In Afghanistan rare metals (lithium, caesium, tantalum and\ud niobium) occur in three main deposit types: pegmatites,\ud mineralised springs and playa-lake sediments (Figure 1).\ud The most potentially significant, easily extractable resources\ud of rare metals in Afghanistan occur in mineralised springs\ud and playas, although there is also considerable potential for\ud exploiting hard-rock pegmatite deposits. Globally, rare metals\ud are produced from deposits in these three settings, chiefly in\ud Chile, Argentina, the USA and Turkey. Lithium has many\ud uses, for example in batteries, in the glass and ceramics industry,\ud and in high performance alloys for aircraft. Most tantalum is used\ud to produce capacitors that are used in laptop computers, mobile\ud phones and digital cameras. Niobium is primarily used in specialist\ud steels although it also shares some uses with tantalum since it has\ud almost identical chemical properties
