World’s largest flotation cells improve copper and molybdenum recovery in Mexico The first two Outotec TankCell ® e630’s – the largest operating flotation cells in the world at 630 m 3 – are running at the Buenavista del Cobre (BVC) concentrator in Northern Mexico.
copper. Batch flotation tests were used to assess the performance in terms of mass-water recovery, sulphur grade-recovery and copper grade-recovery relationships and the Klimpel rate constant for copper recovery. The results showed that the di-ethyl-dithiocar-bamate (di C2-DTC) was the weakest collector of copper sulphide minerals.
Improving Flotation of Sphalerite - Effect of pH and Activating Potential on the Kinetics of Copper Uptake and Xanthate Adsorption on Sphalerite 6.1. Abstract The effect of pH and electrochemical potential on copper uptake, xanthate adsorption and the hydrophobicity of sphalerite were studied from flotation practice point of view using
RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching.
I have been given a project on optimization of copper concentrate grade so as to improve copper and gold recovery. I need help on the main factors which I have to consider in my project. The targeted copper concentrate grade at the plant is 18- 20%Cu, but currently the target is not achieved. ... Froth Flotation (Sulphide & Oxide)
pyrite associations are problematic in porphyry copper-gold flotation due to the requirement to minimise sulphur content (improve concentrate grade) in the final Cu concentrate. For example, in most Cu-Au flotation plants (i.e. Telfer gold mine, OK Tedi, Freeport Indonesia, etc.), in order to increase Cu and
Improving copper flotation recovery from a refractory copper porphyry ore by using ethoxycarbonyl thiourea as a collector. ... and the energy of normal covalent bond between PECTU and iron sulfide mineral was low enough for improving its selectivity against iron sulfide mineral.
Improve coarse particle flotation using Eriez Hydrofloat Posted by John on 11th October 2017 The copper sulphide processing flowsheet has remained virtually untouched for decades and follows a logical progression – crush, grind, float, regrind and refloat to produce a final copper concentrate.

Introduction to Mineral Processing. ... They are used to improve the selectivity of a flotation process. They often make it feasible to separate minerals that were initially floated together. ... and ore body variation are just a few of the variables affecting the flotation process. Copper/Molybdenum Ore.
Magnetic conditioning of flotation feed has been shown to improve the flotation of <38 μm paramagnetic minerals consistent with selectively aggregating these paramagnetic minerals. The process was evaluated using shift composite samples that were analysed for copper and gold.
Benchmarking performance of StackCell with conventional cells for bulk copper flotation roughing . StackCell Brochure. Testing and Technical Services Brochure. CrossFlow Brochure. ... By classifying flotation feed at a point where coarse recovery deteriorates, the existing flotation circuit can be optimized to improve performance.
Copper sulphate is widely used in base metal sulphide flotation circuits to improve the process efficiency. As with Xanthates, the reactions involved are dependant on the ore type and the characteristics of the multiphase flotation system. One mechanism described is the electrochemical reaction where the metal ion on the
