Two BoVac Disc filters L176 are operated in a Gold/Copper Mine in Bulgaria for the filtration of flotation tailings which are used for mine backfill. The dewatered and discharged filter cake is mixed with cement and pumped back to the underground to fill the galleries. For this special appliion the filtered tailings need to have a certain residual moisture to ensure constant conditions for ...
Flotation recovery of copper sulfide from the El Teniente plant has deteriorated in recent years, in this regard ultrasound treatment of tailings for enhanced copper recovery was evaluated in ...
· Many copper tailings have more SiO2 and CaCO3, some FeS2 and another sulfide. 02 tailings reprocessing method (1)Vulcanization flotation of copper tailings. The essence of vulcanization flotation is to sulfide the ground copper oxide pulp .
If grinding is not fine enough for efficient flotation, copper is lost in tailings. In this paper, the ferric leaching of slag flotation tailings is studied. Copper extractions of 66% are achieved ...
Other tailings retreatment options include flotation and smelting, among others. Tailings Reuse. While most work has focused around the recovery of valuable components from tailings, there is also some interest in their reuse for appliions outside of the mining industry.
The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989).
Potential water recovery potentials for copper flotation tailings are shown in the below table. In Chile, current estimates for the cost of desalinated water pumped to the mine are as high as 5 per cubic meter or higher. Table 2: Potential Water Recovery for Dewatering Copper Flotation Tailings [1]
· copper sulfide and free oxidation copper in the raw ore were recycled by flotation, but the other refractory copper oxides, mainly the combination copper oxide, were not thoroughly recycled and the majority were lost in the tailings. As is typical for flotation tailings containing silie gangue minerals, high temperature leaching was used [12].
The present study focused on the reprocessing of copper and nickel from mine tailings. In this work, recovery of copper and nickel from mine tailing by combined process of flotation and high pressure oxidative leaching were considered. In the first stage, effects of flotation parameters including collector type, collector dosage, and pH and pulp density were examined.
The reprocessing of tailings can have economic and environmental benefits compared to the processing of primary ore deposits. In this paper we present the characterization of a tailings dam in southern Chile by means of mineralogical and geochemical investigations, focusing on sphalerite and trace elements with the aim to investigate a potential reprocessing.
The ancient flotation tailings from Lefke, Cyprus, have a potential for nonferrous metals such as cobalt and copper from more than million tons of reserves containing % Cu, % Co, and % Fe. Recovery of cobalt and copper from these tailings can provide great benefits from economic and environmental perspectives.
There is scope to optimise the froth stability of tailings flotation for enhanced metallurgical performance. Type: Proceedings paper. Title: Optimising froth stability of copper flotation tailings. Event: IMPC 2018 29th International Mineral Processing Congress. ISBN13: .
15/06/2017 · Copper recovery improved as the ore grind became finer. At a 95pct minus 325mesh grind, only 2 pct of the copper was lost in the tailings, indiing a copper recovery of 98 pct. Cyclic Copper Nickel Flotation Tests. To further clarify the flotation response of the shaft sample, several cyclic tests were carried out.
16/11/2020 · Many copper tailings have more SiO2 and CaCO3, some FeS2 and another sulfide. 02 tailings reprocessing method (1)Vulcanization flotation of copper tailings. The essence of vulcanization flotation is to sulfide the ground copper oxide pulp with sulfide and flotation .
· Generally, flotation tailings are produced as a byproduct of flotation and still consist of un‒recovered copper. In addition, it is expected that more tailings will be produced in the coming years due to the increased exploration of low‒grade copper ores.
· Abstract This research aimed at recovering metals retained in the tailings from the flotation of copper (Cu) and cobalt (Co) ores conducted at the New Concentrator in Kipushi (NCK). Metals retention in the tailings (% Cu and % Co) increased due to the removal of the gravity separation section from the processing circuit together with changes arising in the feed mineralogical ...
COPPER EXTRACTION FROM COPPER SMELTER . found that a great effect on copper leaching has the pyrite/flotation tailings: ratio. The best results were The best results were achieved by sulphating of g slag with g of pyrite or g of tailings.
· As ore grades constantly decline, more copper tailings, which still contain a considerable amount of unrecovered copper, are expected to be produced as a byproduct of froth flotation. This research reveals the occurrence mechanism of copper minerals in typical copper sulfide tailings using quantitative mineral liberation analysis (MLA) integrated with scanning electron microscopy–energy ...
There are mainly several methods of gold tailings reprocessing: 1. The iron recovery from gold tailings can adopts common processing technology such as gravity separation, magnetic separation, flotation, roasting magnetic separation and their combined processing technology.
In this paper, the ferric leaching of slag flotation tailings is studied. Copper extractions of 66% are achieved by ferric leaching, and Cu content in tailings is reduced from % to %.
Tailings that are generated in the copper concentrate production contain great amount of sulfide mineral, in particular pyrite. Pyrite in contact with water and oxygen might oxidize spontaneously ...
In the present work six flotation tailings impoundments at five flotation plants (Piuquenes, Cauquenes, El Salvador, Ojancos, P. Cerda) loed in different climatic zones of Chile were selected to investigate the mineralogical and geochemical changes taking place in copper flotation tailings subsequent to sulfide oxidation, especially the formation of acid mine drainage and element mobility.
