Influence of operating parameters on the flotation of apatite
Flotation of apatite is complicated, owing to its physicochemical similarity with other minerals in phosphate ores. Despite this, relatively few studies have been done on the effect of operating parameters, such as the ...
Degradation of humic acids in a microbial film consortium from landfill compost
Bacterial biofilms are ubiquitous in nature and industrial settings. In this study, a biofilm consortium was enriched in a continuous-flow-cell system using humic acid as the sole carbon and energy source. The degradation ...
Effect of ultrasonication on the flotation of talc
The natural hydrophobicity of talc was depressed by the use of ultrasonic treatment during flotation. The recovery of the talc decreased by nearly 30% after 4 min of ultrasonic preconditioning. In addition, two talc ...
Identification of nonlinearities in dynamic process systems
Process modelling is an essential element in the development of advanced (model-based) process control systems, accounting for up to 80% of the cost of development. Often, models based on historic process data are the only ...
Recovery of chromite fines from wastewater streams by column flotation
In the Western Chrome Mine in South Africa, the process water stream contains approximately 3% chromite fines (<100 μm), which report to the tailings dam. This results in resource loss and water contamination. Consequently, ...
Adsorption of heavy metals by biomaterials derived from the marine alga Ecklonia maxima
The adsorption of heavy metals onto biomaterial derived from the marine alga Ecklonia maxima was investigated via batch experiments. The adsorption equilibria of Cu, Pb and Cd could be represented by Langmuir isotherms and ...
