Amalgamated Histories: Tracing Quicksilver's Legacy Through Environmental and Political Bodies in Andean and Amazonian Gold Mining

Abstract

This article argues that the centuries-long history of mercury-gold amalgamation is crucial to contemporary debates surrounding global mercury pollution from artisanal and small-scale gold mining. Drawing on historical findings that examine Spanish colonial and Indigenous metallurgical knowledge as well as ethnographic and scientific research, we resituate the history of mercury amalgamation in Latin America, focusing on the Colombian Andes and the Peruvian Amazon – two regions where mercury pollution from artisanal and small-scale gold mining provokes international concern. We identify the policy pitfalls caused by overlooking the untold histories of the amalgamation process along with the European contribution to global mercury emissions rooted in these histories. By critically examining the curation of presentist narratives in UNESCO's memorialisation of Almadén's mercury mines as a World Heritage Site, narratives that also underpin initiatives by the United Nations to bring about a “mercury-free world,” we demonstrate how such ahistorical framings contribute to the criminalisation of artisanal and small-scale gold miners, not only in Perú and Colombia but also worldwide. Our findings present an important first step in highlighting the histories of mercury and gold in the hands of artisanal and small-scale gold miners in Latin America.
