As part of the 2002 copper concentrator upgrade, a dedicated, slag cleaning, Jameson Cell, model E2532/6 was installed for cleaning of both converter and RHF slags ( Figure 15) (Carr et al 2003).Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests. This article focuses on industrial flotation, which consisted of two oneyear campaigns (2016 Copper Recovery Through Smelter Slag Flotation in Atacama,

Copper Recovery Through Smelter Slag Flotation in Atacama
Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests.Copper extraction is distinctly profitable when the selling price of copper is above $6/kg. It is unprofitable for some operations when the selling price falls below $3/kg. At the former price, the industry tends to expand. At the latter, it begins to contract. The selling price of copper in mid-2011 was ∼$9/kg.Extractive Metallurgy of Copper ScienceDirect

Pressure Leaching of Copper Slag Flotation Tailings in
In this study, a hydrometallurgical method for the recovery of copper, cobalt, and zinc from copper slag flotation tailings (SFT) was investigated. SFT contains large amounts of valuable metallic compounds, such as copper, cobalt, and zinc. A representative SFT sample containing 0.50% Cu, 0.148% Co, 3.93% Zn, and 39.50% Fe was used in History Miners at the Tamarack mine in Copper Country, in 1905. The Old Copper Complex in North America has been radiometrically dated to 9500 BP—i.e., about 7480 BCE—making it one of the oldest known examples of copper extraction in the world. The earliest evidence of the cold-hammering of native copper comes from the excavation at Çayönü Copper extraction

Extraction and separation of copper and iron from copper smelting slag
The technology of slow cooling and then water cooling has also been adopted by some researchers for enhancing the cooling effect. The slag concentrator of Hitachi Mining Institute is a typical example of CSS beneficiation production practice. The CSS processed by the concentrator contains 6.96% copper and 42.42% iron.Our Aktogay project commenced production of copper cathode from oxide ore via SX/EW in December 2015 and the main sulphide concentrator at Aktogay commenced commissioning in December 2016.

Plant-wide optimization of a copper smelter: how to do it in
The matte grade affects slag blowing times and the copper-in-slag content in the PSC. Feed rate affects the overall schedule and overall production rate. The circulated slag from AF or from copper blow shortens the required slag blowing times and in-creases copper content in PSC slag but has a cooling effect as well. The actual bottleneck of theWith the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content. This trend has had a detrimental Processing of Complex Materials in the Copper

The solid copper concentrate is then sent to the smelter. Smelting. High temperatures further purify the ore in a series of smelting steps. The copper concentrate is first placed in the smelting furnace to be heated up to 1260 °C and converted into molten liquid. The heated liquid is poured into a slag-settling furnace.The Mount Isa Mines (MIM) copper concentrator at Mount Isa processes both chalcopyrite ore from the MIM underground mine and rotary holding furnace (RHF) slag from the MIM copper smelter.
