Flotation is an important technology to recover copper from copper slag. There are a few industrial flotation facilities for treatment of copper slag, such as Magma Copper San Manual facility, USA, Altonorte Flotation Plant, Chile, Outokumpu facility, Finland,.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.
Jan 01, 2003 In the flotation experiment of a converter slag (3.7 Cu, cooled in a refractory lined pit) with potassium amyl xanthate as collector, pine oil as frother at pH 8–9, a concentrate containing 44 Cu was obtained with 96 recovery. Co and Ni were also reported in tailings. In principle, copper slag flotation is the same as sulfide ore flotation.Copper Slag Flotation. Copper Slag Milling And Flotation Process Enhancing the flotation recovery of copper minerals in 01012020183 The following was used during the milling test work on the slag samples a laboratory scale ball mill 400 mm by 300 mm a Laarmann laboratory slurry press size 13 for slurry filtration a 1 0 L measuring cylinder for measuring and adding water a drying oven to dry.
In this study the effect of mixtures of copper slag and flotation tailings from copper mine Bor, Serbia on the flotation results of copper recovery and flotation kinetics parameters in a batch flotation cell has been investigated. By simultaneous adding old flotation tailings in the ball mill at the rate of 9 , it is possible to increase copper.Fig. 4 Development of copper stocks in Switzerland (2). With the planned recovery facility (copper from MSWI slag) the reservoir landfill should grow at a slower rate than is shown here. Shaded Standard deviation. Today, copper is still mostly obtained through open pit mining, rarely in underground mining or in-situ leaching.5 The.
Production of copper concentrate by flotation of smelter slag has started in 2001. Flotation concentrate goes to the Copepr Smelter once for production of cop-per 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 .Approximately 12 million tons of copper slag is produced every year, and the amount of accumulated waster copper slag reached 140 million ton by 2015 in China . Generally, copper slag contains about 35–45 wt. iron and 0.5–1.5 wt. copper, indicating that it is a valuable secondary resource for recycling and utilization .
Especially adapted to flotation of copper and gold ores in lime circuit. Non-frothing promoter. Minerec 27 Similar to Minerec A B Undiluted liquid .05 to .25 Powerful and selective collector for flotation of copper ores. Nacconol NR White flaky solid. Sodium alkylated aryl sulfonate. 1-5 solution. – to .5.The Influence factors of the matte smelting process,slag cooling method,cooling rate and slag composition on copper recovery in flotation are discussed.It is pointed out that slag cooling method and cooling rate are the main factors that affected the flotation recovery from copper slag.Taking sodium silicate as dispersant and inhibitor,and butyl xanthate and P3 as combinatorial collector.
Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests.In this study the effect of mixtures of copper slag and flotation tailings from copper mine Bor, Serbia on the flotation results of copper recovery and flotation kinetics parameters in a batch flotation cell has been investigated. By simultaneous adding old flotation tailings in the ball mill at the rate of 9 , it is possible to increase copper recovery for about 20 .

Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were.
2. Extraction of Metallic Copper. Concentration of the ore by froth floatation process Copper pyrites contains only (2-3) of copper. The rest of the ore contains iron or sulphide, silica, silicious materials, sulphur, arsenic etc. as impurities. Froth flotation by Xanthate and pine oil.Possible option. The copper slag contains a high content of silica and iron. The solution final pH is the most important factor affecting the removal of iron and silica from the leach solution and the overall metal recovery. Fe removal from the leaching of copper slag is done by the formation of a metal hydroxide.
3 6 6 of slag pyrite copper concentrate rate then roasting at 600 C at 5 hours. Besides, it was determined that all of Se, Te, Sb and As can be removed from the mixture of slag pyrite copper concentrate rate. Key words Copper, cobalt, slag, roasting, pyrite, copper concentrate. 1. Introduction Significant amounts of copper, cobalt and nickel.Apr 05, 2015 The content of copper in the flotation tailings directly depends on fragmentation rate (Figure 1). Expected content of copper in the flotation tailings, in the case of cooling in pits, is 0.5-0.9 , and in the case of cooling in pots, from 0.22 to 0.35 Cu. Fig. 1. The effect of fragmentation rate on the slag flotation .
Well as different techniques of froth flotation [2-6.8]. Flotation of copper slag is applied at industrial scale for decades and it is similar to the flotation of sulphide ores. In RTB Bor, in the industrial site of Copper Smelter and Refineries, 16-18 million tons of slag is de-.The second route was found to be suitable for the treatment of the copper slag studied. In the flotation step, a copper concentrate containing approximately 11 Cu was produced with a 77 recovery.
Nov 30, 2008 Copper slag wastes, even if treated via processes such as flotation for metal recovery, still contain heavy metals with hazardous properties posing environmental risks for disposal. This study reports the potential use of flotation waste of a copper slag (FWCS) as iron source in the production of Portland cement clinker.Some properties of a typical copper slag are shown in Table I, and it can be observed that air-cooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content, from 2.8 to 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption capacity of the.
Mar 19, 2017 The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65 silica, with pyrite, arsenopyrite, and calcite with 3 to 4 copper. This flowsheet, though simple, is adequate for tonnages of 100 to 500 tons or per day, depending on the size of equipment.1.2. Extracting Copper from Copper–Iron–Sulfide Ores. 1.3.
