  • Approaches to optimal aquifer management and intelligent

    situ , , oil reservoir management relates to many scales of representation, yet, this fact has not been taken into account in an organized manner for solving aquifer management problems. Fortunately, the rapid development of aquifer management optimization and control in recent years has laid the foundation for such

  • Biofilm dynamics and EPS production of a thermoacidophilic

     · Bioleaching of metal sulfides represents an interfacial process where biofilm formation is important in the initial steps of this process. In technical applications of bioleaching, such as reactor in the temperature range of 50 up to 90 °C and also in self-heating heaps, thermophilic archaea play an important role and often are the organisms of choice

  • Advanced Materials Research Vol. 825 | p. 9

    Abstract: bio- technology is extensively applied to recover metals from low-grade complex ores in the mining industry, particularly the copper sulfide ores. Understanding the effect of bio- process on the pore structure of packed particle beds is important to enhance the percolation and performances with respect to

  • Analysis of coupled flow-reaction with heat transfer in

    A mathematical model for bioleaching is developed to analyze heat transfer, oxygen flow, target ion distribution and oxidation rate in the . The model equations are solved with Comsol Multiphysics software. Numerical simulation results show the following facts: Concentration of oxygen is relatively high along the boundary of the slope, and low in the center part where

  • Column Extraction of Heavy Metals from Soils Using the

    A possible remediation strategy for metal polluted soils is washing with chelants. Here, we compare the efficiency of batch and column extraction of Cu, Zn, and Pb from three soils using the biodegradable chelant EDDS. A total of 53−80% of Cu was extracted in batch and 18−26% in column extraction. For Zn, the extractability was 16−50% in batch and 20−64% in columns and for Pb 25−52
