crushed ore is fed into a SAG/Ball mill circuit with a median size of approximately 12,000 microns. Most SAG Mills are operated in closed circuit with a screen. The screen fi lters undersized ore, normally minus ½ inch, to a ball mill discharge sump. The combined mill discharges are pumped to undergo classifi cation, normally via hydrocyclones.

Inserts give golfers this exact feel, therefore insert putters are considered as being softer than milled putters. With advanced technology, the variance between the two has largely diminished due to a process known as "deep milling" that makes for a very soft feel on the milled putters. Deep milling has the effect of allowing less contact ...
