Xstrata Technology will provide three M3000 IsaMills in the regrind circuit of the new concentrator. Each mill will be powered by 1,500kW (2,000hp) motors and will use ceramic media. The new concentrator will be designed to treat 140,000 mt/d of ore in a twoline operation and will initially produce 400,000 mt/y of copper in concentrates. The ...

The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput mills (such as ball mills and rod mills ). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill. [7]

The CryoMill is a cryogenic grinder designed with user safety in mind. The liquid nitrogen flows through the closed system and the user never comes into direct contact with LN 2 which ensures a high degree of operational safety. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly ...

Ye et al. (2010) studied the effect of breakage mechanisms during regrinding on pyrrhotite flotation. They found that pyrrhotite recovery was significantly depressed after regrinding in an Isa Mill representing the stirred mill and in a Magotteaux Mill representing the tumbling mill in the absence of additional amounts of collector and copper ions.

The mill can be fed from one end with the product removed from the other end or, alternatively, the mill can be fed from both ends with the discharge at the centre. The process can be wet or dry but is more commonly carried out wet. Maximum rod length is about 6 to 7 metres, otherwise there is a risk of the rods bowing. The

Changes in metal prices and mine output over recent years have required the Copper Concentrator of Mount Isa Mines to operate at annual tonnage rates varying from million to million tonnes. Several circuit combinations were operated during this period utilising up to two semiautogenous grinding (SAG) mills and up to two ball mills.

The gravityinduced mills, Tower Mills and Vertimills, are more efficient in the particle size range typical of regrind circuits, down to P 80 values of around 2040 μm, and below this limit fluidised mills are more efficient [22]. This is primarily due to the differences in grinding media size [28], since gravityinduced mills require media ...

How it works. Eight consecutive grinding chambers, patented product separator and short residence times means the mill constantly delivers sharp product size distribution without external classification. The IsaMill™ is a closed mill. Slurry travels through the mill in a 'plug' flow pattern through consecutive grinding discs.

To identify whether any alteration of the pyrite surface occurred after the addition of copper ions during regrinding, mill discharges after regrinding were subjected to XPS measurements. Table 3 shows the atomic concentration of O, Fe, S and Cu on pyrite surfaces. Fig. 10, Fig. 11 show Cu 2p and Fe 2p XPS spectra, respectively.

Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.
