recovery of copper from reverberatory furnace slag by flotation

Recovery of Copper from Reverberatory Copper Slag and, flotation to recover entrained copper contents This technique produces a flotation concentrate copper, Fe removal from the leaching of copper slag is done by the formation of a metal hydroxide Hydrolysis 2004/3/1The recovery of copper from reverberatory furnace slag utilizing flotation has been studied. The effective factors such as particle size, pH, the amount and type of collector and additives, and flotation time were examined. The effect of cooling rate on flotation behavior

Characterization and recovery of copper values from discarded

of copper are mostly present within the slag phase and to some extent the slag is also embedded inside the oxide and sulfide phases. The recovery of copper values from the discarded slag has been explored by applying a flotation technique using con-

Recovery of Copper from Reverberatory Copper Slag and, flotation to recover entrained copper contents This technique produces a flotation concentrate copper, Fe removal from the leaching of copper slag is done by the formation of a metal hydroxide Hydrolysis

This slag contains large amounts of metallic values such as copper and cobalt. A representative slag sample containing 0.98% Cu, 0.49% Co and 51.47% Fe was used in the experimental studies. Two different methods, direct acid leaching and acid baking followed by hot water leaching were used for recovering Cu and Co from the slag.

Enhancing The Flotation Recovery Of Copper Minerals In Submerged lance, copper converter and reverberatory furnaces, in order to produce mattes and fayalitic slags.The copper content of the slags range between 0.8 to 5 wt.And this is considered too high for

iron recovery from slag processing

Laboratory and pilot plant investigations have indicated that copper recoveries of 50% can be achieved with fine grinding and flotation of a copper reverberatory furnace slag. Microscopic and microprobe studies indicate that the recoverable copper is in the form of matte, chalcocite, and metallic copper; the percentage of copper in particles appearing to be copper-free was from 0.23 – 0.54%

Application to Co recovery by slag cleaning Mineralogical studies have shown that cobalt is present as CoO in copper reverberatory furnace slag. Copper in the slag is mainly attributed to the presence of copper-rich sulphides. The cobalt oxide, and, to a lesser

Cobalt-Recovery from Copper-Smelter-Slags6 In January 2001, Chambishi Metals commissioned a 40 MW DC arc furnace using selective carbothermic reduction for processing reverberatory furnace slag stockpile of 20 million tons containing 0.34 to 4.5%

Copper Cobalt Africa, incorporating the 8th Southern African Base Metals Conference Livingstone, Zambia, 6–8 July 2015 Southern African Institute of Mining and Metallurgy 247 Recovery of Copper from Reverberatory Copper Slag and Production of a Leach

Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were 63.4% and 48.6%, respectively, when leaching the slag with 3 M H2O2, after 120 minutes of reaction at room temperature.

Recovery of Copper and Silver by Flotation from Smelting The recovery of copper from smeltery furnace slag by flotation has been studied. By analysis the slag containing 1.61% copper and 27.80g/t silver is available to recovery. The effective factors such as

Factors influencing base metal recovery from waste

The recovery of cobalt and copper from waste slag was studied in a plasma DC-arc furnace in reducing conditions. Three fluxes, CaO, CaF 2, and TiO, were investigated for their influence on selective recovery of cobalt into an iron-rich alloy. A further investigation

Recovery of Copper and Silver by Flotation from Smelting The recovery of copper from smeltery furnace slag by flotation has been studied. By analysis the slag containing 1.61% copper and 27.80g/t silver is available to recovery. The effective factors such as

Pdf Recovery Of Copper And Cobalt From Converter Slag Recovery of copper from reverberatory furnace slag by flotation copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions without or. Online Chat

Copper recovery is generally achieved by pyrometallurgical routes. For ex- ample, re-cycling converter slags with high copper content to the reverbera- tory furnace, or using a separate slag refining furnace. However, in this pro- cess some

Recover Copper From Reverberatory Furnace Slag Laboratory and pilot plant investigations have indicated that copper recoveries of 50 can be achieved with fine grinding and flotation of a copper reverberatory furnace slag microscopic and microprobe studies indicate

In this work extraction of copper and iron from a reverberatory furnace slag was studied. A two-step extraction procedure was followed. The first step was roasting of the slag in the presence of sulphuric acid at temperatures between 150 and 800 oC.
