Processing of Granulated Blast Furnace Slag and its applications. Leave a reply. Granulated Blast Furnace Slag (GGBFS, or GGBFS, or BFS) is the most used material in cement industry to make slag cement. ... While this coloration effect seldom occurs, it is attributed to a complex reaction of the sulfide sulfur in the GGBFS with other compounds ...
Abstract. Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD.
STEELMAKING SLAG: A SAFE AND VALUABLE PRODUCT Page 3 Producing BF, BOF, and EAF slags is an important step in the iron/steel making process. During this process, substances that are incompatible with iron and steel are removed by forming complex metallic and nonmetallic oxides. Chemically, steelmaking
The slag after crushing and grinding is fed to autoclave leaching. The optimal conditions of the leaching process, contributing to the full opening of the slag and extraction of germanium and zinc in the solution are: the lye concentration 20 wt.%, process temperature 200÷220°With the ratio of the phases W:t=5, time 60-90 minutes.
Copper processing - Copper processing - Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or ...

Processes for metal recovery reach from fairly simple to highly complex – depending on the value and content of the metal in the slag on one side, and on the desired application for the residual slag on the other side. Process types might be grouped into. Simple crushing and screening processes for coarse metal recovery
A hydrometallurgical process for treating slag material, especially copper smelter slag material, comprises vigorously mixing the slag material with about one part by weight of sulfuric acid and about one part by weight of water for each part by weight of the slag material, and allowing the resulting mixture to react to produce a dry, solid material, containing the metal values of the slag .

Fuming furnace is also installed to produce zinc Oxide from blast furnace slag. Certifications. Dariba Smelting Complex is ISO 9001 certified and pursuing IMS certification. Process Description Roast Leach Electro-winning (RLE) The hydrometallurgical smelting process is a roast, leach and electro-winning (RLE) process.
Bushveld Igneous Complex are used. Quartzite is added as flux, and coke is used as reductant. The chemical composition of quartzite and coke are listed in Table II. Based on the production of ferrochrome in South Africa, the following conditions are used as major smelting parameters: 6% FeO in slag 12% Cr 2 O 3 in slag
of much improved mechanical properties of the steel. In these revised process routes, slag of different compositions are produced in the variety of unit processes and hence the re-use of steelmaking slags has become much more complex. Clearly, a thorough understanding of the
with given ladle slag compositions.9,14 For real industrial conditions, the wear of the slag lining is a complex process involving different mechanisms as mentioned above. As a consequence, a complete study of the corrosion process of the refractory requires a combina-tion of both the thermodynamics and kinetics of re-fractory degradation.

Aug 01, 2015· Role of Slag in Converter Steelmaking. The oxygen converter process is the primary steelmaking process for the production of carbon and low-alloy steels. The process is essentially an oxidizing process of refining of the high carbon hot metal (HM) to low carbon liquid steel. The oxidizing process is carried out by blowing oxygen in the converter.
