Hard Rock Gold Mining Equipment Definition and Significance of Hard Rock Gold Mining. Hard rock gold mining is a method that involves extracting gold from underground deposits of solid rock, rather than from alluvial deposits (sediments in rivers, streams, or other water bodies). This type of mining requires specialized hard rock gold mining equipment and techniques to access …
Crushing and screening. The original rock gold ore is relatively large, so it needs to be crushed first. The vibrating feeder transports the gold ore by a belt conveyor to a jaw crusher for rough crushing, and then the materials from the coarse jaw crusher are sent to a fine jaw crusher or cone crusher for secondary crushing.
