7/12/2009· Mining was Zimbabwe's leading industry in 2002, contributing 27% of export trade. The chief minerals were coal, gold, copper, nickel, tin, and clay, and Zimbabwe was a world leader in the production of lithium minerals, chrysotile asbestos, and ferrochromium, with more than half of the world's known chromium reserves.
2 Mineral-Deposit Model for Lithium-Cesium-Tantalum Pegmatites cesium, and tantalum are generally concentrated), and core. This zonation is expressed both in cross section and map view; thus, what may appear to be a common pegmatite may instead be the edge of a mineralized body. Neither lithium-cesium-tantalum pegmatites nor their

Beryllium Extraction Process Flowsheet. Flotation offers the best means for recovering beryl in concentrate form. Much of the flotation technique developed in separation of feldspar from quartz and mica is applicable. In general, beryl will concentrate with the feldspar flotation product. Depressing the feldspar and reflotation of the beryl
15/01/2019· In an ore containing feldspar, quartz and muscovite from Portugal, bromoform was used as dense medium to achieve spodumene recovery of 61.1% with 5.17% Li 2 O (Amarante et al., 1999). Smaller feed size (−4.7 mm) resulted in higher spodumene recovery and grade due to the better degree of spodumene liberation achieved (Amarante et al., 1999).
Tin ore as cassiterite and beryllium ore as beryl also occur in LCT pegmatites, as do a number of gemstones and high-value museum specimens of rare minerals. Individual crystals in LCT pegmatites can be enormous: the largest spodumene was 14 meters long, the largest beryl was 18 meters long, and the largest potassium feldspar was 49 meters long.
