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.

Wherever mercury-gold amalgamation mining unfolds, alchemical processes abound. They are there as catalytic agents forming amalgams at atomic levels. They are there as cultural agents transforming rocks into cell phones and all kinds of consumer goods. And they are there as ideological agents mutually translating human understandings across whole worlds we describe as the sciences, humanities, and social sciences. These processes, we argue, are made more legible - more readily perceived and conceptualised - by peering through the lens of environmental alchemy, a new critical framework in which we apply the historical use of alchemical terms to investigations of environmental change, and to understand the extraordinary complexity that gold and mercury set in motion when mining entangles nature and culture.

Ancient and medieval alchemical works include several comparisons between the generation and development of metals and those of plants, animals, and living beings. These comparisons could refer to adopt physiological models in the explanation of the natural formation of metals and their artificial transformation, to justify the place occupied by alchemy within the broader study of the natural world, and to stand as metaphorical descriptions of specific alchemical procedures. This article analyses these features by focusing on the relationship between mercury and gold, the latter being the "perfect" metal that constituted both an ambitious goal of alchemical practice and one of its key ingredients. The interrelationship between gold and mercury emerges in complex myths about metallic rivers, in the use of gold-mercury amalgams in ancient technology, and in the discussion that alchemists developed around the enigmatic chrysocolla (literally "gold solder"). These three foci are discussed in relation to a variety of ancient sources - from Aristotle and the Stoics to late antique, Byzantine, and Syriac alchemical texts - to explore the different forms of conceptualising metals as living bodies and the interactions of these models with ancient theories on the formation of metals and the alchemical practices aimed at their transformation.

This article considers the presence and absence of mercury, and why in different social arenas where gold features, mercury can become either pervasive or elusive. To substantiate this argument, the article offers two contrasting examples: (1) presentation strategies at Pacific Seaboard gold rush heritage sites, and (2) the background to the Minamata Bay tragedy and the Minamata Convention's subsequent framing of mercury use in artisanal and small-scale gold mining in the Global South. By unpacking these divergent social histories of mercury use and its consequences, the article identifies the current disconnect between different histories of mercury, and the problematic consequences of this disengagement.
