Treated basic converter slag and a process for treating basic converter slag are disclosed, in which untreated slag in a molten state is subjected to an oxidation treatment and basicity adjustment treatment by the addition of a material containing SiO 2, so that iron or manganese components may be converted into forms which allow easy recovery thereof, and detrimental phosphorous components ...
Japanese steel mills treat steel slag with steam aging method, and the treated steel slag is used as upper subgrade material. The proportion of this material is 75% converter slag, 20% blast furnace slow cooling slag, and 5% blast furnace water slag. Germany has used converter slag to reinforce the Rhine ports and muz Banks. 4.
Dry slag granulation with heat recovery – Utilization of blast furnace slag heat energy ... primary waste gas treatment that is completely integrated. The main equipment for the LD (BOF) gas recovery is the gasholder plus the pressure boosters and distribution network. ... Converter waste gas cooling is highly challenging due to the tough ...
and treatment method using a rotary cooler as the main equipment. 2.2 Studies on slag treatment process Two types of slag stem from iron- and steelmaking processes: blast furnace and steelmaking slags. Various methods for granulat-ing blast furnace slag using water were developed since the 1970s, and its use as blast furnace cement rapidly ...

ing for their recovery. Slag can be used as construction material after nickel recovery, as appropriate (e.g., re turn of converter slag to the furnace). Sanitary sewage effluents require treat-ment in a separate facility or discharge to a mu-nicipal sewer. Modern plants using good industrial practices are able to achieve the pollutant loads ...
processing for their recovery. Slag can be used as construction material after nickel recovery as appropriate (e.g. return of converter slag to the furnace). Sanitary sewage effluents require treatment in a separate facility or discharged to a municipal sewer. Modern plants using good industrial practices are able to achieve the following in
Steelmaking slag includes the following: slag produced in the hot-metal pretreatment processes (desiliconization, dephosphoriza-tion, desulfurization, etc.), slag flowing out from the converter into the molten steel ladle, and slag formed during the secondary refining treatment (this slag is sometimes called "secondary refining slag" or
equipment for recovering copper from furnace slags. Pyrometallurgical production of copper generates two slags smelting furnace slag and converter slag which contain cu and cu, respectively the following three methods are generally utilized for recovering the copper from these slags on an industrial scale i recycling of the converter slag to the smelting furnace,
Feb 16, 2012· Potrerillos smelter uses Codelco Teniente Converter technology for further refining copper after the smelting. The slag from this process contains 8-11% of copper. In the new concentrator the slag will then be processed to maximize copper recovery and metallurgical yield. The new plant will process 1,700 tonnes of slag per day.
Jun 02, 2020· OOO Rosenergostal, Belgorod supplied this equipment. This is the third converter Primetals Technologies had modernized in the Chelyabinsk steel works. The other two converters were successfully brought into operation in August 2011 and November 2013. The Mechel Group is one of Russia's major producers of steel, ferrous alloys, coal and energy.
The Outotec PS Converting Process is the leading method for producing blister copper. Our process improves on conventional technology with a vessel structure that leads to better efficiency and emission-capturing systems. In the Outotec PS Converting Process, the molten matte from the smelting furnace is converted into blister copper.
capable of handling Isasmelt products and return slag from the Peirce-Smith converters producing a discard slag for disposal at the slag dump. • Installation of a single contact sulphuric acid plant to treat ~85,000 Nm3/hr of 9-16% SO2 tenor process offgas produced in the Isasmelt furnace for the production of 98.5% sulphuric acid.
Apr 17, 2014· CONARC process also has advantages when treating hot metal with higher phosphorus content (up to 0.2 %). Several aspects such as simple temperature control by adding DRI as coolant, addition of lime, as well as the withdrawal of phosphorus oxide rich slag by constant slag overflow via the slag door help to achieve an efficient phosphorus removal.
a shaft furnace. During the 1980s, a Slag Mill was built to re-process old copper reverbatory slags by converter techniques producing granulated slag, which is passed to the Pb smelter to recover Pb and also Cu. Since 1997, the Slag Mill has been used to re-treat converter slag tailings (Tsumeb Corporation Ltd., 1987; Schneider
Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. A now-uncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.
Pig Iron Production - Blast Furnace Route. More than 1.1 billion tonnes of blast furnace iron was produced globally in 2016. Blast furnace economics are such that larger units have lower unit production costs, hence there has been a trend to bigger and bigger furnaces. Modern blast furnaces produce more than 10,000 tonnes per day.
melting furnaces, pressure pour furnaces and magnesium treatment vessels with minimal to no adverse effects on refractory linings. Slag Formation: The formation of slag in the melting of ferrous metals in the foundry is inevitable. The composition of slag varies with the type of melting process used and the type of iron or steel being melted.
High Temperatures Technologies Corp. Canada presents the products based on plasma technology for different fields such as waste treatment, getting synthesis gas and other products. High Temperature Technologies Corp. offer ecologically pure technology which purpose is a full decomposition of the waste without harmful toxic substances and getting of useful products.
