What does grass-fed beef mean? It's all about what the cattle eat. Grass-fed beef means cattle are raised on a diet of only grass and forage for the entirety of their lives. Cattle are ruminants and grass is their natural diet, so the animals are healthier and the beef ends up extremely nutrient-dense and really delicious as a result.

Rare earth prices are not so easily established as they are not traded on commodity markets, so accurate records of prices are difficult to establish. However, from sources such as Roskill 81 it is possible to establish that dramatic increases in prices, up to 10-fold, have been observed over the decade (2002–2012).

The problem is getting hold of the rare earths that make this possible. More than 85% of the world's supply of rare-earth metals comes from China. …

Neodymium is a rare earth metal and a special material: Combined with iron and boron it creates the currently strongest permanent magnets in the world. They can be produced in various shapes (Exclude discs, blocks, cubes, rings, rods and spheres). Their nickel-copper-nickel coating lends them an appealing silver surface.

In addition, China Rare Earth Holdings Limited trades in rare earth products. The company was formerly known as Yixing Xinwei Holdings Limited and changed its name to China Rare Earth Holdings Limited in May 2000. China Rare Earth Holdings Limited was founded in 1987 and is headquartered in Yixing, the People's Republic of China.

The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly-indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...
