mercury at gold and silver mining operations. This manual "Controlling Mercury Hazards in Gold Mining: A Best Practices Toolbox," draws upon the experience gained in those visits. objective of the manual is to limit miners''exposures to mercury by sharing information within the mining community on methods of controlling mercury .
In many countries, elemental mercury is used in artisanal and smallscale gold mining. Mercury is mixed with goldcontaining materials, forming a mercurygold 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.

Smallscale gold miners use mercury to extract the gold from the ore. Environmental and health assessments of gold mining areas in Indonesia, Tanzania and Zimbabwe showed a high exposure with inorganic mercury in these gold mining areas, and a negative health impact of the exposure to the miners and the communities.
The artisanal smallscale gold mining (ASGM) sector exposes miners to toxic mercury when they use the chemical to extract gold from ore. However, with the right policies and market incentives, ASGM presents an opportunity to fight mercury use and contamination, protecting miners'' health and the environment at the same time.
Top 10 Safety Hazards In Mining – and how to control them. New article by Ruth Jenkins. See all of Ruth''s highly recommended safety articles here: Sina Solutions.

This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined. Environmental hazards are present during every step of the openpit mining process. Hardrock mining exposes rock that has lain unexposed for geological ...
Historically, mercury was used extensively in placer gold mining in order to form mercurygold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Largescale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and smallscale gold mining (ASGM), often clandestine, gold prospecting.
