Data collection of rare earth extraction from American coal美国煤炭提取稀土资料汇集

Coal and coal products are also potential sources of rare earth elements. Rare earth elements are a group of elements that most people don't understand (shown in purple in the periodic table below). They include lanthanide elements (CE to L), yttrium and scandium. Although rare elements are very important in our modern technology world, they are quite rare because they are used in various products that people use everyday, including TV sets and mobile phones.

煤炭和煤炭制品也是稀土元素的潜在来源。稀土元素是大多数人所不了解的一组元素（在下面的元素周期表中以紫色显示）。它们包括镧系元素（铈到l），钇和钪。虽然稀有元素在我们的现代技术世界中非常重要，但因为它们被用于人们日常使用的各种产品，包括电视机和手机，所以稀土元素相当罕见。
