Application of microbial enhanced oil recovery (MEOR) technology in WBEPs to solve the poor processability of the weathered ore was proposed. It was found that processability of the microbial‐treated weathered ore was greatly improved.
Methods of Metal Recovery by Microorganisms (2 …
Microbial Recovery of Petroleum: By the conventional technique used in the oil fields, approximately one-third of the oil can be recovered. However, the oil recovery can be enhanced by using solvents, and surfactants. Certain polymers produced by microorganisms (e.g., xanthan gum), when added to oil wells are capable of increasing oil recovery.

An ore or concentrate is either placed in a heap or dump where it is irrigated or a finely milled mineral suspension is placed in a stirred tank where it is vigorously aerated. In general, mineral solubilization processes are exothermic and when tanks are used, cooling is required to keep the processes that function at 40°C at their optimum temperature.

INTRODUCTION. Natural microbial consortia are known to facilitate a wide range of complex tasks such as inter-species biofilm formation that allows microorganisms to persist in inhospitable environments (Keller and Surette, 2006).Syntrophic degradation of complex molecules also allows two species to complete metabolic reactions from which neither species would gain energy without the ...

Microbial leaching methods are being increasingly applied for metal recovery from low-grade ores and concentrates that cannot be processed economically by conventional methods. As is the case with many biotechnological processes such methods may have been used since prehistoric times and probably the Greeks and Romans extracted copper from mine water more than 2000 years ago.
