Venetia is a conventional open-pit mine. Surface mining is expected to carry on for some 20 years and, as the mine becomes deeper, the feasibility of underground operations are being investigated. The targeted pit floor level was at a depth of 400m. A re-evaluation of the pit design undertaken during 1998 reduced the waste-stripping requirements.
Coals may contain as many as 76 of the 92 naturally occurring elements of the periodic table (); however, most of those elements usually are present in only trace amounts on the order of parts per million.Occasionally, some trace elements may be concentrated in a specific coal bed, which may make that bed a valuable resource for those elements (such as silver, zinc, or germanium) (Finkelman
Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare-earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.
