This study presents the results of the sizing of a thickener that treats copper concentrate ore slurry from the flotation process.
8.1.1 From the Stone Age to the Middle Ages. Thickening is not a modern technique and was certainly not invented in the Americas. Whenever people have tried to obtain concentrates from ore, two processes have been used inseparably, crushing and washing.There is evidence that in the 4th Egyptian dynasty, around 2,500 BC, the ancient Egyptians dug for …

By example a typical copper concentrate may have a TML of 9% moisture. Given that at the incompressible limit the cake will have a solids fraction of about 50% v/v and for solids with an sg of 4.3 ...
The pyrometallurgical copper refining process In pyrometallurgy, intense heat, often at 2,300 degrees Fahrenheit, is applied to extract copper from sulfide ores.After the flotation process ...
The invention discloses a method for separating copper-molybdenum mixed concentrate high in secondary copper content. The method includes the steps of concentrating and filtering, water returning and size mixing, floatation separation, concentrate filtering and the like. The method abides by floatability property difference between copper molybdenum minerals, adopts …
A high-rate thickener dewaters the bulk of copper-moly concentrate before more separation. 5. Moly Flotation. The moly flotation circuit has similar groups of flotation cells with chemicals to float the molybdenite (moly concentrate), and settle out the copper sulfides (copper concentrate). 6. Copper Thickening/Dewatering
2) Copper concentrate filtration is the operation of making the ore slurry pass through a water-permeable and impermeable spacer layer of solid particles to achieve solid-liquid separation. Filtration is a further dehydration operation after concentration, usually on a filter. 3) Copper concentrate drying is the final stage of dehydration. It ...
After crushing and milling steps the slurry of copper go to the flotation process in order to separate the copper concentrate from the copper tailings. The last step of the process before the copper concentrate filtration is the thickening of the copper concentrate slurry by the high rate thickener.
for: rougher concentrate regrinding testing, copper concentrate, thickening and filtrationrheology testing, and final tailings rheology and thickening testing. No further confirmatory testwork was undertaken during the feasibility study optimisation review or FEED phase. Table 2.
Sumitomo Metal Mining Co. Ltd. (headquarters: Tokyo, Japan, "SMM") and Sumitomo Corporation (headquarters: Tokyo, Japan, "SC"), together with Teck Resources Limited (headquarters: Vancouver B.C., Canada, "Teck"), have started the feeding of mineral ore into the main facilities at the Quebrada Blanca Phase 2 project ("QB2 Project"), and the production of …
In the thickening and decantation area, the bulk concentrate, which has undergone atmospheric leaching, will undergo the thickening procedure in special tanks. Thickening is a process of separating solid and liquid fractions based on the natural settling of solid particles under the influence of gravity and reagents.

This paper presents residence time distribution (RTD) functions acquired in radioisotope tracer experiments carried out on a copper ore thickening, filtration and drying system. The radioactive isotope 64 Cu was selected as a tracer for copper. It was obtained through the activation of the natural ore concentrate in a nuclear reactor.
Copper Flotation is a beneficiation method based on the hydrophobicity difference of the mineral surface. While the copper mineral is usually in the form of sulfuration exiting in the mineral. ...

The AAC/UBC process was recently evaluated in a continuous, fully integrated pilot-plant trial. The flow sheet comprised fine grinding of the concentrate, pressure leaching, thickening and filtration, copper SX/EW, with a bleed circuit to recover valuable base metal co-products. Gold was recovered from the autoclave residue by direct cyanidation.
