PSC launders which feed the furnace on the east. Slag is tapped via forged copper launders into 50 t slag ladles and transported by Kress hauler to a remote slag dump. The slag tapholes are opened and closed during tapping campaigns over the course of a day. Tapping campaigns may last several hours, during
13/01/2021 · Copper Smelting Process. In the autogenous system described by this report, sulfide concentrate and silica flux are blown into the furnace through a specially designed burner with oxygen and is flash smelted to about 50percent copper matte. The matte flows down an inclined crucible, countercurrent to the slag flow, to the converting zone at ...
01/06/2017 · Slag systems are usually studied with reference to CaO, SiO 2 and Al 2 O 3 content. Fig. 2 shows the ternary phase diagram of CaOSiO 2Al 2 O 3 system (Levin and McMurdie, 1975).In this figure, the chemical composition of the initial copper slag sample investigated is also shown along with that of a typical Blast Furnace (BF) slag.
Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.
The copper content of the slag is maintained at to percent Cu by maintaining a reducing atmosphere in the slag cleaning furnace. The slag then flows by gravity to the converter furnace. The converter furnace produces anode copper which flows to a holding furnace prior to anode casting. Slag from the con verter furnace is granulated ...
14/02/2020 · Copper slag is produced during the manufacturing of copper, and for every ton of copper production about tons of copper slag are generated, and million tons of copper slag are generated in Korea every year [1–5]. Dumping or disposal of copper slag causes wastage of metal values and leads to environmental problems.
slag depletion and lead to significant irreversible losses of metal with slag. Therefore, ways to reduce the loss of copper with slag in the process of autogenous smelting are becoming increasingly important today. RESEARCH METHODOLOGY The samples of the slags were obtained from Vanyukov furnace in Balkhash CopperSmelting Plant. They
Copper slag is a byproduct of copper production from copper ore. For every ton of copper produced about ton of slag is generated. At present, across the world around 33 tonnes of slag is generated while in India three copper producers Sterlite, Birla Copper and Hindustan Copper produce around tonnes of slag at different sites.
Copper slag is a byproduct obtained during smelting and refining of copper. Copper smelting slag typically contains about 1 wt.% copper and 40 wt.% iron depending upon the initial ore quality and the furnace type. Main components of copper slag are
