metallurgical waste generation is through recycling. Slag recycling has been successful in a variety of industries, for example, ironmaking and steelmaking. However, some industries are still challenged with efficient utilization of large quantities of generated slags. This paper summarizes the characteristics of different slags and their utilizations
Use of Slag. Slag plays an important role in industrial production, especially in some large factories, slag is extracted and processed into slag cement, slag fine powder, slag powder, slag Portland cement and slag cotton. Blast furnace slag can also be used as raw materials for cast stone, glass-ceramic, fertilizer, enamel, ceramics and so on.

27-04-2014· In this study, recycled Ni smelter slag has been used as a reactive medium for arsenic (As) removal from aqueous solutions. The results of the study showed that 10.16–11.43-cm long columns containing 451–550 g of slag operated for at least 65 days were able to remove 99–100 % As species from continuously flowing contaminated water at an initial As concentration of 10 mg/L. The removal ...
29-07-2014· Recycling slag minimizes waste and disposal costs, reduces energy use, extends furnace life, and lowers the amount of additives needed to make slag. The concerns with slag recycling are that first, because slag can contain environmentally hazardous materials, it must be analyzed for elemental composition before reuse.
recycling evaluated in the present study mainly consists in the reuse of the ladle slag and refractory, injecting them into the Electric Arc Furnace. The recycling of ladle slag can permit to achieve interesting advantageous results: decreasing the amount of dumped material, the cost of EAF fluxes and improve the slag iness.
11-10-2018· RECYCLING POSSIBILITIES OF THE SLAG FROM CUPOLA FURNACE. The cupola furnace is a most widely used foundry furnace for melting of cast iron. Besides main product, cast iron, also secondary products are formed in cupola furnace. They have a character of secondary raw materials, or industrial wastes. Under the laws applicable to waste management ...
Ferrous industry slag is waste product of all steelmaking manufactures. These materials should be reused or stocked. There is abundant literature on the subject of reuse and recycling of blast furnace(BF), basic oxygen furnace(BOF), electric arc furnace(EAF). However, due to the fact that ladle furnaces(LF) have only been constructed in significant numbers since the 1980's, the relatively low ...

Abstract A large volume of slag is generated as a by-product during steel manufacturing. In order to ensure environmental and economic sustainability, it is imperative to find innovative solutions for the efficient recycling of slag. This review broadly and critically explores the available information concerning the effective recycling of slag in agriculture and its potentials in crop yield ...
Slag contains reusable lime and metallic scrap that can be reused, in addition, being able to completely recycle it will save on cost of fuel, dumping, and transportation. The company STEIN Injection Technology developed a way to separate lime for the scrap and convert it in to usable wire injection that can once more be used to create clean steel.
