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.

The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.
