The MgOFeOSiO2 slag is aggressive to refractory bricks, while the NiCuFeS matte is aggressive to watercooled copper cooling
The chemical composition of copper slag varies with the type of furnace. The typical composition of smelting slags is Fe (as FeO, Fe 3 O 4) 30–40%; SiO 2 35–40%; Al 2 O 3
The utilization of solid waste is the challenge for the civil and environmental engineers to utilize the waste from different industry to excel the sustainable
A range of slag textures is formed by differing cooling regimes and the resultant slag types exhibit varying properties. Aircooled slag, which is allowed to solidify slowly in ladles or
Slag reprocessing: Magma Copper Company’s San Manuel Facility. Converter Slag Slag Cooling stpd 9% copper Copper The rate of slag cooling and subsequent crystal
824 · The Effect of Bed Thickness and Cooling Time on the Rate of Copper Slag Cooling, Case Study: Khatoonabad Copper Smelter Plant Abstract Within the past few
116 · Slag cooling is an important process before slag beneficiation, and its technological scheme has great influence on slow cooling effect and beneficiation
Copper slag as sand replacement for high performance. Aug 01, 2009· Copper slag has a specific gravity of 3.4 which is higher than that for sand (2.77) and OPC (3.15) which may
Cu is the most important component in Cu slag, which is usually recovered by flotation. However, the crystalline state of Cu slag is not conducive to flotation, which limits the recovery of Cu. This study investigated the effect of Na2CO3 on the crystalline state of Cu slag and the recovery of Cu by flotation. The mechanism was investigated by
The copper slag is a complex metal containing substance. It mainly contains iron silicate and silicates of aluminum and calcium. and slag cooling rate (rapid cooling /granulation or slow cooling). All forms of copper slag (stones, granules and powders were assessed. 28 day TDp tests (Rodriguez et al., 2011) was performed on 2 samples
The utilization of solid waste is the challenge for the civil and environmental engineers to utilize the waste from different industry to excel the sustainable development, and in the same time, it is matching with the cost concern of the present materials. Copper slag is a byproduct obtained during smelting and refining of copper. The waste copper
a slag dump (shallow cooling pits) using slag haulers. Copper . 646. Figure 4 Kansanshi MSEF matte tapping floor (south), with tapping machine on left. Slag copper content is also
The copper slag is produced during manufacturing of copper that for every ton of copper production about 2.2 tons of copper slag is generated and 1.5 million tons of copper slag is generated in Korea every year [15]. Dumping or disposal of copper slag causes wastage of metal values and leads to environmental problems.
from hydrometallurgy processes, cooling water, air scrubbers, washdowns, stormwater, and sludges from wastewater treatment processes that require reuse/recovery or appropriate disposal. The main portion of the solid waste is discarded slag from the smelter. Discard slag may contain 0.5–0.7% copper and is frequently used

Converter Slag Slag Cooling stpd 9% copper Copper The rate of slag cooling and subsequent crystal growth was identified as a major technical factor » More detailed. Opta Minerals Ebonygrit Copper Slag. This cooling process fractures the slag into coarse and angular
Copper slag as sand replacement for high performance. Aug 01, 2009· Copper slag has a specific gravity of 3.4 which is higher than that for sand (2.77) and OPC (3.15) which may results in production of HPC with higher density when used as sand substitution. Also, the measured water absorption for copper slag was 0.17% compared with 1.36% for sand.
116 · Slag cooling is an important process before slag beneficiation, and its technological scheme has great influence on slow cooling effect and beneficiation indicators. At present, the technical scheme adopted in various copper smelting slag slow cooling plants have their own advantages and disadvantages.
Slag deposits, formed by fast cooling melts derived from silicate and carbonate copper ores, may be nearly ideal for paleointensity study. Many slag samples have portions that are very fine grained. Many specimens have magnetic particles that are extremely small, spanning the size range sandbed cooling of copper slag.
However, some copper matte is dispersed mechanically and entrained during slag tapping, and some copper dissolves in molten slag as cuprous oxide, resulting in a waste of resources [2]. It has been estimated that 2.2 –3.0 metric tons of slag is producedforeachtonofmetal[ 3];about46milliontonsofslag are produced annually in the
The cooling rate changes the abundance and type of copperbearing phases and affects the liberation of copperbearing particles from the slag [15] [16][17][42][43][44][45][46]. When the molten

Considering copper smelting slag as metal resource, we studied the effects of a slow cooling process on the crystal growth of magnetite in smelting slag and the applicability of magnetic separation techniques. As the cooling rate was lowered, the weight fraction of magnetite increased together with the average magnetite grain size.
The copper slag is produced during manufacturing of copper that for every ton of copper production about 2.2 tons of copper slag is generated and 1.5 million tons of copper slag is generated in Korea every year [15]. Dumping or disposal of copper slag causes wastage of metal values and leads to environmental problems.
indicating that about 1.5 million tons of copper smelting slag will be generated annually [24]. The copper smelting slag contains not only a small amount of the residual Cu which was not recovered from the smelting process but also SiO2, Al2O3, CaO, and 3545 wt.% of Fe. In Korea, the copper smelting slag is currently being simply
A CAD model view of a copper slag taphole set into a copper support cooler is shown in Figure 5. The tapping channel is initially lined with a suitable castable refractory, although this is eventually replaced by a layer of frozen slag (Joubert et.al., 2005). Both the faceplate and the copper taphole block can be replaced without entering
