Gold is a highly required material for a wide range of personal and industrial applications. The high demand for gold, together with the shortage of natural resources and high pollution potential of wastes generated during mining and ore processing activities led to search for alternative sources of gold. A possible source is represented by mine wastes resulting …
Mining common minerals involves managing a large mass (gangue) associated with moving a significant amount of waste generated during mining. For example, the extraction of coal, lignite, building materials, iron, and rare metals, such as copper, nickel, or gold, require drilling, crushing, handling of piles, ore loading, waste loading, unloading, and hauling (Asif et …
The gold mining industry is thus under unprecedentedly much pressure of environmental protection incurred by the high environmental tax and ... There are mainly two types of novel eco-friendly gold lixiviants. One is the common chemical reagents (see Table 1) such as glycine, N-bromosuccinimide (NBS)/pyridine (Py), etc. The other is synthetic ...
Eco-Friendly Approaches to Gold Extraction In the world of mining, gold extraction has long been synonymous with the use of cyanide. This highly toxic chemical has been a staple in the industry for decades due to its effectiveness in separating gold from ore. However, the environmental impact of cyanide in gold mining cannot be ignored.
Gold (Au) melts at a temperature of 1,064° C (1,947° F). Its relatively high density (19.3 grams per cubic centimetre) has made it amenable to recovery by placer mining and gravity concentration techniques.
An alternative to neutralization is the reuse and valorization of the wastewater. This paper rethinks the gold mining wastewater treatment with an integrated system aimed at recovering water, sulfuric acid, and copper from gold mining wastewater, clearing the path to their reuse in the gold processing circuit.

Chemicals are widely used in the gold mining processes. Every step of mining requires special chemicals for specific purposes. Typical gold mining processes are either hydrometallurgical or pyrometallurgical.
Gold (Au), a precious and chemically inactive metal, occupies an essential position in jewelry, economy, and industrial technology due to its brilliant color, high price, remarkable …
Drilling. Drilling is one of the initial phases in open pit mining, involving the use of diesel-powered drill rigs and generators. The combustion of diesel fuel in these rigs results in the emission of CO 2, methane (CH 4), and nitrous oxide (N 2 O). Although CO 2 is the primary emission, CH 4 and N 2 O have significantly higher global warming potentials despite being …
2.2.2. Typical Metallurgical Reagents Present in Gold Mine Tailings . The chemical reagents used in the metallurgical process of gold beneficiation are similar to those presented for the case of copper; therefore, Table 1 is valid for this case as well. In gold mining, a dilute cyanide solution is poured over the crushed and ground rock.
