Gold ore concentration process. The Crushing Sections: The gold ore from the mine site is always with size 0-400mm or 0-600mm after blasting. We use the crushing plant to crush the raw gold ore into 0-8 or 0-10mm. Primary Grinding and Classifying Section: The gold ore with the size 0-8mm or 0-10mm will be fed into the ball mill.
