oct 14, 2019 zimbabwe is expected to become one of the worlds largest lithium exporters. At present, zimbabwes mining industry is dominated by platinum and diamonds, and lithium will become one of the countrys major mining industries soon. In 2013, zimbabwe exported 40.9 million tons of lithium ore products and got $57 million in foreign exchange.magmatic ore deposits may be defined as rocks of igneous origin which can profitably be mined for their constituent chemical elements.for example, the worth of annual global production from magmatic ore deposits exceeded $10 billion in 2001, and dominates or contributes significantly to world supplies of elements representing more than a third of the periodic table.
iron ore iron ore deposits are associated with banded ironstone formations in greenstone belts. the most important deposits with highgrade ore are the buchwa and ripple creek. other significant ironstone deposits include the huge mwanesi deposit west of chivhu and nyuni near masvingo. manyoka, mongula and several similarother deposits include hematite-breccia complex deposits, uranium in iron-oxide cu-au deposits and quartz-pebble conglomerate deposits thorium is mined in conjunction with uranium, so much that estimates of reserves for these elements are made based off of uranium content.

the problem is that gold occurs in many types of deposits, and what indicators work great for one type of deposit dont always work well for another. As an example, in some places the presence of vein quartz on the ground is a valuable indicator, yet have been in places where there is so much vein quartz everywhere that is worthless as an trojan and shangani mines are low-grade komatiite-hosted nickel sulfide deposits associated with ca. 2.7 Ga volcano-sedimentary sequences of the zimbabwe craton. At both mines, nickel sulfide mineralization is present in strongly deformed serpentinite bodies that are enveloped by a complex network of highly sheared, silicified, and
