This toxic, contaminated water kills plants and animals, while also dissolving aluminum and heavy minerals found in clean water ( increasing toxicity level ).

For example; the medium-sized Coburn mineral sands deposit, Western Australia, is 230 million tonnes at 1.1 % heavy minerals, and is 13 km long.
33.
Jacobsville Sandstone's heavy mineral suite is 84 % ilmenite, 4 5 % leucoxene, 4 % garnet, 3 % apatite, 3 % zircon, and 1 % tourmaline.
34.
The heavy mineral sands ore deposits of the titanium ores ilmenite and rutile yield most of the mined zirconium, and therefore also most of the hafnium.
35.
CSLN further argued the diamond mines are dangerous work sites, " open pits of heavy minerals, oil, machinery exhaust, and any other rubbish seeps into ".
36.
The beach sands of the district have concentrations of such heavy minerals as Ilmenite, Rutile, Monosite and Zircon, which offer scope for exploitation for industrial purposes.
37.
However, after a collapse in the price of lead, the heavy mineral traffic for which they were purchased dried up and they were placed in store.
38.
Other deposits are the Permian Bowen basins in Queensland, Eyre Peninsula in South Australia, and an oil shale heavy mineral sand deposit in southern Western Australia.
39.
Deep weathering causes the formation of many secondary and supergene ores & ndash; bauxite, iron ores, saprolitic gold, supergene copper, uranium and heavy minerals in residual accumulations.
40.
Similarities in lithology and heavy mineral suites between the Jacobsville Sandstone and the Bayfield group, a similar sandstone located in northern Wisconsin, suggest they may be correlated.
