fine mud by flotation kinetic …

Slime coatings in froth flotation: A review
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 efficiency has not yet reached a satisfactory level. Particles, flotation reagents, and air bubbles are highly dispersed and interact with each other in a flotation cell.

Investigating the system flotation kinetics of fine chalcopyrite in a
The objective of this paper was to quantify the performance of a novel flotation cell, the REFLUX™ Flotation Cell, using low-grade ores sourced directly from the industry for the first time. Two low-grade chalcopyrite ores were studied, both containing about 1 wt% copper, and one being slower floating due to the surface-active slime component.
