Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and thenComminution circuits for gold ore processing - ScienceDirect,01-01-2005· The SAG operator who has not been asked to ‘find a way’ to ‘push ore’ through the SAG mill is rare indeed! As a result, many (if not most) operators view the SAG mill as a restriction in the grinding circuit that must be overcome, instead of a comminution unit operation required to prepare ball-mill feed.(PDF) Gold process mineralogy: Objectives, techniques, and,,Gold process mineralogy: Objectives, techniques, and applications.
