The recovery of copper from smeltery furnace slag by flotation has been studied. By analysis the slag containing % copper and /t silver is available to recovery. The effective factors such as particle size, the amount and type of collector were examined. The combination of .
This work presents the study of copper extraction from smelter slag, which is subjected to sulphating. Sulphating of slag was performed by pyrite concentrate or flotation tailings at temperatures from 500 to 650°C, and the resulting calcine was leached with water. The results showed that maximum copper

The recovery of copper from copper smelter slag utilizing flotation has been studied. A copper smelter slag from the Wang Jiaqiao smelter in Yunnan Province of china, containing % Cu, % Fe, % Zn and /t Ag and so on, has been used .The effective factors such as grinding fineness, pH, and the dosage and type of collector were examined.
The flotation reagents can be added in a feedforward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclearbased sensors have been tried with limited success.
Oct 10, 2015· However, among the various processing method, physical separation by froth flotation is widely applied and some researchers considered flotation as an effective method to recover copper from slag. Understanding the slag mineralogy and associations of copper in the flotation feed is crucial to optimise operations.
Copper slag flotation plant xsm excellent mining crushing machinery products or production line design the company is committed to building the chinese brand mine crushing and processing machinery mainly crusher mill sand making our products copper slag flotation plant in more than one hundred of the worldsales of countries and regions .
Abstract: Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Converter slag Reverbetory furnace slag Copper recovery Flotation Milling and grinding ABSTRACT Namibia Custom Smelters (NCS) process a range of copper concentrates in their three furnaces, namely; top submerged lance, copper converter and reverberatory furnaces, in order to produce mattes and fayalitic slags. The
flotation tests which were performed on slag samples from three different sources (TSL furnace, copper converters, reverberatory furnace) to recover the copper minerals. A range of commercial flotation reagents including xanthates, dithiophosphates, mercaptobenzothiazole,
copper slag flotation plantmarinetaxis. Improving Beneficiation of Copper and Iron from Copper Slag by Apr 14, 2016 iron components from copper slag, by modifying the molten slag to promote the mineralization recovery of iron from copper flotation slag, more prior works focused mostly on .. made in continuous pilot plant smelting trials.
The recovery of copper values from the discarded slag has been explored by applying a flotation technique using conventional sodium isopropyl xanthate (SIX) as the collector.
Copper loss in the slag of Khatoonabad flash smelting furnace is estimated to be about 1–3 %. At present, the electric slag cleaning furnace is used for the recovery of copper from slag. However, due...
Copper Ore Slag Copper Flotation Cell We are a largescale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.
flotation of slow cooled copper slag. Ultimately, the process needed to achieve superior recovery of copper at a natural pH over a specific grind fineness. Xstrata''s key requirements were to: • Identify superior collectors • Reduce reagent costs • Optimise flotation performance • Integrate improvements into existing operations
slag flotation tailings are inferior in terms of leaching when compared to the slag because most of the liberated copper phases have been removed by flotation. Based on the chemical compositions of the slag and the slag flotation tailings Table 1, it can be concluded that the copper dissolved from the slag flotation tailings mainly originates
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
because copper slag has a bond work index of 22 kWh/t and is thus a very hard slag. The process also has reduced flotation recoveries and requires high flotation reagent consumption. The present work shows that digestion of the milled copper slag slurry with concentrated sulphuric
Roasting of copper converter slag containing % copper, % nickel and % cobalt with ammonium sulphate open to atmosphere has been carried out in order to achieve sulphation of copper . Inquire Now; Froth flotationWikipedia. Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.
Reagent scheme used for flotation of sulfide copper ores Unlike porphyry copper ore, where the reagent schemes are similar for most operations, the reagent schemes used for the treatment of sulfide copper ores are much more diverse and are designed to cope with specific problems associated with processing the ore.
Various flotation reagents that are commonly used for copper flotation were identified, selected and used during the flotation test work in order to identify the best reagent best suited to float the copper slags. Potassium amyl xanthate (PAX) and Flotanol CO 7 .
slag flotation tailings are inferior in terms of leaching when compared to the slag because most of the liberated copper phases have been removed by flotation. Based on the chemical compositions of the slag and the slag flotation tailings Table 1, it can be concluded that the copper dissolved from the slag flotation tailings mainly originates
