In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

The most significant use of mercury was in processing ore from veins of auriferous quartz, which were recognised by the 1860s as the primary source of gold. ... These companies installed reverberatory furnaces and mercury-amalgamating equipment to roast and treat pyritic sands from their own crushing plants, while specialised works processed ...
gold ore; (ii) s mistrust between actors who "own" or control the ore; (iii) inability to control key variables of the testing environment (e.g. differences between mineral processing equipment in use; difficult or not possible to control or test for variables such as grind size, water pressure, flow rates, slurry density, etc.).
At present, there are more than 20 known types of mercury minerals in nature, and the main ones with mining value as industrial raw materials are cinnabar and black cinnabar; Chensha rich ore can be directly smelted in the furnace, while lower grade ore needs to be enriched through beneficiation before entering the smelting process.
technology for the processing of gold-bearing raw materi-als. In the process of performing the work, the following methods were used: gravity recoverable gold test (method of Knelson, Canada), stage test of the Institute Technolo-gies of mineral separation (Russia) (determination of the optimal size of ore grinding and the number of concen-
Cylinder gold amalgamator, also known as cylindrical ball mill, small ball mill, gold mercury mixing machine, alluvial/placer gold mercury mixing machine, gold amalgamation machine, is a kind of internal mercury mixing equipment specially designed for gold ore extraction process. It helps to improve the purity of gold and reduce the waste of valuable mineral resources.
The miners decided to stop using mercury and a follow-up project cleaned their mining equipment for mercury and modified the processing lines. The health care providers were also successfully trained.
Due to the fact that most mined cinnabar contains less than 1 percent mercury, various mineral processing techniques such as jigging, shaking, screening, elutriation, and flotation have been employed to assess the ore. ... Mercury is derived from its primary ore mineral, cinnabar, which is essentially a soft, reddish-brown mercury sulfide. This ...
The Mercury-free mineral processing machine, referred to as "Gold Katcha", is to ensure chemical-free mining without the traditional use of mercury in extracting gold from the ore. The technology has the capacity to recover over 90 percent of gold ore compared to other methods that recover just 30 to 35 per cent of gold.
The President of the Republic, Nana Addo Dankwa Akufo-Addo, has commissioned one hundred (100) mercury-free gold processing equipment, commonly referred to as "Gold Katcha", for use by small ...

In a typical sequential scenario, whole ore or concentrates are first subjected to mercury amalgamation by the miners, either using their own equipment or at a processing center, with 20–40 % recovery of the gold content (Velásquez-López et al., 2011; Torkaman and Veiga, 2023). The amalgamation tailings, now mercury contaminated, are either ...
