Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered secondary resources or future deposits of copper ...

Grinding is used to finish workpieces so that they meet the required surface finish quality. It rids unwanted material from the workpiece, like any rough texture that remains from previous machining applications. Grinding machines or tools use an abrasive wheel to remove metal from the workpiece. When the wheel rotates, it cuts material off the ...
