COMPARATIVE RESULTS OF COPPER FLOTATION FROM

Production of copper concentrate by flotation of smelter slag has started in 2001. Flotation concentrate goes to the Copepr Smelter once more for production of cop-per cathodes and the rough flotation tailings go to the flotation tailing dump. Copper recoveries in the flotation process of smelter slag reaches the value of about 45- 50%.

Biorecovery of copper from converter slags: Slags

Jun 01, 2009· The concentration of Cu in slag from smelting is typically in the range 0.5 to 2%, while converter slags can contain 2 to 15% Cu. This is a considerable amount of copper very much higher than those of many ores. The high content in copper requires a treatment for Cu recovery.

Enhancing the flotation recovery of copper minerals in

Jan 01, 2020· The slags produced from the NCS furnaces (TSL furnace, copper converter, reverberatory furnace) contain copper ranging between 0.8 to 5% w/w. Due to this high content of copper, the slags are milled and floated to recover the copper. The main drawback in the current process is that the final flotation tailings grades are in excess of 0.9% Cu.

Minimizing of copper losses to converter slag by a boron

Nov 01, 2019· Considering the initial copper content (4.45% Cu) in converter slag, it can be deduced from the Fig. 6 that the loss of copper to the slag is decreased to very low levels (2.5% Cu) independently of CC addition. It is concluded that the copper losses can be significantly reduced by keeping the converter slag in the settling furnace.

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
