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. After the quartz is crushed, it is mixed with water to form a slurry. Next, cyanide is added to the slurry to dissolve the gold particles. This process is called leaching. The slurry is then filtered to separate ...
