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- 20Cu, but currently the target is not achieved. The p
After first flotation on 10kg of copper ore sample with a feed grade of 2.3 percent copper, we have a concentrate with copper grade of 9 percent, recovery of 97 percent. The grade is too low to benefit, then we float again with a concentrate mass of 477.3 grams and a stage copper recovery of 92 percent.
Jan 01, 2020 The recovery was calculated using the following formula 1 R e c o v e r y M c o n c e n t r a t e C u c o n c e n t r a t e M c o n c e n t r a t e C u c o n c e n t r a t e M t a i l i n g s C u t a i l i n g s where M concetrate is the weight mass of the concentrate in grams after flotation, Cu concentrate is the copper ...
The ways to obtain successful Separation of Copper and Lead into individual Concentrates, several process approaches can be examined bulk copper-lead flotation with a reverse flotation stage depressing copper, the same bulk flotation with a reverse flotation to depress lead and a sequential copper-lead-zinc flotation circuit as well as a simple cleaning of the bulk CuPb concentrate
concentrates of lean and typical copper ores. Effect of column parameters viz. air flow rate, feed flow rate and column height were studied in addition to usual flotation parameters.
Jan 01, 2003 The bioleaching of flotation concentrate is a new method for copper recovery that could form the basis of an economic and environmentally friendly process. The main objective of this work was to evaluate a bioleaching process from the treatment of two concentrates, i a copper gold bearing concentrate and ii an ordinary copper flotation ...

complex mixture of copper sulphide and small amount of copper oxide minerals. However, a number of flotation parameters have not been optimized to meet concentrate standards and grind size is one of the parameter. The purpose of this
In some cases the copper concentrate may contain up to 10 15 As after flotation. The case is different if arsenic is present as arsenopyrite, FeAsS in the ore. The presence of arsenopyrite in a copper concentrate can be avoided by selective flotation of copper mineral and not of

For copper sulfide ore, when it uses xanthate as a collector, it has the best floatability, but usually a lot of inhibitors are needed to suppress it. 2.Copper-molybdenum mixed concentrate separation process . For the flotation separation of copper-molybdenum mixed concentrate, it can usually be divided into 3 steps. Pretreatment.
characteristics, Hellyers sequential flotation circuit versus Cadias simple coppergold flotation circuit. They have a common theme in that pyrite forms the principal floatable concentrate diluent. Hellyer ore contains finely disseminated chalcopyrite, sphalerite, galena, and tetrahedrite.
Copper present in the flotation concentrate was observed to be solubilised in the leaching solution only after the conversion of all copper sulphide minerals into the covellite phase.

Pine oils, cresylic acid, and long-chain alcohols are used for the flotation of copper ores. The flotation concentrates are then dewatered by clarification and filtration, resulting in 10 to 15 percent water, 25 percent sulfur, 25 percent iron, and varying quantities of arsenic, antimony, bismuth, cadmium,
Flotation of sulphide nes results, using CRF technique and HIC combined CRFHIC, were compared with a standardized mill laboratory procedure. Concentrate copper recoveries were of the order of 7 18 per cent higher and their process kinetics values were higher, 1.5 min 1for CRF and 2.9 min for
Copper Sulfide Flotation Circuit Beneficiation of Copper Sulfide by Flotation Copper, due to the present world demand and price, is of foremost interest to the mining industry. Many new properties are either in the process of being brought into production or are
The copper flotation circuits upgrade copper content by a factor of 80-160 times from feed to a saleable copper concentrate containing approximately 50 of the contained gold in feed remaining gold is recovered both as a gravity product
