Effect of magnetization pretreatment of coal slime water flocculating sedimentation
International Journal of Coal Preparation and Utilization, 2021Sedimentation of coal slime water (CSW) is an important process in coal processing plants. However, CSW is difficult to settle because of its high content of clay minerals and fine particles.

Polyacrylamide (PAM) is widely used as flocculant in coal preparation. A protoplast fusant with enhanced degradation ability of PAM was obtained by intergeneric protoplast fusion between Rhodopseudomonas spheroids and Bacillus subtilis. The protoplast preparation was optimised and inactivation of both parents was performed in different ways.

Coal Preparation Circulating Water Treatment Using Coarse Tail Coal-Slime as Filter Medium
Advanced Materials Research, 2014As the low economic value, many available chemical and physical properties of coarse tail coal-slime used to be ignored. In this paper, coarse tail coal-slime is used as the filer medium for the treatment of circulating water in coal preparation plants.

Promotion of Coal Slime Water Sedimentation and Filtration via Hydrophobic Coagulation
International Journal of Coal Preparation and Utilization, 2018ABSTRACTHighly turbid coal slime water is characterized by high concentrations of fine particles with negative electric charges and a high clay content. These characteristics hinder the sedimentation and dewatering of highly turbid coal slime water. Therefore, we investigated the initial settling velocity, light transmittance, and filter cake moisture ...

The effect of clay slimes on coal flotation, part II: The role of water quality
International Journal of Mineral Processing, 1986Abstract Suspended clay solids, ions, pH and humic acid are shown to have a significant influence on coal flotation. Coal flotation is greater in tap than in distilled water. This is believed due to instability and thinning of the hydrated layer at the surface of the coal particle when ions are present.

AbstractTo determine the effect of different agents on the dynamic characteristics of floc structures, ferric chloride (FC) and anionic polyacrylamide (APAM) were dosed as coagulant and flocculant, respectively, to flocculate the coal slime water. Particle vision and measurement (PVM) was employed to monitor the flocculation process in situ.
