We highlight the inefficiency of whole ore amalgamation practices used by artisanal gold
miners. Cyanide is an alternative to mercury, but cleaner (cyanidation) plants are expensive …

Mercury pollution from artisanal gold mining causes severe environmental and health
problems, especially to operators and people living around the processing facilities. Over …

In this study, the forms of silver occurrence and behaviour during extraction from primary
gold–sulphide deposits in the carboniferous strata of the Arctic zone of Russia are analysed …

Conventional gold leaching from electronic waste requires the use of strong acid and
threatens environment. Alternatively, gold can be extracted from electronic waste by the …

This paper has x-rayed an approach to investigate the crystallite size of thermally deposited
gold nanoparticles on a glass substrate. The mined and beneficiated gold sample was …

Few investigations have focused on the potential uses of artisanal gold (Au) mine tailings,
despite the fact that artisanal gold mining activity contributes to environmental issues such …

There are two major gold recovery methods: the hydrometallurgical technique, which
employs cyanide solutions, and amalgamation method, which involves mercury (Hg). These …

he extraction of gold in any part of the world is left in the hands of artisanal local miners who
do this with the use of mercury which is considered to be a very hazardous chemical to …

Artisanal gold mining significantly contributes to mercury pollution, resulting in severe
environmental and health problems, especially for workers and local communities. The …

The response of Imogbara (Nigeria) gold ore to shaking tabling gravity separation methods
was investigated in this research work. Gold concentration in run-off mines is usually as low …
