Rock Crushing methods and How to recover gold from Ores

Finally once the rock is fully crushed we get to the part about separating out the gold from the crushed rock Often this is accomplished simply by very careful panning Panning is the most suitable method if you only have an amount of rock less than about 15 or 20 pounds On the other hand if you are going to be processing large quantities

Crushing in Mineral Processing

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 resistant plate/surface
