چکیده

The usage of inefficient techniques in artisanal gold mining is quite common, either to extract the ore or processing it, and related to environmental contamination. This paper analyse the mineral processing of a case study in Peru (San Cristobal) with the aim to improve the gold recovery process and the environmental impact. The process of amalgamation (gold-mercury) has been found as ineffective due to the presence of arsenic, while the particles size is not optimal to obtain the gold. Therefore the processing equipment should be changed to improve the grade recovery. The percentage of liberation particles and particle size distribution analysis are the key to evaluate the performance of the process.
