They are used to automatically adjust grind size, reagent addition rates, and froth depth, to maximize Cu recovery in their rougher and scavenger cells and Cu grade in their cleaner and re-cleaner cells (Chadwick, 2010; Supomo et al., 2008). Freeport's Grasberg concentrator installed 172 …


Probably the most significant area of change in mechanical flotation machine design has been the dramatic increase in machine size. This is typified by the data of Fig. 8, which shows the increase in machine (cell) volume size that has occurred with a commonly used cell manufactured by Wemco.The idea behind this approach is that as machine size increases, both plant capital and operating costs ...


Cominco's Alaskan Triumph. The US$414-million (capital) Red Dog mine opened in 1989 with the likelihood of having the world's best zinc deposit. There were nagging questions, however, particularly surrounding the zinc market, the metallurgy and working in this remote corner of Alaska. Those doubts were justified; six years would pass before ...


achieve. The prefloat circuit was reinstated With the prefloat rougher concentrate being sent straight to final tall. Work on pilot scale using Jameson Cells for one stage preflotation and for preflotztlon cleanmg had been performed over a number of years. A series of pilot tests were conducted Ln 2000 to confinn parameters for engineering design.

The Mount Isa Copper Concentrator was commissioned in 1973. Since commissioning some significant upgrades have been undertaken such as: the replacement of the rod mill/ball mill circuit with AG mills and the subsequent conversion of the AG mills to SAG Mills. the introduction of columns as retreat cleaners in 1987, then reallocated as prefloat cleaners in 1994 and rougher cleaners in 1996. the ...
