reducing the ore to a certain size Crushing plant layout is of vital importance Gold containing rocks are crushed for several reasons Crushing reduces the physical size of large rocks exposing more surface area of rock thus exposing any gold that may be in the rock and increasing the probability of obtaining the gold from the rock by gravity concentration or by leaching with cyanide
