Mercury: The New Gold Rush Threatening Suriname Dialogo Chino
On paper, Suriname produced about 32,800 kilograms of gold in 2019, and more than half of it came from artisanal and small-scale mining. Gold accounts for more than 80% of Suriname’s income from exports. Much like in Guyana, Suriname’s gold industry is propped up by a black market for mercury, the toxic metal used in the There are many causes of mining pollution. Some of them include the following: 1. Technological Advancement. Technological advancement has a serious role to play in mining pollution. Before the advent of technology, miners had to resort to conventional methods of extracting mined materials from the ore, and these methods had little to no Causes, Effects and Solutions to Mining Pollution

Contamination of groundwater by potential harmful elements from gold
These contaminants from gold mine tailings, as well as mining activities have caused environmental pollution and impact the health of humans living in the vicinity of such mining activities (Wahl et al., 2013; Wu et al., 2014). The contaminants in gold mine tailings are dispersed into the environment by wind, rainwater runoff and surface waterby Shanna Hanbury on 5 September 2023.

Water-pollution problems caused by mining include acid mine drainage, metal contamination, and increased sediment levels in streams. Sources can include active or abandoned surface and underground mines, processing plants, waste-disposal areas, haulage roads, or tailings ponds.Mining Pollution. There have been many documented instances of environmental pollution caused by mining operations, which are often caused by leakages of mining tailings. Mining tailings are the materials left behind after the economically valuable fraction of material has been extracted. These materials are often stored in The Environmental Problems Caused by Mining Earth.Org
