In the South Urals, the CuMo ratio of ore decreases eastward along with enrichment in Re. At the same time, molybdenite is depleted in this metal in compliance with more sialic crust and potassium content in ore-bearing dioritic rocks. Quartz diorites at the highest-Re deposits contain 12 wt K 2 O. At most Early-Middle Devonian deposits ...

The geochemistry of rhenium in ores of copper porphyry deposits from various regions has been con sidered in numerous papers presented in the reviews 1-3 and others. We have recently ...
KeywordsRhenium, inductively coupled plasma atomic emission spectral analysis, internal standard, sintering, copper and molybdenum concentrates and ores. Abstract The ICP-AES technique was developed for rhenium determination in the range of 0.00002 - 0.05 in copper and molybdenum ores along with their concentrates.

iii Copper-molybdenum deposits in secondary quartz rocks with rhenium content in molybdenites of 300 to 3000 g t 1. Usually these ores contain only insignificant concentrations of non-radiogenic osmium isotopes. However, they do contain practically pure 187 Os isotope, in the range 99.0 to 99.9 per cent of the total osmium content.
Rhenium and platinum-group metals are recovered from some deposits. Aug233 and others 2005 reported the occurrence of ... The vertical extent of ore is dependent upon the lower copper cutoff grade, which will vary with the price of copper and local mining costs. At Dos Pobres, Arizona, from the top of the orebody to the 0.2 percent copper ...
May 06, 2015018332The distribution of Re in ores of the Mikheevskoe Mo-Cu deposit in the South Urals is studied. It is established that the grade of Re in the ores usually does not exceed 0.5 gt. A positive correlation between concentrations of Re and Mo correlation coefficient 0.94, and Re and Cu correlation coefficient 0.52 is found. EMPA of individual flakes of molybdenite showed that a Re
The commercial source of rhenium is in molybdenite by-product material from porphyry copper ores. Rhenium oxides are driven off upon roasting the molybdenite concentrate. Rhenium is separated ...
Rhenium is obtained almost exclusively as a by-product of the processing of a special type of copper deposit known as a porphyry copper deposit. Specifically, it is obtained from the processing of the mineral molybdenite a molybdenum ore that is found in porphyry copper deposits.
Rhenium is extracted from the host ore molybdenite and porphyry copper deposits. Molybdenite ores are the primary source of rhenium as, typically, molybdenite found in porphyry copper deposits contains about 100 to 3,000 parts per million of Rhenium 2. Rhenium properties. High melting point. Rhenium has a very high melting point, with only ...
Aug 01, 2012018332Rhenium is a unique, valuable and extremely rare chemical element. It is important industrially as high-temperature super alloys and as catalysts for the production of high-octane, lead free gasoline. Rhenium is extracted mainly as a byproduct from the processing of molybdenite associated with porphyry copper ores.
May 01, 2014018332Rhenium is recovered during pyrometallurgical processing of molybdenum sulfide and copper sulfide ores the traditional technology involves removing rheniumVII oxide, Re 2 O 7, from the sulfurous gas phase generated during multiple hearth roasting in molybdenum processing and smelting in copper processing.A new technology platform called Looping Sulfide Oxidation LSO has been
Dec 21, 2012018332Rhenium may be extracted from ores that contain copper and molybdenum. Common practice for leaching copper from low-grade copper ore is to place the ore in a heap leach pad and leach the ore with dilute sulfuric acid solution.

Rhenium. Rhenium produced by KGHM as a by-product in the production of copper. It is obtained from the processing of waste sulfuric acid. More information about rhenium is here. Other products. Refined lead, sulphuric acid, copper sulphate, nickel sulphate and technical selenium are products that KGHM obtains during copper ore processing ...
Nov 07, 2020018332Copper Ore can be found in the overworld at the y-levels between 0 and 80. Approximately 10 ore veins can be found per chunk. As of version 0.27.0, if enabled in the configuration file, it can be found in the Nether, the End, and as of version 0.28.0 a
Rhenium Alloys supplies pure Tungsten, and Tungsten alloys Tungsten-Copper and Tungsten-Rhenium. Tungsten is commonly used in filaments, electric bulbs, electric tubes, heating elements in high-temperature furnaces, high speed tools, and in the aerospace and automotive industries.
Aug 20, 2020018332The Pebble deposit is now estimated to contain 2.6 million kg of rhenium, 57 billion pounds of copper, 71 million ounces of gold, 3.4 billion pounds of
Oct 17, 2019018332Ore Minerals. Copper in these deposits generally occurs in copper-iron sulfide minerals such as chalcopyrite CuFeS 2 and bornite Cu 5 FeS 4. Brassy-yellow Chalcopyrite is the primary copper-bearing mineral in Porphyry deposits. It can be most
There are no known rhenium minerals, and it mainly occurs in molybdenum and beryllium minerals as an impurity. Rhenium is obtained from molybdenite in porphyry copper mines and recovered as a by-product of molybdenum processing. It is mined in the USA, Chile, Canada and Russia.
Ores and ore minerals vary greatly in quality. Ideal ores contain 100 ore minerals. Such ores do not exist, but some come close. Ideal ore minerals contain 100 of the commodity of interest. Native copper, for example, is an ideal copper ore mineral. Ideal ore minerals are, however, uncommon. The most commonly mined ores are not ideal.
