Understanding small-scale gold mining practices: An

We discuss how the technology of small-scale gold mining in the region of Peixoto de Azevedo (Mato Grosso, Brazil) has changed since the early 1980s, giving particular attention to the recent introduction of two main innovations: the mechanized For artisanal and small-scale gold miners, mercury amalgamation provides a simple and inexpensive solution to recover gold. The process entails combining mercury with gold-bearing ore or concentrate. A gold-mercury amalgam is formed, which is heated to vaporize mercury, leaving behind the gold.Mercury and artisanal and small-scale gold mining: Review

At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold The IGR 100 Modular & Portable Small Scale One Man Gold Wash Plant is a self-contained fine gold recovery equipment system.
