Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.
Mt. Baker Mining and Metals'' jaw crushers are industrial grade, continuous duty machines. They take large pieces of rock, ore, concrete, or other materials, and crush them down to smaller sizes, for further processing in a ball or hammer mill, or for use in ballast or fill applications. Standard features include:
The purpose of the Stamp Mill is to crush gold bearing rock into sand so that it can be processed. The Stamp Mill is a very simple machine. The flywheel builds momentum to turn the cam. The cam lifts the stamps and then gravity drops them back down at a rate of 40 times per minute. It can process approximately 1 ton of rock per hour.
