Rio Tinto Group Rio Tinto Group is a dual-listed company traded on both the London Stock Exchange where it is a component of the FTSE 100 Index[8] and the Australian Securities Exchange where it is a component of the S&P/ASX 200 index.[9] Formation[edit] Operating history[edit] Following their purchase of the Rio Tinto Mine, the new ownership constructed a number of new processing facilities, innovated new mining techniques, and expanded mining activities.[11] From 1877 to 1891, the Rio Tinto Mine was the world's leading producer of copper.[14] The open-pit Corta Atalaya mine was part of Rio Tinto's original operations in Spain. From 1870 through 1925, the company was inwardly focused on fully exploiting the Rio Tinto Mine, with little attention paid to expansion or exploration activities outside of Spain. Pyrite was a major product of Rio Tinto's first mines. Major mergers and acquisitions[edit] Early acquisitions[edit] Merger with Consolidated Zinc[edit] Recent mergers, acquisitions and events[edit]

Research at BIS The BIS carries out research and analysis to contribute to the understanding of issues of core interest to the central bank community, to assist the organisation of meetings of Governors and other central bank officials and to provide analytical support to the activities of the various Basel-based committees. The BIS also comments on global economic and financial developments and identifies issues that are of common interest to central banks. The research agenda of the BIS is focused on key areas of interest to central banks, such as monetary and financial stability, monetary policy and exchange rates, financial institutions and infrastructure, financial markets, central bank governance, and legal issues. The research by BIS economists finds its way into the BIS research publications found on this website, including BIS Papers, Working Papers and Other publications (a compilation of miscellaneous reports).

Cerna, MINES ParisTech Superconducting magnetic energy storage - Wikipedia, the free en Superconducting Magnetic Energy Storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which has been cryogenically cooled to a temperature below its superconducting critical temperature. A typical SMES system includes three parts: superconducting coil, power conditioning system and cryogenically cooled refrigerator. Once the superconducting coil is charged, the current will not decay and the magnetic energy can be stored indefinitely. Due to the energy requirements of refrigeration and the high cost of superconducting wire, SMES is currently used for short duration energy storage. Advantages over other energy storage methods[edit] Current use[edit] There are several small SMES units available for commercial use and several larger test bed projects. These facilities have also been used to provide grid stability in distribution systems. Calculation of stored energy[edit] Where E = energy measured in joules Cost[edit] Citations
The Global Sawlog & Pulpwood Price Report: Wood Resource Quarterly The Global Sawlog & Pulpwood Price Report Wood Resource Quarterly (WRQ), the source for global wood price data and market information, is now in its 18th year with comprehensive analysis of wood market trends for the international forest industry. Each report is approximately 50 pages in length and includes delivered sawlog prices and pulpwood prices and market information from all major regions of the world, including Europe, North America, South America, Oceania and Asia . The report of approximately 50 pages also provides global indices of wood costs, global wood fiber market commentary, pulp grade fiber costs, and a summary of trade of wood chips around the world each quarter. The key factor determining a company's global cost competitive position remains its raw material base and the cost of available wood resources. Timely knowledge of global wood fiber costs and trends remains a cornerstone for competent internal strategic planning within the forest products industry.
La Société de l'industrie minérale Flywheel energy storage Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the flywheel. Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy are being developed.[1] Since FES can be used to absorb or release electrical energy such devices may sometimes be incorrectly and confusingly described as either mechanical or inertia batteries [2][3] Main components[edit] The main components of a typical flywheel. A typical system consists of a rotor suspended by bearings inside a vacuum chamber to reduce friction, connected to a combination electric motor and electric generator. Physical characteristics[edit] General[edit] .

Recyclage de molybdène | | Globe MetalGlobe Metal Globe Metal est un recycleur de molybdène, également appelé « moly ». La valeur du molybdène est considérablement supérieure à celle de la plupart des autres métaux. Souvent les gens ne connaissent pas la valeur de leurs déchets de molybdène et par conséquent les vendent à moindre prix. Habituellement les récupérateurs locaux n’achètent pas ce type de métal exotique. Lorsque vous nous vendez vos déchets de moly, soyez assuré que vous obtenez le meilleur prix qui soit. Les déchets de molybdène que nous achetons prennent diverses formes, telles que : Déchets solides de molybdèneDéchets de plaques de molybdèneSquelette de molybdènePoudre de molybdène Poussière de molybdèneTournures de molybdèneCopeaux de molybdèneFiltres en molybdène Déchets de molybdène purDéchets de molybdène alliéPulvérisation de molybdène Si vous désirez vendre votre molybdène, demandez-nous quel prix nous offrons avant d’aller consulter ailleurs.
