Here is a 5TPH Rock Gold Gravity Processing and Recovery Plant. Below is the detailed mining procedure: 1. Loaders or Excavators feed gold ore into the raw ore hopper. 2. The chute feeder under the hopper feeds ores evenly to the primary jaw crusher. The primary jaw crusher crushes big stones to medium size, about 50-80mm.
