Utilization of high-gradient magnetic
2019-6-1 Copper-oxide raw ore has a complex composition and cannot be processed effectively by conventional, single-stage sorting methods. Based on the characteristics of copper-oxide ore, a new combined grinding–flotation–high-gradient magnetic separation–secondary grinding–leaching process has been proposed to recover copper.
Copper Recovery from Yulong Complex Copper Oxide Ore
2017-5-25 A combined process of flotation and high-gradient magnetic separation was proposed to utilize Yulong complex copper oxide ore. The effects of particle size, activators, Na 2 S dosage, LA (a mixture of ammonium sulfate and ethylenediamine) dosage, activating time, collectors, COC (a combination collector of modified hydroxyl oxime acid and xanthate) dosage, and magnetic intensity

A New Technique for Recovering Copper From Complex
2018-9-24 Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotation–high-gradient magnetic separation–leaching is proposed here to recover copper minerals. The test results showed that the flotation process was successful when using sodium sulfide as a vulcanizing agent and butyl xanthate

Copper oxide supported on magnetic nanoparticles
2017-1-16 Copper oxide supported on magnetic nanoparticles was used as a green magnetic nanocatalyst for hydroamination of carbodiimides towards the synthesis of guanidines. Easy preparation and separation, low cost, non‐sensitivity to moisture and reusability of the catalyst along with diversity and high yield of products are significant features of
Methods for Separation of Copper Oxide Nanoparticles
2014-4-4 Mixing copper oxide (CuO) nanoparticles in the paraffin produces an effective and highly efficient NEPCM for energy storage. However, after long term application cycles, the efficiency of the NEPCM may deteriorate and it may need replacement with fresh supply. Disposal of the used NEPCM containing the nanoparticles is a matter of concern.
