iron and steel industry. The BSSF slag processing technology developed by Baosteel is a world lead technology for molten slag processing and Baosteel owns patent for the technology. The greatest features of the process is environment friendly, short process flow and resource reusable.
Jul 28, 2016· The recovered ironrich products are recycled back into the ironmaking and steelmaking processes to replace highcost steel scrap and iron ores. However, current slag processing is far away from optimum conditions, especially for slag fines with small particle sizes, resulting in generation of nonrecyclable "metallic" slag fines with ...

technologies to recover the iron value from BOF steelmaking slag and to divert the residual noniron bearing fraction into a feedstock for the manufacture of acid mine drainage (AMD) neutralizing agent. In this project, technologies are being developed to separate iron from the BOF slag and prepare those iron units for furnace charge.
to induce the grain growth of copper matte and magnetite by modifying the molten copper slag. As a result, it is effective to improve recovery and separation of copper and iron from the copper slag; meanwhile, the latent heat energy of the molten slag was effectively utilized and the energy consumption is also reduced. Therefore, the employment ...
PDF | A considerable amount of waste slag from the pyrite roasting process is produced every year. Recovery of iron from the waste slag is of great interest for maximum use of mineral resource ...
For BOF slag treatment, above mentioned pyrolytic selfslaking, HK, and BSSF processes are being accepted. No process considered the heat recovery from molten slag during granulation processes. Large scale application of stabilised steel slag powder in construction is a good way for steel slag .
Apparatuses, systems, and methods discussed herein facilitate processing of, and thermal recovery from, material such as slag. A disk assembly is configured to process material. One or more heat exchangers are configured to extract heat that is already present in the material, heat generated during processing, or both. A thermal transfer system is configured to transfer heat away from the disk ...
Abstract. To improve the efficiency of iron recovery from steel slag and reduce the wearandtear on facilities, a new method was proposed by adding a secondary screen sizer to the magnetic separation process according to grain size distribution of magnetic iron (MFe) in the slag.
Recovery of copper from smelting slag by sulphation roasting and water leaching 411 Materials and experimental methods Experiments were conducted using a reverberatory furnace slag from the Bor Copper Concentrator, Serbia. The slag was sampled from the crushing line before entering the milling section of the concentrator.
The present invention relates to a process for recovery of iron from copper slag. This invention particularly relates to a process for recovery of iron from a waste like granulated copper slag generated during the production of copper from its ores by a pyrometallurgical method. The present invention will be useful for solving the ecological and environmental issues with an added economic ...
A process to carry this out, using a DC arc furnace, has been under development at Mintek since 1988, and has successfully been demonstrated at pilot scale 1. The process involves the selective carbothermic reduction of the oxides of cobalt, nickel, and copper, while retaining the maximum possible quantity of iron as oxide in the slag.
By using DR followed by a magnetic separation process for iron recovery from copper slag, Yang obtained iron powder of % iron content with an iron recovery rate of %, and Wang obtained iron powder of % iron content with an iron recovery rate of %. Both of their tests have achieved good results.
separation process for iron recovery from copper slag, Yang [10] obtained iron powder of % iron content with an iron recovery rate of %, and Wang [11] obtained iron powder of % iron content with an iron recovery rate of %. Both of their tests have achieved good results. However,
The present invention provides a method of separating and recovering iron from a waste nonferrous slag, generated in a process for smelting of nonferrous metals, including copper, zinc and lead, in which a reducing agent and a reaction catalyst are added to the crushed waste nonferrous slag, and the mixture is subjected to a reduction reaction, thereby converting amorphous iron oxides ...
properties and their optimum combination. As far as the BOF slag processing is concerned, the consists in achieving a product with higgoal,with the h iron content final objective of slag reuse in sintering process. The iron separation from slag allows ironrecovering as a substitute for scrap as well as, making effective use of the slag for
temperature, slag basicity, and magnetic field strength on recovery and grade of the concentrate were investigated and optimized oxidation of iron monooxide (FeO) to magnetite (Fe 3 O 4) and other spinel ferrites in RO phase was observed. Solid state oxidation achieved overall optimum

The recovered dust (Waelz oxide) is enriched in zinc oxide and is a feed product for zinc smelters, the zinc reduced byproduct is known as Waelz slag. Suboptimal features of the process are high energy consumption, and lack of iron recovery (and iron rich slag).
Many technologies are leveraged in a blast furnace to enhance iron making yield, throughput and hot metal quality such as modern tuyere and oxygen injection designs, refractories with improved iron and slag resistance, improved burden feeders, gas and energy recovery and advanced process .
Iron and steel slag refers to the type of metal manufacturing slag that is generated during the process of manufacturing iron and steel products. The term "slag" originally referred to slag produced by metal manufacturing processes, however it is now also used to describe slag that originates from molten waste material when trash and other ...
