DIFFERENT TYPES OF SCREENS USED FOR MINING Hawk

Jul 27, 2015  Mining operations are one of the last pioneering ventures on our planet. They descend through geological strata in search of minerals and ore, leveraging modern scientific principles against hard rock and dirt. The crux of the work is located at the mine face, a rock-breaking zone where workhorse drilling and digging tools dispatch heaps of raw rock into steel-encased grizzly feeders.

Introduction to Mineral Processing

Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility. At this point, the ore is called run-of-mine material because there has been no treatment performed on it. There are three primary types of run-of-mine materials: 1. Run-of-mine consisting of useful materials.
