Design Of A Crushing System That Improves The Crushing :

gold mining, crushing, zimbabwe, jaw crusher, cone crusher 1.0 introduction gold mining is the process of mining gold ores from the ground up till the stage where pure gold is extracted the gold ores are usually big and crushing reduces the physical size of large rocks, exposing more surface area of rock, thus exposingforces are transmitted to the rock, through the bit, and to the cutting surface. the stresses at the contact, as well as underneath the rock, break it. the rock fails in three ways: crushing, chipping, and spalling. the blaster must analyze the mechanics of a drilling system to reveal the limitations and advantages for each type of rock.this instruction guide uses a generic job safety analysis of jobs common to the industry. the jsa format facilitates uniform basic training in safe job procedures, while requiring only a minimum of time and ef fort on the art of the trainer. this mater ial is genericunderground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. soft rock mining refers to excavation of softer minerals such as salt, coal
