Using Retorts to Reduce Mercury Use, Emissions, and Exposures in Artisanal and Small-Scale Gold Mining: A Practical Guide

This document is a practical technical guide on using retorts to reduce mercury use, emissions, and human exposure in artisanal and small-scale gold mining operations, prepared by the Artisanal Gold Council in collaboration with international partners and supported by the United Nations Environment Programme and others. It explains how mercury is used in small-scale mining, major exposure pathways, and the health impacts of mercury, particularly for vulnerable populations. The guide describes retort technology, how it functions, safe use practices, design variations, and precautions to avoid increased exposure.
