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. ...

Platreef ore is classified as hard to very hard and thus not suitable for semi-autogenous grinding. A multistage crushing and ball-milling circuit is the preferred option. The selected flowsheet has a common 4-million-mt/y, three-stage crushing circuit that feeds two parallel milling-flotation modules, each with a capacity of 2 million mt/y.

fraction. The high-grade fraction is treated through a classic MF2 circuit, with the low grade treated in a MF1 circuit, similar to the Merensky ore. The conversion of the UG2 plant to an open-circuit primary milling operation has led to more efficient milling of the high-grade fraction, and has reduced over-grinding of chromite.

The smaller the transmission lines can be, the smaller the circuit itself. Therefore, if a smaller circuit board size is desirable, a board material with a higher Dk value is the best choice. FR4 features a dielectric constant of about 4.5, which is lower than high-frequency materials' Dk, which usually lies around 6.15 to 11.
