钶钽铁矿化学分子式：Fe++Ta2O6
钶钽铁矿描述：
1. 钽铌，钶钽铁矿石是主要在刚果东部地区发现的几个矿产资源，是一种钝金属，进行精炼时，钶钽铁矿石变成金属钽，耐热粉末，可以容纳高电荷。
2. 钶钽铁矿石的这些特性使其成为制作电容器关键材料，电容器是控制微型电路板内部的电流的电子元件。钽电容器几乎用在所有的手机、笔记本电脑、寻呼机和许多其他电子产品。最近的科技繁荣发展使得钶钽铁矿石价格一路飙升。

Coltan Designations
Chemical Formula: Fe++Ta2O6
Coltan Description:
a) Columbite-tantalite-coltan for short-is a dull metallic ore found in major quantities in the eastern areas of Congo, When refined, coltan becomes metallic tantalum, a heat-resistant powder that can hold a high electrical charge.
b) These properties make it a vital element in creating capacitors, the electronic elements that control current flow inside miniature circuit boards. Tantalum capacitors are used in almost all cell ohones, laptops, pagers and many other electronics. The recent technology boom caused the price of coltan to skyrocket.
