Rhenium Distribution and Behavior in the Salinity Gradient ...

The abundance and distribution of dissolved Re (DRe) were determined in the freshwater part of the Krka River (Croatia), which drains a karst landscape, and in the salinity gradient of its highly stratified estuary. Due to the low DRe concentration, a batch procedure consisting of a pre-concentration step using an anion exchange resin (Dowex) and analysis of DRe in 8 M HNO3 eluate …

Rhenium - USGS

Rhenium is one of the rarest elements in Earth's continental crust; its estimated average crustal abundance is less than 1 part per billion. Rhenium is a metal that has an extremely high melting point and a heat-stable crystalline structure. More than 80 percent of the rhenium consumed in the world is used in high-temperature superalloys, especially those used to make turbine blades for jet ...

Phytomining: New Method for Rhenium Production

Phytomining of rhenium Phytomining is defined as the uptake and preconcen-tration of bioavailable metal species from the environment into the plant biomass in a natural way[9, 10]. Preconditions for rhenium phytomining and production are: • Find locations with rhenium concentration in vegetation of industrial importance.

Locations of Deposits

Locations of minable elements can be determined by the deposits of the associated rocks and minerals which, when deposited in significant and refinable concentrations, are called ores. The location of elements varies based on the minerals of which they are part and the rocks that contain those minerals.

The total sorbed amount of rhenium was 0.20 g/g of the resin. It was then eluted by the corresponding eluent in the concentration range up to about 3.0 mol dm-3. The highest elution efficiency and the most favourable elution profile were found with 3.0 mol dm-3 HNO3. Over 77 % of the sorbed rhenium was found in the first 5 ml of the eluate.
