  • Filtration of Copper/Gold Tailings for Mine

    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 application the filtered tailings need to have a certain residual moisture to ensure constant conditions for

  • Copper extraction - Wikipedia

    Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.

  • Response Surface Methodology for Optimization of Copper

    flotation copper tailings. The proportion of the refractory combination oxide copper (chrysocolla) is 64.84%. At present, few studies have examined the leaching of chrysocolla. In this study, we examine the effects of several variables, including the amount of concentrated sulfuric acid, leaching temperature, and leaching time, on leaching efficiency. Using a response surface methodology, we

  • Recovery of pyrite from copper tailings by

    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

  • Development of copper recovery process from

    15.06.2018· 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. Therefore, this research aims to develop a copper recovery process from flotation tailings using high‒pressure leaching (HPL) followed
