This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from 100%: % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of

The copper mine preferential flotation method, that is, the three-stage open-circuit crushing and one-stage grinding process, preferentially float copper to obtain copper concentrate and sulfur concentrate, and then Magnetic separation gives iron concentrates, and finally two stages of dehydration are carried out from copper and sulfur

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4

Sep 29, 2016 Patented process in use at Saudi Arabia mine and in Chile Flotation froth of copper concentrate during laboratory testing in Santiago, Chile Barrick has developed and patented a new flotation process that can produce copper concentrates from copper or copper-gold ores using salt or brackish water. The new process, an air-metabisulfite treatment, does not require lime or cyanide

the amount of water required to process copper sulfide ore through a conventional crush-grind-flotation- concentrate circuit ranges from roughly 1.5 metric tons (t) to about 3.5 t

grind size of the ore can have on copper concentrate production during flotation process. Therefore this research was more focused on determining whether the size distribution of the ore after comminution would cause significant impact on copper ore response in the floatation process. Comminution

His Bradford washer, patented 1870, was used to concentrate iron, copper and lead-zinc ores by specific gravity, but lost some of the metal as float off the concentration process. The 1886 patent was to capture this float using surface tension, the first of the skin-flotation process patents that was eclipsed by oil froth flotation

Oct 01, 2012 There are several flow sheets (listed in Fig. 1a and b) used in the flotation recovery of copper and molybdenum from their porphyry sulfide ores. Fig. 1a is a typical flow sheet that consists of two stages (Raghavan and Hsu, 1984, Bulatovic, 2007, Liu et al., 2011).The first stage, commonly known as the copper circuit, produces a bulk copper sulfide–molybdenum sulfide concentrate

in mill feed. Their impact on final concentrate fluorine levels is entirely dependent on the flotation process response of each of these minerals, and is in essence the subject of this paper. The fluorine content of Ok Tedi copper concentrates varies typically from 250 • 900 ppm in concentrates that are sent to various smelter customers

Xinhai Solutions: Xinhai Mine Research Institute carried on preliminary exploration of its processing conditions and found that the copper recovery rate was the highest in bulk flotation process. Therefore, after discussed with client, Xinhai adopted two stage closed-circuit crushing, one stage closed-circuit grinding, middlings regrinding, copper lead bulk flotation - zinc flotation - copper

Subsequent cleaner flotation with additional ozone conditioning results in relatively copper-free molybdenum concentrates containing as much as 52% Mo. Preliminary analysis indicates that, with a multistage ozone conditioning/flotation strategy, the process is technically and economically viable and should be suitable for industrial application

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different
