The slag from the smelting furnace is subjected to the electric slag cleaning process, which comprises two stages. In the first stage the Cu in the slag is reduced by coke from 18% Cu to 5% Cu and in the second stage it is further reduced to recover the metal values in the form of CuFeCo alloy.
Nov 29, 2018· 10 things you can clean with CocaCola. Sure you can drink CocaCola, but it also happens to be a great way to clean items around your house.. .
The State–oftheArt Clean Technologies (SOACT) for Steelmaking Handbook reduce environmental impacts in the steel industry. Its purpose is to share information about commercialized or emerging technologies and practices that are currently available to increase energy efficiency and .
DCarc furnace technology has been successfully applied to the recovery of cobalt, nickel, and copper from nonferrous furnace and converter slags. Pilotplant testwork at Mintek has demonstrated recoveries of 98% for nickel and over 80% for cobalt, at power levels of up to 600 kW.
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.
Pulverised coal injection (PCI) is a well established technology. It is practised in most, if not all, countries with cokebased BFs, and new BFs are nearly always fitted with PCI capability. Waste plastics injection (WPI) is less Injection of coal and waste plastics in blast furnaces 5 commonly carried out, with only a few ironmaking plants in
May 10, 2013· Pulverized coal injection in a blast furnace Pulverized Coal Injection (PCI) is a process that involves injecting large volumes of fine coal particles into the raceway of a blast furnace (BF). This provides not only a supplemental carbon source but also speeds up the production of liquid iron besides reducing the need for metallurgical coke for ...
A cupola or cupola furnace is a melting device used in foundries that can be used to melt cast iron, Niresist iron and some cupola can be made almost any practical size. The size of a cupola is expressed in diameters and can range from to 13 feet ( to m). The overall shape is cylindrical and the equipment is arranged vertically, usually supported by four legs.
flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the blast air to form molten reduced iron, carbon monoxide (CO), and slag. The molten iron and slag collect in the hearth at the base of the furnace. The byproduct gas is collected through offtakes
Coal for metallurgical coke production: predictions of coke quality and future requirements for cokemaking ... coke rate by high levels of injection of carbon via the tuyeres, in particular pulverized coal injection (PCI), ... productive part of coke which influences slag volume and composition. Industrial experience indicates that a
The initial study to control the coal rate injected into a slagcleaning furnace (SCF), based on a soft sensor, was developed at Caletones Smelter, Chile. The old estimation algorithms were only based on discharged cycle average information, leading to large prediction errors.
Optimum slag viscosity • The most important factor affecting slag viscosity is the presence of suspended second phase particles (MW C2S) in the slag FeO content of the slag • Sufficient FeO in the slag is required to react with carbon and generate CO gas bubbles • Too much FeO is equated with iron loss MgO content of the slag
In parallel test runs in the pilot scale EAF of IME have been conducted in order to demonstrate the feasibility of a slag cleaning treatment by coke injection. It has been found that the process ...
Adding 12 lbs. of flux per ton of molten metal is sufficient to cleanse the metal, remove slag, prevent buildup formation on furnace walls, on channel furnace / pressure pour inductors. Slag/Dross Inclusion Elimination Case Histories . Foundry A melts both gray and ductile iron in several large channel and coreless melting furnaces.
injection and replacement ratio for coke is the selected PC type for injection. The volatile matter (VM) content as well as ash composition and amount is important factors. From economical point of view flexibility in the use of different types of PC is important and alternative coals have to .
zA slag cleaning treatment with metal recovery is necessary for ecological and economical reasons zAt the IME the intensification of slag cleaning of lead/zinc and copper slags in the EAF by coke injection is investigated, including injection trials in a water model and test runs in the pilotscale EAF
