Crushing Plant Flowsheet & Design-Layout

By improved efficiency a decrease in energy consumption per ton of crude milled should be achieved. Further savings resulting from finer crushing are realized in the concentration or mineral recovery phase of a process. These benefits are rather difficult to quantify due to the varying complexities of the concentrators and benefication processes.

Mineral Processing

In the early years, mineral processing was called mineral concentration or mineral engineering in China. It was later named mineral processing or mineral resources processing. In the subject classification in China, mineral processing is a subdiscipline of mining engineering. ... The high-grade nickel matte experiences slow cooling, crushing ...
