Health and safety company Boletshe Trading Enterprise, a 100% black owned outfit, states that the gold mining industry may cause health hazards for mineworkers and its surrounding communities, as a result of the short term effects of gold mining exposure.

Production of gold has many negative environmental effects

Sep 21, 2010Production of gold has many negative environmental effects. Some of the byproducts of that degradation process, such as nitrates, may contaminate groundwater, but a bigger issue is that the use of cyanide allows mining companies to go after very low grade ore. That means they end up

Gold extraction

Gold extraction. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques since the mid to late 20th century have generally only been the practice of artisan miners.

Environmental Risks of Mining

Environmental hazards are present during every step of the open pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos like minerals, and metallic dust.
