Gold in Indonesia. Gold Production in Indonesia.

This mine, which is believed to contain the world's largest gold reserves (67.4 million ounces), is
Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This small-scale form of gold mining has little effect on the body of water, but the large-scale practice of mining gold from ore can have tremendous negative effects on water quality.
Some of the major effects of mining on the environment are as follows: Minerals are the natural resources which play an important role in the economic development of the country. But the extraction and mining of these natural resources leads to some adverse effect on our environment as well.

Adverse mining effects on biodiversity depend a great extent on the nature of the contaminant, the level of concentration at which it can be found in the environment, and the nature of the ecosystem itself. Some species are quite resistant to anthropogenic disturbances, while some others will completely disappear from the contaminated zone.
