  • Strategies for reducing the environmental impact of reprocessing

    Mercury amalgamation has been the preferred method for gold recovery in Tapajós for centuries. In artisanal mining, due to the low efficiency of gravity concentration and amalgamation, the gold recovery is generally not higher than 30 to 40%, and tailings contain residual mercury (Veiga et al., 2006). Amalgamation is more
