Friedberg et. al. 2014. However, our interest is not limited to arsenic but extends to other impurities found in copper and nickel concentrates as well. One considers a typical copper concentrate as having about 25+ copper and some minor quantity of impurities, preferably rich in precious metals.
Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20 and 30 copperinconcentrate usually 2729 copper the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena.
Zinc smelting is the process of converting zinc concentrates ores that contain zinc into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific
senic, zinc and aluminum et al. 17. The copper concentrate is oftenobtained by conventional flotation process, but those impurities of molybdenum, arsenic, zinc and aluminum usually exist in copper concentrates. Molybdenum, aluminum and zinc are valuable metals worthy of being recovered, but arsenic lowers
Impurities such as copper, antimony, zinc and aluminum have an effect on soldering quality and should be kept to a minimum. The amount of impurities in the solder was related to observed defects or solder conditions. impurities may be acceptable atpany and cause for rejection atpany.
Copper/zincmercial terms for these materials are constructed and calculated in the same way as copper concentrate but levels of Payment , TC and RC are not necessary following the copper concentrate terms. Legislations and green image are strong drivers to recycle material suitable for a copper smelter.

Jun , if the content of pyrite sulfur in the tails is more than , these tails are pyrite concentrate the coarse copperzinc concentrate containing copper and zinc after regrinding to a particle size of class minus microns is peeled three times in a lime medium, where ph up to for depression of pyrite
