A 700 kW HIGmill for a copper concentrate regrind appliion at the Kevitsa mine in Finland has been commissioned in February 2015 and is operating successfully; both the copper recovery and the copper grade in the final copper concentrate have been increased significantly, where at the same time the nickel grade in the final copper concentrate has been reduced. Other HIGmillsTM are in ...
The development of ultrafine grinding at Anglo Platinum
It was also realized that regrind mills of ~ 3 5 MW, (ball mill equivalent) capacity could be used for both mainstream and concentrate regrind appliions in these plants without having to use multiples of small units. The opportunity to demonstrate and develop an M 10 000 IsaMill fitted the WLTR project objectives. It was a relatively lowrisk installation, as the project could meet its ...
IsaMill Technology Used in Effecient Grinding Circuits
Concentrate grade targets were reduced to maintain zinc recovery, however plant performance continued to deteriorate to such an extent that by the early 1990's the zinc recovery had decreased from 70% to 50% (Young et al, 1997; Pease et al, 2005; Pease et al, 2006). Significant work was conducted at Mt Isa on projects investigating finer regrinding using conventional ball and tower mill ...
Monazite Sands
The treatment of Korean monazite concentrate using 50% NaOH (w/v) at 170 °C is also reported (Panda et al., 2014). In an alkaline treatment of Egyptian monazite in ball mill autoclaves, grinding, and decomposing of monazite take place simultaneously (AbdelRehim, 2002).
