Gold milling, which is also known as fine grinding, pulverising or comminution, is a grinding process that reduces materials into a powder or finer sized particles. Milling is used to recover the maximum amount of gold from the ore by finely grinding it so that gold particles can be removed through gravity separation and/or chemical extraction.

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.

ROM (run of mine) gold ore is delivered in large haul trucks (190 and 300 ton capacity) to a series of stockpiles where it is segregated based on ore grade, fuel value, and carbonate content. A loader reclaims ore from the different stockpiles and loads it into smaller haul trucks (85ton capacity) to create a uniform blend.
