Risk Assessment of Compressor Gold Mining at

2019-6-6  Compressor mining requires a diver staying inside the hole for at least four hours and depends only on a compressor for his supply of oxygen. The harvested mud with gold ores goes through sluicing and use of mercury to obtain gold. Findings from the assessment showed that the miners do not follow safety measures in mining.
