The recycling and reuse of steelmaking slags — A review …

The first step of the pelletizing process is known as balling.The ore is mixed with a binder (bentonite clay), and then placed into a rotating drum with excess water. Where the particles come into contact, a liquid bridge between the particles is formed (); capillary suction occurs which bonds the particles together, first by flocculation and then agglomeration until small 'green' balls are ...

Recycling Ladle Furnace Slag as Flux in Steelmaking: A …

LF slag recycling was tested at JSW Steel, Vijayanagar Works, India by means of Al-killed ladle furnace slag as a replacement to synthetic slag. The recycling process was carried out in two steps. Even though the composition of LF slag is similar to calcium-aluminate-based synthetic slags, composition of dump slag varied due to the addition of silica-based ladle-covering compound (LCC) in ladle.
