Uranium mines pose the added threat of radiation exposure to the list of health concerns.The mining of uranium ores by underground and surface methods produces large and small amounts of bulk waste material.These materials contain naturally occurring radioactive components and become exposed to the environment through mining activities.
In most south african mines, uranium is produced as a by-product of gold mining, which can expose workers to radiation levels higher than the yearly limit of 20 msv a year.Excessive constant noise from machines can cause hearing problems, including deafness, while working underground for long hours with insufficient light can harm vision.
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.
