Beyond mercury? ASGM and the shift to gold
When the sustainability of artisanal and smallscale gold mining (ASGM) is discussed, concern over the use of toxic chemical products is often brought to the fore For example, treaties such as the Minamata convention on mercury, programs elaborated by international organizations or NGOs, and actions from national governments try to tackle the widespread use of mercury in processing gold ore The Minister of Finance and Economic Development, Professor Mthuli Ncube, in his delivery note on NDS1 said more gold processing centres will be established, with the aim of empowering every artisanal and smallscale gold miner “Centralised gold service centres will be established during the NDS1 period,” Prof Ncube saidArtisanal miners set sights on increased gold in gold processing; and to establish a mercuryfree gold processing demonstration center in Busia ZIMBABWE In Zimbabwe, the sector of smallscale, artisanal gold mining surpasses that of largescale gold mining Furthermore, 84 % of ASGM activities are unregistered as required by the national Mines and Minerals ActARTISANAL AND SMALL SCALE GOLD MINING AND
