Mar 01, 2004· The 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 of the slag .
TiJmen, F. and Bailey, N.T., 1990. Recovery of metal values from copper smelter slags by roasting with pyrite. Hydrometallurgy, 25:317-328. Sulphation roasting of primary and secondary copper slags has been carried out to facilitate the dissolution of copper, nickel, cobalt, zinc and iron.
This study was designed to recover copper and cobalt hydrometallurgically from an enriched concentrate of flotation and converter slag. Three slag samples collected from the Ergani Copper Co. of Etibank were studied. In order to convert the copper and cobalt into sulfate compounds, samples were roasted after sulfurization and leached with water.
The 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 of the slag was also studied.
In the first flotation stage, as much copper as possible is recovered in a rougher concentrate so that as little as possible goes to the tailings. To increase the copper recovery ... intermediate products (e.g., cement copper or copper(I) oxide precipitates), reverts (e.g., converter slag, refining slag, or flue dusts), and copper-alloy scrap.
copper slag recovery through a flotation route. Almost in all of the flotation methods used to recover copper from slags, the Cu recovery was associated with many problems such as high grade of copper in tailing. In the present study, the use of grinding time increased the copper slag recovery a lot.
MANAGEMENT OF COPPER PYROMETALLURGICAL SLAGS 543 Introduction During the last years, due to world-wide economic recession and a large inventory of stock, copper reached a historical value of 0.59 US$/pound in 2001. This fact meant closing down many important mining companies in the world, mainly in USA. On the other hand, strong
Aug 26, 2016· Portable Crushing Plant; Grinding Mill. copper flotation process in malaysia manufacturer in Shanghai Flotation Reagents Copper Slag copper flotation from converter slags . copper flotation from ...
Recovery of metal values from copper slags by flotation and roasting with pyrite. ... Roasting of copper converter slag containing 4.03% copper, 1.98% nickel and 0.48% cobalt with ammonium ...
Laboratory batch flotation tests were conducted on copper converter slags to evaluate the relative merits of recovering copper from slow- cooled versus water-quenched slags. Three slags containing 1.6, 5.0, and 6.6 percent copper were used. More than 90 percent of the copper was recovered in a ...
Recovery of cobalt from converter slag of Chambishi Copper ... techniques, such as slag cleaning, slow cooling of the slag followed by milling and flotation, are inappropriate for cobalt recovery from converter slag [7−8].
Recovery of Copper and Cobalt from Copper Slags as Selective 389 intervals. By treatment with hot water, recovery of copper and cobalt from the ore mixture was aimed selectively. 2. Experiment 2.1 Sample Preparation The slag sample used in this investigation is a composite from different levels of the copper slag
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.

Recently smelter copper slags stockpiled in dumps are being reprocessed by crushing, milling and flotation to recover entrained copper contents. This technique produces a flotation concentrate copper grade of approximately 25 to 30% with copper recoveries of between 60 and 70%. However, the
Optimization of the flotation of copper smelter slags from Namibia Custom Smelters' Slag Mill Plant Elias Sipunga A research report submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, in partial fulfillment of the requirements for the degree of Master of Science in Engineering
About 2.5 million tonnes of copper smelter slag are available in Küre, northern part of Turkey. 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.
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% ...
Mihajlović - The effect of cooling rate of slag from primary copper production . 129 In Table 1 an overview is given of copper content in flotation tailings in smelters which process slag by flotation. Table 1. Copper content in flotation tailings in different smelters Smelter %Cu Almalykskii, Russia 0,27 Garfield, USA 0,48 Guixi, China 0,50
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.

Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. A now-uncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.
to induce the grain growth of copper matte and magnetite by modifying the molten copper slag. As a result, it is effective to improve recovery and separation of copper and iron from the copper slag; meanwhile, the latent heat energy of the molten slag was effectively utilized and .
converters is further treated in the Converter Slag Cleaning Vessel for further cobalt recovery. The final product from the converters, usually refined in Norway, contains high-grade matte which runs at 74% or 92% nickel plus copper (and 20% and 6% sulphur contents) according to customer specification2. Presently around 120 tonnes
