RT null T1 Creating a Sustainable Artisanal and Small-Scale Gold Mining Sector A1 Biodiversity Research Institute, A1 Global Mercury Partnership, A2 Cordy, Paul K1 mercury PB Paul Cordy and Biodiversity Research Institute YR 2015 FD 2015 LK https://wedocs.unep.org/handle/20.500.11822/11582 UL https://wedocs.unep.org/handle/20.500.11822/11582 NO This document presents a case study in La Segovia, Colombia, where researchers and educators collaborated with miners to improve gold recovery and reduce mercury exposure. It outlines whole-ore amalgamation and unfiltered burning, then describes UNIDO interventions: optimized milling, gravity concentration, managed tank cyanidation, filters and retorts, and formalization contracts with Gran Colombia Gold including safety measures and pensions. Outcomes reported are halved mercury use across 35 centers, expansion of mercury-free capacity, and nearly 50% lower urban mercury vapor despite a 30% rise in gold output.
