01-10-2015· Accordingly, higher pH levels were adopted for cleaner flotation to enhance selective flotation of copper VS pyrite. Concentrate regrinding to a product size of 80% passing 30 µm is adequate to yield, after three stages of cleaning at pH 11-12, a final concentrate assaying 31% copper.
Recovery Of Pyrite From Copper Tailings By Flotation. The experimental procedure to the kinetics of scavenger cleaner and recleaner flotation was the same used in the kinetics of the rougher flotation except that no flotation reagents were added and mineralized froths were scrapped from the froth layer every other 15 s at the following time intervals 01 15 57 and 710 min to scavenger 01 13 35 ...
The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance....
01-04-2014· Pyrite depression in the cleaner stage plays a critical role in producing a high quality copper flotation product. In copper flotation plants, the current strategy is to maximize the recovery of copper minerals by floating some pyrite at the rougher stage while further rejecting it at the cleaner stage after regrinding ( Wills and Napier-Munn, 2006 ).
15-03-2019· Tailings from an industrial copper slag cleaning milling and flotation circuit have been pre-reduced at low temperatures, well below its melting point, using CH 4-H 2-Ar mixtures with the aim of metallizing its iron oxide component to metallic iron.The treatment carried out at 700–900 °C, with a duration of up to 90 min, indicated a complete transformation of magnetite within the first 30 ...

Flotation Machine. Processing Ability: 0.2–16 m³/min Processed Materials: Non-ferrous metal minerals such as copper, lead, zinc, molybdenum, cobalt, tungsten, antimony etc. Applications: The machine can be used to separate nonferrous metal, ferrous metal, noble metal, nonmetallic mine, chemical material and recycle mine.
01-11-2011· This results in a significant upgrade in copper in the cleaner froth whilst still achieving a high copper recovery. The final flotation concentrate usually contains between 25 and 40% Cu." Alain Kabemba, Flotation Process Specialist at Delkor notes the major trend to treating lower-grade and more finely disseminated ores and lately the re-treatment of tailings.
01-03-2009· Flotation response for copper sulphide composite using PAX as the copper collector. Total PAX and MIBC doses were 14 g/t and 48 g/t, respectively. Download : Download full-size image; Fig. 3. Copper grade–recovery relationship after one additional stage of cleaning for the copper sulphide composite.
01-09-2019· The pyrite flotation in the recleaner stage is faster than in the cleaner stage. The recovery of pyrite at 5 min of flotation is 97.8%, and at 7 min of flotation the maximum estimated recovery of 99.1% is reached.
However, liberated copper sulfides were also lost, supporting the notion of depression via oxide coatings. Residence time calculations for the cleaner flotation bank suggested that the flotation capacity was less than adequate, particularly at high mill throughput rates.
Previous results have shown how con- trolled-potential sulphidization (CPS) can give improved metallurgy during rougher flo- tation of mixed oxide-sulphide copper ores. Results in this paper, using different samples and different equipment, confirm the previous results and extend the application of CPS to cleaner flotation. By using CPS, faster flotation of copper minerals (chalcocite and ...
16-05-2016· Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate.
13-04-2016· Copper Cleaner Flotation. Rougher flotation concentrates are cleaned in a standard "Sub-A" Flotation Machine with cell to cell pulp level control. This arrangement for upgrading concentrates is universal in its acceptance by the ore dressing industry.

Problem: A copper ore initially contains 2.09% Cu. After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio
01-09-2019· 1. Introduction. The concentration of sulfide copper minerals by means of flotation generates large volumes of tailings. It is estimated that one hundred twenty-five tons of tailings are generated per one ton of produced copper, and its generation is on a continuous rise because of the decrease of the copper grades .On the one hand, the tailing is considered an environmental problem …
