Zimbabwe's mineral exports have doubled to $1.3bn in 2010, according to the latest figures from the country's Chamber of Mines.
Platinum shipments have earned $409m, a third of the revenue and gold exports about $380m, while ferrochrome brought in $134m and coal collected $87.9m, reports the Herald.
Nickel earned $111.2m, palladium $100.6m, chrome exports $56.8m and copper $28.5m.
The coal mining sector received a boost with an investment in the Hwange colliery and developments in the mining space including opening up of the Zimbabwe's coal fields and the approval of over 60 applications for the development of its coal asset.
The increase in Chrome output was achieved due to increased processing at Zimasco and Zimbabwe Alloys.
