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.

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 .
The analysis of highly reduced slags has shown that it is possible to remove virtually all of the cobalt and nickel from the olivine in the slag. Nickelcopper converter slag ''B'' MVA. Largescale testwork on converter slag was conducted, during 1994, on a MVA DCarc furnace operating at a .
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.
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
Highlights Cu is efficiently leached from copperzinc waste by H 2 SO 4 solutions with Fe 3+ ions. Fe 3+ ions inhibit zinc and iron leaching from converter slag flotation tailings. Copper and zinc leaching is controlled by chemical reaction on the particle surface.
copper flotation from converter slags YouTube. Aug 25, 2016 This is a simple video slideshow, if you want to know more details, please click on our website, we will provide a p. Leaching of copper and zinc from copper converter slag flotation .
Laboratory batch flotation tests were conducted on copper converter slags to evaluate the relative merits of recovering copper from slow cooled versus waterquenched slags. Three slags containing,, and percent copper were used. More than 90 percent of the copper was recovered in a ...
Abstract. Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copperbearing mineral after a detailed mineralogy analysis via .
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 .
Primary Copper Smelting General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the megagrams (Mg)
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 copperfree was from – % ...
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 highgrade matte which runs at 74% or 92% nickel plus copper (and 20% and 6% sulphur contents) according to customer specification2. Presently around 120 tonnes
In the November issue of Teniente Topics, the monthly publication of the Braden Copper Co., Chile, a member of the staff briefly outlines the development of the smelter from 1909 to the present time. Metallurgical difficulties have been many, but were overcome, in spite of being 6000 miles from the base of supplies. The plant now treats 350 tons of concentrate daily, yielding 60 tons of copper ...
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.

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 nowuncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.
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 copper 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%.
About 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 % Cu, % Co and % Fe was used in the experimental studies.
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
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 ...
Copper extraction refers to the methods used to obtain copper from its 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.
