Artisanal and Small Scale Gold Mining - Zero Mercury

The amount mercury released within ASGM is dependent on the technique applied. The existing techniques include: 1. Whole Ore amalgamation. In this process, mercury is added to all the ore being processes during crushing, grinding and sluicing. This is the most polluting way to use mercury.Using Retorts to Reduce Mercury Use, Emissions, and,,Mercury Use, Emissions, and Exposures in Artisanal and Small-Scale Gold Mining A PRACTICAL GUIDE Version 1.0 One of the purposes of the guide is to help with the implementation of the Minamata Convention obligations as specified in Article 7; Annex C. In particular the guide ad-WHY MERCURY? — Mercury Free Mining Challenge,Mercury has played an essential, if not efficient, role in gold recovery for much of history. While industrial gold operations no longer depend on its use, artisanal and small-scale gold miners (ASGM) remain tied to its use for lack of a healthier, cost effective and more efficient alternative.
