The Barrick Osborne concentrator has gone through a number of upgrades . Osborne was seeking a further increase in plant throughput of the order .. copper recovery. Copper in the flotation feed occurs almost completely as chalcopyrite and is very well liberated, even at the relatively coarse P80 utilised, (with only 5.6.
In the mining industry, the plants where flotation is undertaken to concentrate ore are generally known as concentrators or mills. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral.
Mar 19, 2017 . The method and degree of concentration depends on smelter location and schedules, together with the nature of the ore deposit. Sulphide copper ores . Larger plants generally will incorporate a circuit for molybdenum recovery from the copper concentrate by flotation. “Sub- A” Flotation is standard for this.

Abstract: The effects of Z11 and AP407 collectors as well as AF65 and AF70 frothers were evaluated in the rougher flotation circuit of the Sungun copper concentrator plant using 24 full factorial design. Response functions were produced for both Cu grade and recovery and optimized within the experimental range.
In an effort to recover additional copper and gold at KGHM International's Robinson. Mine located near Ruth, Nevada, an in-plant study was undertaken to quantify potential flotation recoveries from the concentrator's final tailings stream. Tests were conducted by passing a small continuous sample of final tailings though a.
Dec 27, 2017 . Full-text (PDF) | In the Katanga province of the Democratic Republic of Congo (DRC), effluents from flotation of oxidised ores of copper and cobalt are stored in settling ponds in view separation of tailings and the mill wastewaters, which . 1.

Mineral processing plant for copper and molybdenum recovery from mine tailings. Client: Astaldi SpA. Location: Tiltil, Santiago, Chile Date: May 2014 – January 2016. The “Minera Valle Aconcaqua” plant was designed to recover, through flotation (pre-concentration and concentration), copper and molybdenum from the.
Chemicals referred to as depressants are added to the pulp to reduce the flotation of the copper minerals while allowing the molybdenum minerals to float. The tailings from the molybdenum plant are the final copper concentrate (typically greater than 30% copper). Following molybdenum rougher flotation and several.

Keynote Lecture: Existing opportunities for increasing metallurgical and energy efficiencies in concentrators . Implementation and optimisation of the SGS MET expert control system at MCM copper flotation plant
Aug 1, 2009 . The highest consumption of water by the concentrator plant is estimated at more than 600 litres/s for milling (a 12.2 m SAG mill and two 8.2 m ball mills) and flotation. Only 10% of the sea water will be desalinated, for human consumption and concentrate washing. Antofagasta is well experienced at using.
