Artisanal and SmallScale Gold Mining Without Mercury. This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost The best practices for chemical leaching are a combination of preconcentration and mill leaching, as they lead to the least amount of waste, a short processing time

Jun 11, 2020 The introduction of technology and digital solutions to artisanal and small scale miners can help decriminalise the sector which can lead to more transparency on how they work what they produce. This can be done through creating platforms that allow miner registration and productivity tracking. Having a streamlined licensing processes will also
