. Due to the use of dirty practices, such as open pit mining and cyanide heap leaching, mining companies generate about 20 tons of toxic waste for every 0.333-ounce gold ring. The waste, usually a gray liquid sludge, is loaded with deadly cyanide and toxic heavy metals. While the list of retailers aligned in their opposition to dirty gold continues to grow, most gold is still quite dirty.
Most of the world's gold is extracted from open pit mines, where huge volumes of land are extracted and processed for trace elements. Earthworks estimates that, to produce enough raw gold to make a single ring, 20 tons of rock and soil are extracted and discarded. Much of this waste contains mercury and cyanide, which are used to extract gold from rock. The resulting erosion clogs streams and rivers and can eventually contaminate marine ecosystems deep below the mine.
Exposing the depths of the earth to air and water also causes chemical reactions that produce sulfuric acid, which can seep into drainage systems. Air quality is also compromised by gold mining, which releases hundreds of tons of elemental mercury into the air every year. Modern industrial gold mining practices, such as well extraction and cyanide heap leaching, generate approximately 20 tons of toxic waste for each gold wedding ring. The waste, usually gray sludge, is loaded with deadly cyanide and toxic heavy metals.
Several countries, such as Indonesia, have banned the use of mercury in gold mining. However, experience has shown that prohibition is ineffective or may even worsen the situation if policy makers do not address the root causes of its use. The No Dirty Gold campaign is based on its “golden rules”, a set of criteria that encourage the metal mining industry to respect human rights and the natural environment. Third-party certification organizations, such as Fairtrade Gold and Fairmined, are working hard to transform the mining industry into an active force for good.
Sediments in the soil of San Francisco Bay are still contaminated with mercury left behind by the 19th century California gold rush. Artisanal and small-scale gold miners pour mercury into ground ore, where it merges with gold flecks to form an amalgam, essentially a ball of mercury and gold. Artisanal or small-scale gold miners are clearing the forest to access the rich gold deposits below. When you buy a gold jewel certified by any of these organizations, you pay a small premium that makes a huge difference in the lives of small-scale miners and their communities, with safe working conditions, fair wages and the protection of the environment of the utmost importance.
Around 15% of global gold production comes from artisanal and small-scale mining in more than 70 countries in Asia, Africa and South America. Most of this gold is still in circulation and more and more jewelers are using this material. This operation eventually led to the discovery of the richest gold and copper vein in the world, which is located near the edge of the park. Many gold mines employ a process known as heap leaching, which includes dripping a cyanide solution through huge piles of ore.
Gold has traditionally been a gift of love and, as expected, jewelry sales increase around Valentine's Day. Therefore, activists see Valentine's Day as an excellent opportunity to educate consumers and stifle the dirty gold trade. In addition, according to Septoff, gold that cannot be attributed to any level of deforestation, air and watershed pollution, and human injuries and deaths is practically non-existent. Schimmer and van Deventer (201) discovered that the soil surrounding the gold waste showed poor microbial activity due to the presence of trace metals.
