how generated iron slag egypt

Oct 29, 2019 Slag is the by-product of iron- and steelmaking processes. Normally, around half to one tonne of slag would be generated for yielding one tonne of rolled iron or steel (Lobato et al. 2015).It was reported that the world steel production was 1.9 billion tonnes in 2016, which suggested that at least around 1 billion tonnes of slag is produced during the year (Worldsteel Association 2016).

Red mud (RM), the by-product generated during the alumina extraction process, is considered a valuable second-ary raw material, since iron (2054%) represents its major constituent. Accordingly, the suitability of recycling this RM in the sintering process of Egyptian iron ore was studied. The effect of adding different amounts of RM

Blast furnace slag is a non-metallic by-product from iron and steel industry. The generation of blast furnace slag takes place during the conversion of iron ore or scrap iron to steel, along with coke for fuel. Production of one tonne of steel leads to the manufacturing of500700 kg of slags. The molten slag comprises about20% by mass of iron We bring forth a wide range of custom made Cast Iron Slag Pots.
