Slag recycling recovery

With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron. In the case of inferior grade ores below 60 %, the amount of slag is typically 0.35 to 0.50 slag/t of pig iron [1].

The recycling and reuse of steelmaking slags — A review

2019-7-1  During sintering, fine iron ore particles are mixed with a small amount of coal (5% by weight), and the mixture is then ignited (Peters, 1982).The process is driven by the decrease in surface energy (surface area) that causes the edge of the particles to fuse together ().The particles produced in this manner have a lower density than particles produced by a pellet

Sustainable recycling of iron concentrate obtained from

1. Introduction. The iron concentrate is a product of the hydrometallurgical processing of uranium ore. As it contains up to 65% of iron, it can be used as a raw material for ferrous metallurgy (Fernández-González et al., 2017).Recycling of iron concentrate can provide significant financial profit compared to the existing schemes of slag processing which include the introduction of a

Iron Recycling Cohen

Iron ore most commonly, hematite and magnetite goes through a process known as sintering to create pieces that are 10-25mm in size. These pieces enter the furnace along with coal (known as “coke” in this context), which provides the heat, and limestone, which makes any impurities in the ore rise to the top to form a layer called slag .
