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
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 ...
TiJmen, F. and Bailey,, 1990. Recovery of metal values from copper smelter slags by roasting with pyrite. Hydrometallurgy, 25:317328. Sulphation roasting of primary and secondary copper slags has been carried out to facilitate the dissolution of copper, nickel, cobalt, zinc and iron.
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.
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 Sample Preparation The slag sample used in this investigation is a composite from different levels of the copper slag
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...
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.
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 .

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.
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
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%.
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 ...
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
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 .
A flotation process in which copper ores or copper converter slags are ground and firstly have added thereto benzotriazole or alkyl benzotriazole as an activator and secondly one or more collectors selected from the group consisting of xanthates, dithiophosphates, thiocarbamate esters, dithiocarbamates, mercaptans and dixanthogens and further, if desired, a promoter such as kerosene, light oil ...
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 ...
MANAGEMENT OF COPPER PYROMETALLURGICAL SLAGS 543 Introduction During the last years, due to worldwide economic recession and a large inventory of stock, copper reached a historical value of US/pound in 2001. This fact meant closing down many important mining companies in the world, mainly in USA. On the other hand, strong
Recovery of metal values from copper slags by flotation and roasting with pyrite. ... Roasting of copper converter slag containing % copper, % nickel and % cobalt with ammonium ...
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 – % ...
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.
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.
