The main methods for selective extraction of limestone, oil shale and phosphate rock have been selective blasting, bulldozer and excavator ripping and cutting by surface miners. Selective crushing has been achieved by axle crusher and separation by jigging. All methods have shown promising results for changing the waste rock balance in the product.
