The process of gravimetric separation is the foundation of how mineral jigs, like the Mini Max, Riverdance Max, and Pioneer Peak Max, operate. This ingenious process allows for the efficient recovery of gold and other heavy minerals from placer deposits. Let's delve into how it works and why it's so effective. Understanding Gravimetric ...
