Effect of grinding time on flotation of slag 3.2.3. Effect of collector amount In order to see the effect of collector amount on the flotation, experiments were carried out

The Copper Zinc Process Flowsheet After extensive laboratory test work the above typical flowsheet was developed to meet the requirements for this type of ore. Removal of soluble salts as soon as possible is very important in order not to contaminate fresh mineral surface produced in crushing and grinding.

In these tests, a zinc flotation was also performed to measure the metallurgical performance of that metal. The flowsheet schematic and summary of test results. As shown in the summary tables, copper was, on average, 63% recovered into the …

Orica's aim is to continually reduce the number of injuries and other adverse SH&E incidents. The table below summarises the classification of substances that flotation chemicals are divided …

Recent advances in cyanide recovery and producing saleable copper products have changed the flowsheets available for such problematic ores. There are a number of technologies and new …

For the high-Cu ore, the challenge was to produce three distinct Cu, Pb, and Zn concentrates. Whilst the initial approach of exploiting relative flotation kinetics using the current RPZC operating conditions did not achieve the desired Cu-Pb selectivity, a feasible flowsheet was developed based on a modified Black Mountain (Cu-Pb-Zn concentrator) processing route for …

The flowsheet in this study was designed to treat 500 tons per day of a complex base metal ore containing gold and silver values. ... A complex sulphide ore of this type requires a high degree of selectivity in the flotation process. The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate ...

The flotation process involves the application of chemical reagents, such as xanthates, dithiophosphates, and hydroxamates, which are toxic and hazardous. The stringent environmental regulations and the need for recycling mineral wastes demand a suitable alternative eco-friendly process. ... Proposed Process Flowsheet for the recovery of Cu ...

The two case studies described in this paper outline the following stages of design: initial benchscale flotation test work to evaluate the orebody, pilot tests using mined ore bulk …

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water …

• Iron oxide hosted copper-gold (IOCG) deposit- chalcocite, bornite and chalcopyrite with additional "gold only" ores • Mining started 2006, process plant commissioned early 2009 • Total reserves currently 69.8Mt with 1.1% Cu and 0.60g/t Au (as at June 2012) • Extension study underway to increase mine life

resources. The flowsheet of processing copper ores is developed for each particular ore, but there are some general trends in the choice of operations, circuits, reagent options, and equipment. The approaches to processing copper ores and choosing reagents are pre-sented in [5–7]. The flotation process is most often used for copper

The liquid flotation reagents such as Aerofloat 15, 25, and 31 are commonly used in conjunction with the xanthates. These reagents possess both promoter and frother properties. When malachite and azurite are present, reagent 425 is often a useful promoter. This reagent was developed especially for the flotation of oxidized copper ores.

A modal examination of the products produced by the copper flotation rougher-scavenger circuit reveal important information regarding the limits to the efficiency of the process, imposed by mineralogy, fragmentation and flotation capacity. Let's discusses various aspects of rougher flotation circuit performance and how to evaluate its results .

This paper proposes an eco-friendly process to synchronously utilise copper slag and ferruginous manganese ore by co-reduction followed by a magnetic-separation process to solve those...

The PLATSOL ® process may also offer a non-cyanide process treatment option for recovery of copper and gold from copper–gold and gold–copper concentrates. Ferron et al. (2002) reported on batch laboratory testing of a copper–gold concentrate and a refractory gold–silver concentrate under PLATSOL ® conditions.

The use of lime for pH control is critical to the process. At Newcrest Telfer Cu-Au mine (Australia), sequential flotation is used, in which pyrite is depressed first (by using lime and cyanide), and re-activated (with CuSO 4) prior to a second flotation stage (Benson et al., 2007). This is due to the unique copper-gold orebody at Telfer, which ...

the copper coarse concentrate is incresed at a high level, and the content of lead and zinc is slightly increased when the fineness is high. Therefore, it is determined that the grinding fineness in the roughing flotation of the copper is 70% -0.074 (mm). Flotation Conditions Tests of Copper Sulfides Tests of Different Copper Collectors.
