Slag was prepared from two kinds of copper furnace: Reverb from Sarcheshmeh copper Complex and flash furnace. There is about 1% copper in the slag of converter furnace which transferred to reverb one to obtain. Then it is exposed to the weather and cooled down after exiting the furnace. But in the Flash furnace at the copper factory of
Keywords: copper blast furnace slag, compressive and tensile strength of concrete 1. INTRODUCTION Concrete is a construction material composed of cement as well as sand and aggregate. Today the usage of pozzolans either natural or artificial has been increased. One of these artificial pozzolans is the slag of metal melt furnace such as iron, copper, etc. several researches on iron slag have
The presence of copper in reverberatory furnace slag is accepted as being due to two factors: chemically dissolved copper and mechanically entrapped matte. Beyond this fact, however, opinions on the nature of the materials involved begin to diverge. A sample of flotation recleaner concentrate from the pilot plant assaying % Cu was used for microprobe analysis of the copperbearing phases
Copper slag furnace slag copper. Copper slag that is derived by smelting of copper concentrates in a iron, which is added to the furnace charge, combines with phosphorus to form recovery of copper from copper blast furnace slag request pdf nov 6, 2018 secondary copper blast furnace sl.

Copper slag granulated by water quenching produces vitreous amorphous solid particles that show higher chemical stability than those aircooled solidified (Pavéz, Rojas, Palacios, Nazer, 2004). The chemical composition of copper slag varies with the type of furnace.
· Copper slag is a byproduct created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of nonmetallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
· Copper slag has been carbothermally smelted in a submerged electric arc furnace, partially reducing FeO to a metallic phase comprising of copper and other metals by Acma et al. (1992). The metallic phase has been transformed to the granules by passing through an air jet. The granule after grinding was leached with H
Copper Slag During the process of copper smelting and refining, impurities or slag is separated and floats on the metal surface. This waste generated by the blastfurnace during copper extraction is converted into a lowcost adsorbent called Copper Slag. Milling And Flotation Of Slow Cooled Copper Slag
Shaft furnace is high efficiency equipment with high heatavailability factor of fuel consumption due to material and gases opposite flow within the furnace. The main purpose of slag processing is extraction copper out of copper, brass and bronze slag fractions of 30 – 100 mm with copper content not less than 5 %, receiving molten metal and pouring it into moulds or a ladle.

Such conditions include operating the electric furnace at metallic copper saturation, maintaining the %Fe in the electric furnace matte between 6 wt.% and 9 wt.%, not exceeding a slag temperature of 1250°C, and controlling the Fe/SiO 2 ratio in the smelting furnace slag at ≤ In addition, magnetite reduction needs to be performed efficiently during the slagcleaning cycle so as to
The authors further consider that under exceptionally wellcontrolled conditions, a copper content in electric furnace discard slag between wt.% and wt.% can be obtained, by minimizing
This chapter discusses the nature of copper in smelting and converting slags. It also describes strategies for minimizing the amount of copper lost from their disposal. Cu smelters produce two
Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed. Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature. The slag forming reaction is: FeO + SiO 2 → 2
SHAFT SLAG FURNACE (SSF) Shaft furnace is high efficiency equipment with high heatavailability factor of fuel consumption due to material and gases opposite flow within the furnace. The main purpose of slag processing is extraction copper out of copper, brass and bronze slag fractions of 30 – 100 mm with copper content not less than 5 %, receiving molten metal
in a DCarc furnace. This technology is applicable to the recovery of nickel, cobalt, copper, and platinum group metals from furnace or converter slags emanating from copper or nickel smelters treating sulphide concentrates. Pilotplant testwork at Mintek has demonstrated
The recovery of copper from smeltery furnace slag by flotation has been studied. by analysis the slag containing copper and silver is available to recovery. the effective factors such as particle size, the amount and type of collector were examined. the combination of the collectors was also examined. with the process utilized in this work, a copper concentrate of cu with
· Copper slag, which is produced during pyrometallurgical production of copper from copper ores contains materials like iron, alumina, calcium oxide, silica etc. For every tonne of metal production about ton of slag is generated. Dumping or disposal of such huge quantities of slag cause environmental and space problems.
