The estimated value of rhenium consumed in 2009 was about $72 million. Recycling: Small amounts of molybdenum-rhenium and tungsten-rhenium scrap have been processed by several companies during the past few years. All spent platinum-rhenium catalysts were recycled.
Pure rhenium is a refractory metal with a very high melting point of 3180°C. Extraction of rhenium from molybdenite concentrates and other primary sources has been studied for many years. Hydrometallurgical methods using Br2, HNO3, Ca(OH)2, NaOH or Na2CO3 have been investigated. Recently, a new process using halogen salts and ammonium as well as oxygen for recovery of …
Rhenium is a very scarce element, occurring in the Earth's crust mainly carried by molybdenite (MoS2). Due to a very low availability comparative to actual industrial demand, rhenium is nowadays one of the most expensive mineral commodities and an increased interest is focused on ex- ploring residues resulting from a long-term mining, particularly of sulphide ore deposits.

Platinum arsenide, sperrylite (PtAs 2), is a major source of platinum associated with nickel ores in the Sudbury Basin deposit in Ontario, Canada. At Platinum, Alaska, about 17,000 kg (550,000 ozt) was mined between 1927 and 1975. The mine ceased operations in 1990.
Rhenium alloys were used in crucibles, electrical contacts, electromagnets, electron tubes and targets, heating elements, ionization gauges, mass spectrographs, metallic coatings, semiconductors, temperature controls, thermocouples, vacuum tubes, and other applications. The estimated value of rhenium consumed in 2009 was about $72 million.
Rhenium is a rare metal with unique properties that make it ideally suited for today's most powerful engines and critical chemical reactions. Eagle Alloys is a premier rhenium metal supplier providing rhenium in both its pure form and most popular alloys.

Jan 08, 2019· American CuMo Mining–more than 260 years of expertise. American CuMo Mining Corporation (CuMoCo) is a Canadian-based mining company directed by industry experts with more than 260 years combined environmental policy, regulation, permitting, compliance, geological exploration, mine planning and sustainable development expertise.
The Engels Mine produced 117 million pounds of copper ore and was the largest copper mine in California. The Pine Creek mine near Bishop in Inyo County produces some copper as a byproduct of tungsten mining. Connecticut. Connecticut is home to the first successful copper mining by Europeans in what is now the United States.
Rhenium is commonly concentrated in Cu–Mo sulfides and tends to be much more abundant in molybdenite than co-existing sulfides. Molybdenite has been shown to be the major host phase for Re in many hydrothermal ore deposits (McCandless et al., 1993). It incorporates Re into its structure at concentrations ranging from some ppb to a few ...
Before the patch I was getting a Rhenium Ore (sometimes 2) of of almost every Guardian of Marr. Logged in this morning and have gotten only 6 of them in 30-40 kills. Also, Bonded Loam was about 1 for every 3 Rhenium and today I haven't even seen 1. _____
Aug 26, 2013· LAS VEGAS--(BUSINESS WIRE)--Mission Mining Company (OTC Pink:MISM) - Mission Mining Company is pleased to report that its potential in-ground Rhenium resources likely make the El Dorado Mine one ...
The occurrence of a REE-enriched mineral does not necessarily correlate with economic feasibility of mining that mineral deposit; mining companies must also look at ore grade of the deposit to determine its profitability. REEs
Rhenium is a by-product of molybdenum, which essentially is a by-product of copper mining. Largest producers: Chile, Kazakhstan and the United States. Uses: Used in high-temperature turbine engines and added to nickel-based superalloys to improve temperature strength.
The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide.
Molybdenite as an Ore of Rhenium. With an average crustal abundance of less than one part per billion, rhenium is one of the rarest elements in Earth's crust.  Most of the world's known rhenium resource exists within the mineral molybdenite, substituting for molybdenum atoms in the mineral's crystal lattice.
Chile has the world's largest rhenium reserves, part of the copper ore deposits, and was the leading producer as of 2005. It was only recently that the first rhenium mineral was found and described (in 1994), a rhenium sulfide mineral (ReS 2) condensing from a fumarole on Kudriavy volcano, Iturup island, in the Kuril Islands.
This data release provides descriptions of more than 100 mining districts, mines, and mineral occurrences (deposits and prospects) within the United States that are reported to contain enrichments of rhenium (Re). These mineral occurrences include mined deposits, exploration prospects, and other occurrences with notable concentrations of rhenium.
Nov 16, 2017· Chile had the most significant rhenium reserves in their copper ore mines and was the top producer as of 2005. The first known rhenium sulfide mineral formed in Kudriavy volcano in Iturp Island Russia in 1994.
An estimated 933,000 troy ounces (ozs) of rhodium were refined worldwide in 2014, a four percent decline in total global production from a year earlier.. The decline in rhodium production was mostly attributable to a long workers strike in South Africa, which involved 70,000 miners and put a halt to work at major platinum group metal (PGM) mines for nearly six months.
7 Rarest Metals Which You Never Heard Of Posted by: Lis Sowerbutts in Commodities In terms of abundance in the Earth's crust, the rarest metals are; gold, platinum, osmium, iridium, palladium, ruthenium, rhodium, tellurium and rhenium.
Apr 24, 2017· Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum. The ore is then concentrated at or near the mine site, to increase the percentage (by weight) of tantalum oxide and niobium.
Some copper-molybdenum and polymetallic ore deposits are rich in elements such as bismuth, tellurium, selenium, gallium, indium, thallium, rhenium and germanium. Armenia also has significant deposits of construction materials, such as granite, basalt, travertine, gypsum, diatomaceous earth, limestone and raw materials for cement production.
