Refinement MIT

Overview. Refinement is the process that mined material undergoes so as to remove all undesirable minerals and separate the desired elements. Because the global issues concerning platinum group elements, radioactive minerals, rare metals, lithium and phosphorus result primarily from a lack of distribution as opposed to a lack of production efficiency, Mission 2016 did not work to improve
