feasibility of fly ash-based composite coagulant for coal washing wastewater treatment

Feasibility of fly ash-based composite coagulant for coal washing wastewater treatment

In this study, several fly ash (FA)-based composite coagulants, leached by hydrochloric acid, were prepared to treat coal washing wastewater. The concentrations of Al 3+ and Fe 2+ /Fe 3+ in the leachates and coagulants were analyzed, and optimal experimental conditions, including coagulant dosage and initial pH, were determined using various analytical techniques (scanning electron microscopy

improving ultrafine low-rank coal flotation using polyacrylamide grafted polyvinylpyrrolidone

Improving ultrafine low-rank coal flotation using polyacrylamide grafted polyvinylpyrrolidone

ABSTRACT The flotation performance of ultrafine particles is affected by many factors, especially surface hydrophobicity and agglomeration behaviors. As a solid waste, ultrafine low-rank coal (ULC) possesses poor hydrophobicity, which caused its poor flotation performance. Hence, the key to the economic recovery of ULC is to improve its hydrophobicity. This research reported a graft copolymer

3.3.2. Characteristics of slime water. The main characteristics of slime water were as follows: high concentration, high content of fine particles, high ash content, many negative charges on the surface of particles. These particles kept stable dispersion in the water due to the repulsion of the homoelectric charge.
