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.
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 .
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
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.
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
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

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.
Key words: Converter slag, flotation, copper, cobalt, sulphurization. 1. Introduction Copper slag is produced in large amounts in seven copper smelter plants in Chile, and it is estimated that around 4 million tons of slag are disposed every year and another 40 to 45 million tons are historically cumulated [1].
Feb 08, 2017· 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 polarizing microscope, SEM and XRD.
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

A study on the recovery of copper, cobalt, and zinc from copper smelter and converter slags by roasting with sulfuric acid has been conducted. Acid roasting of slags followed by hot water leaching was carried out to bring the metal values into solution.
In the Outotec PS Converting Process, the molten matte from the smelting furnace is converted into blister copper. Converting is carried out in two stages. The first stage is the slag blow, where iron contained in the matte is slagged and removed before the copper blow phase.

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 (, cement copper or copper(I) oxide precipitates), reverts (, converter slag, refining slag, or flue dusts), and copperalloy scrap.

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.
