the effect of grinding fineness on the results of flotation velj, regrinding of basic copper concentrate goes to a fineness of 85 - 90% -0.074 mm. regrinding of the basic copper concentrate is also an important technological process that can contribute to increasing the recovery and copper content in the purified concen-trates. taking into account the estimated stirred milling technology a new concept in fine grindingtypical applications are the regrinding of concentrates (e.g. magnetic, flotation), iron ore tertiary grinding, precious metal ores, and fine grinding for hydrometallurgical processes. particularly with rougher concentrate, re-grinding concentrate flow rates can vary a lot based on ore characteristics and up-stream process conditions. copper extractioncopper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 2729% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite

Advantages of regrinding copper concentrate

copper mineral, extraction of zinc, extraction of copper from firstly, selective collectors floated copper based on the original preferential flotation process; then mixed flotation and regrinding the mixed concentrate, grinding fineness can reach -38 μ m78%. xinhai technical reformation had the advantages of simple process and low production cost; the recovery of copper concentrate was 90.21%; lead and zinc are qualified; lead concentrate had recovery rate of 88.3%. importance of oxidation during regrinding of for example, in newcrests telfer gold mine, in order to increase copper and gold recovery, regrinding of pyrite rougher flotation concentrates followed by cleaner flotation of copper and gold minerals was commissioned in 2012 (burns et al., 2012, seaman et al., 2012). the regrinding process liberates the locked copper and gold minerals from pyrite which are then recovered in the cleaner flotation. copper concentrate regrind at sossego plant using vertical copper concentrate regrind at sossego plant using vertical mill an evaluation on the first years of operation . figure 1. summary of the sossego flowsheet . it was clear from the pilot plant results that the performance of the primary grinding was strongly affected by the amount of critical size in the mill load. (pdf) a novel regrinding circuit to deal with fluctuation in in copper concentrate, size distribution of rougher concentrate, the amount of locked chalcopyrite particles, and regrinding circuit performance affect the efficiency of further scavenger and

regrinding copper concentrate application

copper concentratpper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity effect of regrindingregrinding of the copper rougher-scavenger concentrate from p80=83µm to 32µm in the cleaner feed stream resulted in significant improvements in chalcopyrite liberation from 63 to 90% when observed in two dimensions. copper flotationflotation of copper ores. the concentrate can then be reground and refloated with the production of a high-grade copper concentrate together with a low- grade pyritic tailing suitable for return to the roughing circuit. this method is likely to be less costly than one involving the fine grinding of the whole ore.
