It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and : Jiaqi Fan, Hongxu Li, Liangtian Wei, Chao Li, Shi Sun. The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue.

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. All these three furnaces produce fayalite slag as a byproduct. The slags contain copper with the content ranging between to 5% copper. The slags cannot be discarded due to the high content of copper and hence they are sent to a milling and flotation plant (Slag Mill Plant) for liberation and recovery 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 by: following three methods are generally utilized for recovering the copper from these slags on an industrial scale: (i) recycling of the converter slag to the smelting furnace, (ii) cleaning of smelting and/or converter slags in electric furnaces and (iii) flotation.

Metallic copper and sulphide copper present in these slags can be floated very. Converter Slag Copper Loss Copper Recovery Magnetite Content Flotation Concentrate These keywords were added by machine and not by the authors.

This process is experimental and the keywords may be updated as the learning algorithm improves. 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. Key words: Copper, cobalt, slag, roasting, pyrite, copper concentrate. Introduction Significant amounts of copper, cobalt and nickel can be obtained from copper slags, which are produced in the thousands of tons per year in copper smelters.

Very different methods were used to recover metals from the copper converter slags. 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.

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, and percent copper were used. approximately 12 million tons of copper slag is produced every year, and the amount of accumulated waster copper slag reached million ton by in China [6]. Generally, copper slag contains about 35–45 wt.

% iron and – wt. % copper, indicating that it is a valuable secondary resource for recycling and utilization [3].

Ausmelt furnace slag contains about % Cu (mass %). With increasing the amount of Ausmelt furnace slag, the recovery of copper from it will produce an enormous economic yield.

The recovery of copper by floatation from slow cooled Ausmelt furnace slag was studied in this paper. The phases and composition of the slow cooled slag were analyzed.

Flotation process and choosing appropriate reagents recovery of copper is approximately 75 along with copper content in basic copper concentrate of 42 leaching analysing the tailing of copper flotation from smelter slag it was noted that there is a significant copper content in it copper. Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper.

The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue.

Recovery of copper from converter slags by flotation / By Vernal E. Edlund, S. Hussey, Salt Lake City Metallurgy Research Center (U.S.). and United States. Bureau of Mines. A modal examination of the products produced by the copper flotation rougher-scavenger circuit reveal important information regarding the limits to the efficiency of the process, imposed by mineralogy, fragmentation and flotation capacity.

Let’s discusses various aspects of rougher flotation circuit performance and how to evaluate its results. materials from copper slag. Recovery of copper, molybdenum, precious metals, silica and iron, that is the most abundant component of the slag, are the goals for this research.

Metals, commercial compounds, alloys and different forms of iron oxides for steel industry are proposed products. 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.

Nickel-copper converter slag 'B' - MVA. Large-scale testwork on converter slag was conducted, duringon a MVA DC-arc furnace operating at a. Ancient gold smelting rare today.

In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated. The recovery of copper from smeltery furnace slag by flotation has been studied.

By analysis the slag containing % copper and g/t silver is available to recovery. The effective factors such as particle size, the amount and type of collector were examined.

The combination of. Copper is present in a smelting slag from Teniente Converter (TC) in the form of mecha-nically entrained matte inclusions and dissolved copper. Copper recovery from the slag requires magnetite reduction to liberate matte inclusions and create conditions for co-reduction of dissolved cuprous oxide.

time, collector type and addition on efficiency of tennantite flotation. It was shown that maximum copper recovery of 95,3% was obtained at pH by was suggested to grind up to % of mm to achieve the optimum recovery of copper and high grade of arsenic in concentrate.

Under optimum flotation conditions, it is possible to achieve 21% Cu with more than 80% recovery. Keywords: copper slag, ore mineralogy, Raman spectroscopy, scanning electron microscopy, X-ray diffraction, slag flotation Introduction It has been estimated that for each ton of copper produced about tons of slag are generated.

These slags contain. The recovery of copper values from an Indian smelter slag that contains % Cu, % Fe and % SiO 2 was the focus of the present study.

A complete investigation of the different phases present in the slag has been carried out by means of optical microscopy, Raman spectroscopy, scanning electron microscopy (SEM), and X-ray diffraction.

per Works, Turkey, about tons of slag are treated annually by the flotation process, after being crushed and ground, to recover additional copper values (Arslan & Ars-lan ). However, it has been estimated that a copper recovery higher than 80% is required to make such a .Recovery Of Copper From Reverberatory Copper Slag.

Flotation to recover entrained copper contents this technique produces a flotation concentrate copper copper slag is 2a form of olivine a magnesium iron and silicate mineral with the formula mg fe2 2 sio 4 the production of nano silica from the dissolution of olivine is an economic option when.copper converter slag, such as re-smelting or flotation, are effective for recovering the copper only (Biswas & Daven-port ).

The cobalt in converter slag, however, remains in re-smelting slag or flotation tailings, and eventually gets lost with their disposal. The recovery of cobalt from slag requires a special separation process.
