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.
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock ( geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear …
Sections broken process. The basic form of the process open and three sections of three sections of a closed two. Work with broken washing process. When the feeding of the mud (-3mm) of more than 5% to 10% and water content greater than 5% to 8%, should increase in the crushing process Gold Ore washing operations.
