Manganese Recovery Using Electrowinning Process Equipped with Ion-Exchange Membrane

Recovery of Cadmium and Cyanide using a Combination of Ion Exchange and Membrane Extraction

A combination of ion exchange and membrane extraction successfully recovered cadmium and cyanide from simulated cadmium-cyanide rinsewaters. The ion exchange loading was most effective at cyanidetocadmium molar ratios of 4:l or less; when the molar ratio exceeded 4:1, cadmiumcyanlde complexes caused a chromatographic displacement of free cyanide from the resin. Cyanide-to-cadmium molar ratios i...

Ion Exchange for Recovery of Precious Metals

ith the rapid rise that has occurred in the prices of precious metals during the past few years, recovery of even minute amounts of theseelements has become of greater interest to metal finishers. Although precious metals are recovered easily from concentrated solutions by reduction and precipitation or electrolysis, solutions containing a few parts per million aredifficult to handle by these m...

Microbial Recovery of Manganese Using Staphylococcus epidermidis

Manganese minerals are widely distributed throughout the globe. The most important industrial uses of Mn are in the manufacture of steel, non-ferrous alloys, carbon-zinc batteries and some chemical reagents. Microbial recovery of manganese from low grade manganese ores using bioleaching was investigated in this paper. A bacterial strain, Staphylococcus epidermidis (MTCC-435) was collected from ...

Removal and Recovery of Toxic Silver Ion Using Deep-Sea Bacterial Generated Biogenic Manganese Oxides

Products containing silver ion (Ag(+)) are widely used, leading to a large amount of Ag(+)-containing waste. The deep-sea manganese-oxidizing bacterium Marinobacter sp. MnI7-9 efficiently oxidizes Mn(2+) to generate biogenic Mn oxide (BMO). The potential of BMO for recovering metal ions by adsorption has been investigated for some ions but not for Ag(+). The main aim of this study was to develo...
