Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. The expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation.

Environmental Impacts of Gold Mining Earthworks
Gold mining is one of the most destructive industries in the world. It can displace communities, contaminate drinking water, hurt workers, and destroy pristine environments. It pollutes water and land with mercury and Gold has remarkable chemical and physical properties which make it an incredibly useful material despite its high price. Australia’s gold exports generated $25.8 billion in revenue in FY2022. Gold not only spurred Australia’s first mining boom, it triggered the gold rushes of the late 19th century.

Six Ways Gold Mining in Guyana Can Be More Environmentally
Guyana is a mineral-rich state with gold production as its leading economic sector. In 2015, gold accounted for the greatest share of total exports at 42.8 percent of overall exports. The sector directly employs approximately 17–18,000 persons and indirectly benefits 69–70,000 persons. Despite Guyana’s modern regulatory and Miners use heavy mining machinery to drill wide steps known as benches, which separate the rock containing gold (ore) from the rock with no economic quantities of gold (waste). Next, blasting occurs to break down the rock making it easier to move. A fleet of excavators mine designated ore areas and move the gold containing ore to stockpiles.Gold Mining Process

Gold panning
Gold panning, or simply panning, is a form of placer mining and traditional mining that extracts gold from a placer deposit using a pan. The process is one of the simplest ways to extract gold, and is popular with geology enthusiasts especially because of its low cost and relative simplicity. The first recorded instances of placer mining areGold cyanidation (also known as the cyanide process or the MacArthur–Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after Gold cyanidation

Placer mining
Placer mining ( / ˈplæsər /) [1] is the mining of stream bed ( alluvial) deposits for minerals. [2] This may be done by open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which areDrones. Underground mining drones, like Flyability's Elios 3, are used for visual inspections in stopes, ore passes, ventilation shafts, conveyor belts, and other areas of an underground mine.. Drone technology has allowed inspections to be conducted in areas that are unsafe for humans to enter, presenting an invaluable tool in such hazardous conditions.Mining Tools in 2022—A Guide to Mining Equipment and Mining
