Feb 13, 2017 Ball Mill Grinding Circuit. Even though many ores require fine grinding for maximum recovery, most ores liberate a large percentage of the minerals during the first pass through the grinding unit. Thus, if the free minerals can be immediately removed from the ball mill classifier circuit, there is little chance for overgrinding.

Our Operation Pogo Mine Alaska

Our Operation Pogo Mine Alaska

ORE PROCESSING. The onsite mill processes up to 3,500 tons of ore daily. Gold is recovered using several unit operations. Once the ore is delivered to the mill, the grinding circuit reduces the ore to a very fine particle size (about half of the size of a grain of table salt). This is the first step in separating the gold from the rest of the rock.

FLOWSHEET DEVELOPMENT FOR GOLD

ore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG 19.3) and most gangue minerals (SG 2 to 3). For gold ores that are amenable to gravity separation, recovery of the coarse,

ore treated was very difficult to mill. In the first two days, the mill experienced numerous power dips (overloads), and on at least seven occasions the feed to the mill had to be completely stopped to grind the mill out. Also, the mill load varied in the range of 125 to 165 tons. These disturbances propagated throughout the milling circuit and ...
