The demolished existing regrind mill will be replaced by a more efficient Outotec Vertimill VTM4500 stirred mill. This will also be in the new building along with new tank cells. Rougher concentrate from all rougher flotation lines will report by gravity to this circuit, where it will be reduced to a P80 of 25 μm.

Vertimill machines help to bring up the fineness of grinding, ie up to 90% of ground materials are minus 33 microns. "Vertimill machines offer a new design. A conventional drum mill operates in the horizontal position, while Vertimill is installed vertically.

Figure 2 – Vertimill grinding and classification zones . Vertimills can be either top fed (the new feed is introduced into the top of the mill via a feed pipe that deposits the feed just above the grinding media), or bottom fed. In the case of Minas Rio, the cyclone underflow is fed by gravity into the bottom of the Vertimills.

To improve grinding efficiency, a ceramic classifying lining was to be developed and tested. In semi-industrial grinding tests with silica sand and limestone, it could be proven that ­energy savings or increases in throughput rates between 5 -25 % can be achieved with the new lining.
