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.
Rutile Mining Process | Equipment | Flow | Cases
Rutile. Rutile is the most common and stable form of titanium dioxide found in nature. It forms under high pressure and high temperature in igneous and metamorphic rocks. It is a key ingredient in paint and also a useful component in optical equipment. Rutile is recovered through surface mining and dredging of dense beach sands.
