The Greenbushes site was reopened in 1966. During the 1970s, exploration in the area revealed a 5km long deposit of pegmatite, containing tin, tantalum and spodumene (source of lithium). Although tantalum was recognised in many of the early tin mines, a market was only created by the 1905 invention of the tantalum filament for electric lights.

Spodumene zone (hanging walls of the main pegmatite) This deposit has been mined almost continuously since tin was first discovered at Greenbushes in 1886. Indeed, Greenbushes is recognized as the longest continuously operated mine in WA. The first phase was tin mining from the 1880s until recent decades.
Bismuth, molybdenum and tin have been won from pegmatite, but this is not yet an important source of these metals. Nomenclature Pegmatites can be classified according to the elements or mineral of interest, for instance "lithian pegmatite" to describe a Li-bearing or Li-mineral bearing pegmatite, or "boron pegmatite" for those containing tourmaline.
Lithium concentrate obtained mainly by the flotation of pegmatites (ore), is pulverized and leached in hot acid, and lithium is precipitated as lithium carbonate (Tahil, 2010). The processing of pegmatites is expensive as compared to that of the brines due to the heating and dissolution steps involved, but the higher metal concentration in pegmatites partly compensates for the cost.

Rarely cassiterite occurs in a form known as wood tin which, as the name suggests, has layers like a section through a tree trunk. Tin ore is deposited primarily in pneumatolytic veins around hydrothermal vents or fissures and in greissen stockworks or pegmatites both associated with granites. Quartz is the most commonly associated gangue mineral.

AMG can recover lithium-bearing materials from the existing and future tailings at its profitable tantalum operations at Mibra, with the ore extraction and crushing costs absorbed by the Tantalum operations.
The tin-bearing pegmatite at Uis lies in a 32 km wide schist belt stretching from Uis to Cape Cross, over a distance of 130 km. Uis is probably the largest tin-bearing pegmatite in the world. The several old mine houses are for sale and many have been sold to retired people from other parts of the country.
The search for suitable raw materials has galvanised many junior mining companies to switch from uranium, gold, nickel or copper to searching for lithium.

The pegmatites at the Uis Tin mine were exclusively mined for tin by open cut and hauled to a process plant for crushing and milling for the extraction of cassiterite (tin concentrate). The mine historically produced 35,400 tonnes of cassiterite concentrate in the mine life which delivered an estimated 20 million tonnes of tailings material on surface (Diehl, 1992).
However, pegmatite lithium deposits have considerably higher lithium concentrations than brines, so deposits with extremely high lithium values may still be economically viable. The production of other metals, such as tin and tantalum, can also help offset costs.

Extraction Process of Pegmatite Minerals Strategic Minerals, such as uraninite, garnet, monazite, zircon, cassiterite, columbite, magnetite , are often found closely associated with pegmatic orebodies.
In contrast to salar brine sources, extraction of lithium from spodumene and other minerals requires a wide range of hydrometallurgical processes. Galaxy Resources , which mines spodumene mined in Australia, for example, first crushes and heats the ore in a rotary calcining kiln in order to convert the lithium crystal phase from alpha to beta (a process referred to as decrepitation ).
presence of lithium mineralisation in pegmatites extending along strike for more than 13 kilometres. Assay results from trenching only include intervals of 29m @ 1.54% Li2O and 38m @ 1.29% Li2O in relatively unweathered pegmatite and 197m at 0.50% Li2O in predominantly weathered pegmatite. Further results are awaited.
Lithium comes from two very different types of deposits. It is mined from pegmatite and recovered from the mineral spodumene, and to lesser extent, amblygonite, lepidolite and petalite, mainly from deposits in the USA, Canada and China. Lake brines and playa evaporites also contain lithium; USA and Chile are important sources.
Lithium Australia believes the key to success is beneficiating the lithium clay deposits to produce a feed grade capable of supporting the cost of subsequent lithium extraction techniques. It is likely that the techniques developed to commercialize the Electra project can be applied to other lithium clay deposits.
Emerging Lithium Producers Across the globe, lithium can be found mainly in pegmatite type deposits and brine deposits, with lithium-bearing brine resources accounting for a large part of the resources.
