McGill University An analysis of sulfide ore deposits from one of the world's richest base-metal mines confirms that oxygen levels were extremely low on Earth 2.7 billion years ago, but also shows that microbes were actively feeding on sulfate in the ocean and influencing seawater chemistry during that geological time period. The research, reported by a team of Canadian and U.S. scientists in Nature Geoscience, provides new insight into how ancient metal-ore deposits can be used to...
The US Drug Watchdog says, "About 140,000 US citizens are recipients of the DePuy Pinnacle metal on metal hip implant, and some experts in Europe are now suggesting a failure rate of 50% for the metal on metal hip implants. We are urging all DePuy Pinnacle metal on metal hip implant recipients to have a simple blood test to see if they have elevated levels of cobalt, or chromium in the blood. If the cobalt, or chromium levels are elevated please call us immediately, and we will do our...
Highlights -- Completion of Phase 2 metallurgical test work to optimize the use of desliming and carbonate rejection flotation, as well as chemical reagent dosages to increase the efficiency of rougher/cleaner Ta/Nb flotation and to finalize the preliminary process flow sheet developed in Phase 1 which formed the basis of the PEA. -- Mineral Resource update underway at AMEC to include results of...
LOS ANGELES, Nov. 29, 2012 /PRNewswire/ -- There will be no more "Made in the USA," with millions of jobs lost if the United States doesn't start mining and stock piling certain strategic metals, according to Alisha A. Ahern, co-director of the Academics & Periodicals Department at American Elements, the global chemical and metals manufacturer which published the list. Today the company released its annual top five Endangered Elements List (EEL) of metals that can upset...

LATROBE, Pa., Nov. 15, 2012 /PRNewswire/ -- Kennametal Inc. (NYSE: KMT) today announced commencement of work to evaluate plans and potential locations for an advanced carbide recycling facility in the United States to serve global markets, while also expanding tungsten-cobalt blended powder operations at its existing facility in Tianjin, China to serve the Asia-Pacific region. Both multiyear projects focus on diversifying Kennametal's tungsten sourcing to balance supplies, costs...
ESA ESA research has helped to develop an aircraft-grade alloy that is twice as light as conventional nickel superalloys while offering equally good properties. The path to creating this alloy required research under all types of gravity. Airlines are always looking for ways to save fuel by cutting down on weight without sacrificing safety. Generally, cutting weight by 1% will save up to 1.5% in fuel. For commercial airlines, this saving quickly adds up, offering cheaper flights and...
MGS and the Butter Lane bakery sell cupcakes to raise funds for breast cancer research. New York, NY (PRWEB) October 19, 2012 To celebrate Breast Cancer Awareness Month, Manhattan Gold & Silver (MGS) is partnering with the Butter Lane bakery to hold a “Cupcakes for Cancer” fundraiser. This year marks the second anniversary of Cupcakes for Cancer. Because of the success and support from the first event, MGS has decided to turn the fundraiser into an annual event. From October...
pur-Absorb Iron fulfills the body’s daily absorbed iron needs with a lower dose of iron. Better iron absorption reduces gastrointestinal side effects from excess dosage. North Andover, MA (PRWEB) October 18, 2012 Nelsons, a 150 year old privately owned company and the UK’s largest manufacturer of natural healthcare products, now offers Spatone® pur-Absorb Iron™, a 100% natural liquid iron supplement. With a clinically proven high absorption rate, pur-Absorb Iron fulfills the...
There's a new contender in the race to find an inexpensive alternative to platinum catalysts for use in hydrogen fuel cells. Brown University chemist Shouheng Sun and his students have developed a new material — a graphene sheet covered by cobalt and cobalt-oxide nanoparticles — that can catalyze the oxygen reduction reaction nearly as well as platinum does and is substantially more durable. The new material "has the best reduction performance of any nonplatinum catalyst," said...

Aluminum (or aluminium) is a soft, lightweight, silvery metal. It is an element in the boron group on the periodic table of elements, with the symbol Al and atomic number 13. On the earth's crust, aluminum is the most abundant metal, and the third most abundant of all elements on the earth's crust, after oxygen and silicon. It accounts for 8% of the weight of the Earth's solid surface. Because aluminum is a highly reactive metal, it doesn't occur in nature in a pure form. Aluminum forms a...
Aurichalcite is a mineral, usually found as a secondary mineral in copper and zinc deposits. Its chemical formula is (Zn,Cu)5(CO3)2(OH)6. The name probably originates from the Greek oreichalchos meaning "mountain copper".
Cadmium is a chemical element in the periodic table that has the symbol Cd and atomic number 48. A relatively rare, soft, bluish-white, toxic transition metal, cadmium occurs with zinc ores and is used largely in batteries. Notable characteristics Cadmium is a soft, malleable, ductile, bluish-white bivalent metal which can be easily cut with a knife. It is similar in many respects to zinc but lends itself to more complex compounds. The most common oxidation state of cadmium is +2,...
Cobalt is a chemical element in the periodic table that has the symbol Co and atomic number 27. Notable characteristics Cobalt is a hard ferromagnetic silver-white element. The Curie temperature is of 1388 K with 1.6~1.7 Bohr magnetons per atom. It is frequently associated with nickel, and both are characteristic ingredients of meteoric iron. Mammals require small amounts of cobalt salts. Cobalt-60, an artificially produced radioactive isotope of cobalt, is an important radioactive...
Copper is a chemical element in the periodic table that has the symbol Cu and atomic number 29. Notable characteristics Copper is a reddish-coloured metal, with a high electrical and thermal conductivity (among pure metals at room temperature, only silver has a higher electrical conductivity). Copper may well be the oldest metal in use, as copper artifacts dating to 8700 BC have been found. Besides being part of various ores, copper can be found in the metallic form (i.e. native copper)...
