Microbial Reduction of Lateritic Nickel Ore for Enhanced Recovery of Nickel and Cobalt Through Bio-Hydrometallurgical Route
The present invention relates to a foaming agent composition and a method for recycling useful minerals from ores in a water-bearing ore slurry form by flotation. The foaming agent composition comprises a reaction product of C1-C20 polyhydroxy alkane or C3-C20 polyhydroxy naphthene and propylene oxide or a mixture of the propylene oxide and oxirane.
This work has been done worldwide and has resulted in several pilot plant and commercial scale operations for gold ore bio-oxidation. Bioleaching of gold by metabolic products of microorganisms has received less attention, but also offers opportunities for industrial application, especially if future regulations restrict the use of cyanide.
Microbially enhanced hydrocarbon recovery MEHR mechanisms are expected to be impacted by processes and properties that occur over a wide range of scales, ranging from surface interactions and microbial metabolism at the submicron scale to changes in wettability and pore geometry at the pore scale to geological heterogeneities at the petroleum reservoir scale.
He also received the 2016 SPE international award in Reservoir Description and Dynamics. He is currently director of the Enhanced Oil Recovery consortium in the EMS Energy Institute at Penn State University.

Aug 15, 2020018332Key Terms. ore leaching The process of recovering metals from ores by using a number of different techniques. Microbial ore leaching bioleaching is the process of extracting metals from ores with the use of microorganisms. This method is used to recover many different precious metals like copper, lead, zinc, gold, silver, and nickel.
within the ore come in contact with the organisms. This can be achieved through grinding of the ore fine enough to liberate the constituent mineral phases prior to microbial attack. However, crushing and grinding of ore is a significant capital and operational cost, and energy-inefficient process Benzer, 2005 Bilgili and Scarlett, 2005.
Jan 02, 2012018332Iron ore fines and slimes present in tailing dams can be efficiently agglomerated and stabilized using native microorganisms from an environmental angle. Also, such bioprocess would pave the way for recovery of valuable minerals from wastes and for reharvesting and recirculation of process water. 4. Summary
Feb 06, 2012018332This study aims at studying effect of anaerobic dissimilatory iron III reducing bacterial consortium on different phases of iron present in lateritic nickel ore. Such conversion in lateritic nickel ore are helpful in better recovery of sorbed metal values like Ni and Co by subsequent bioleaching or acid leaching. Here properties of thermally and microbially reduced lateritic nickel ore are ...
The frother composition is used in a process for recovering mineral values from ore by subjecting the ore, in the form of an aqueous pulp, to a flotation process. The frother composition comprises the reaction product of 1 a polyhydroxy C1-20 alkane including cycloalkanes or a mono- or di-saccharide, and 2 propylene oxide or a mixture of propylene oxide and ethylene oxide, with the proviso ...
