Three mathematical models (mixed side-pore and profile side-pore diffusion with uniform or distributed pore length) are derived in dimensionless form to simulate the transport of solutes through the flowing channels and the stagnant pores of an unsaturated heap. Model parameters are determined from experimental tracer residence time distributions using the least square minimization approach. It...
Bacterial leaching is the extraction of metals from their ores using microorganisms. The most important player in the bioleaching process is. 4 Bacterial Attachment on Mineral Surfaces 200. 5 Microbial Diversity in Bioleaching Environments 200. Minerals are obtained using a leaching process.greater understanding of the mechanism of bacterial leaching of sulphide minerals. This latter process wh...
Heap leach operations typically employ some form of modelling and forecasting tools to predict cash flow margins and project viability. However, these vary from simple spreadsheets to phenomenological models, with more complex models not commonly employed as they require the greatest amount of time and effort. Yet, accurate production modelling and forecasting are essential for managing product...
Bioelectrochemical systems provide a promising tool for the copper recovery from heap leaching solutions which usually contain low and high iron concentrations. In this study, role of ferrous ion concentrations, external resistance in removal synthetic sulfuric acid by lab-scale Microbial Fuel Cell (MFC) was investigated good results were obtained copper.
