Rock Crushing methods and How to recover gold from Ores

2014-6-22  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

Chapter 4: Mining waste - SGU

The ore is then removed, crushed and refined using various enrichment methods that extract the desired metal and/or mineral. The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, mining method and the composition and stability of the bedrock. The ratio of waste rock/ore is called stripping ratio ...
