Freeport-McMoRan (FCX) has developed a new process using carbon adsorption followed by ion exchange or solvent extraction to concentrate rhenium from less than 1 ppm to 15 g/L. The product is compatible as a feed to an existing rhenium processing plant.
The main process of the CIP gold processing plant to extract gold from ore and convert it into pure metal can be divided into 6 steps: crushing, screening, grinding, classification, carbon slurry gold extraction and tailings treatment.
Rhenium also is associated with copper minerals in sedimentary deposits in Armenia, Kazakhstan, Poland, Russia, and Uzbekistan, where ore is processed for copper recovery and the rhenium-bearing residues are recovered at copper smelters.
Rhenium is a silver-white transition metal, and is one of the rarest elements in the Earth's crust. It is primarily obtained as a by-product when processing other ores, primarily molybdenum and copper ores. It is used to create high-temperature superalloys - 70% of the worldwide production goes towards making jet-engine parts - and as a ...
Semantic Scholar extracted view of "Oxidative leaching of a sulfidic flue dust of former copper shale processing with focus on rhenium" by Toni Helbig et al.
It has been producing and processing iron ore from its current facilities in Labrador City, Newfoundland and Labrador since 1962. IOC is operated by Rio Tinto PLC, a world leader in iron ore mining and processing and IOC's majority shareholder (58.7%).
Relatively deep deposits, or those with elongated or irregular shapes are typically mined from underground with deep vertical shafts, declines (sloped tunnels) and levels (horizontal tunnels) (Figures 8.2.1 and 8.2.2). In this …

The term processing and recovery plant is broad to say the least so we are going to give some basic examples of the types of ore processing plants. It is important to understand that each full ...
Mineral Processing. As a commonly used process for copper ore beneficiation, flotation can be used for the separation of copper sulfide and oxidized copper ores. The main process of copper ore flotation is rough as follows: ore crushing and screening → stage grinding stage flotation → concentration and dehydration → copper concentrate.

Diamonds often exist in the form of alluvial and also contain rock ore. Diamond processing plant is a facility used in the mining industry to separate diamonds from surrounding gravel or ore, usually by crushing, washing, screening, dense media and jig separation, magnetic separation, etc.
Materials around a mine site that might contain pyrite include rock outcrops exposed by mining, road-building or construction, waste rock or any rock that was mined but doesn't have enough metal to be considered ore, and tailings from a processing plant.
These types of deposits also have large amounts of identified rhenium resources. The future supply of rhenium is likely to depend largely on the capacity of the specialized processing facilities needed to recover rhenium from molybdenite concentrates.
Dasen provides gold ore CIP CIL processing plant and also equipment manufacturing solution with benefits of ultra low power consumption, easy to use and high output rate.
Molybdenum metal production. Molybdenum metal is produced by hydrogen reduction of pure molybdic oxide or ammonium molybdate. The chemical reduction of pure molybdenum trioxide or ammonium dimolybdate to metal requires two stages because conversion directly to metal releases heat that inhibits the process.
