However, extracting gold from quartz vein gold ore is a meticulous process that requires careful planning and execution. 1. Cyanide gold extraction includes crushing, leaching, filtering, adsorption, elution, etc. The first step in the method is crushing the quartz into small pieces. This can be done using a jaw crusher or a mortar and pestle.

Hg/CN processing follows common patterns. Mercury amalgamation is typically performed directly by miners and only extracts 20–40 % of gold, leaving the majority in the tailings (Torkaman and Veiga, 2023; Velásquez-López et al., 2011).Miners who perform mercury amalgamation on-site often sell their tailings to off-site plants for …

The average person who is cremated has got up to 13 different fillings. So of course that mercury gets vaporized and if you cremate enough people, you're going to have mercury shifting in the air and being dumped in the water.
