Chemical recycling of municipal waste slag by …

A chemical recycling method by using phase separation was applied to municipal waste slags. Glasses were prepared from incineration ash and ash-melted slag, where B 2 O 3 was added to promote phase separation. The glasses were heat-treated at temperatures higher than their glass transition temperatures, and they were soaked in hydrochloric acid, leaching CaO, Fe 2 O 3, K 2 O, and S ...

RECYCLING OF STEELMAKING SLAG FROM ELECTRIC ARC FURNACE

Composition of the slags taken in the first part of the trials is in Table 1. It can be seen from the table, that reference heats produced without demetallized slag additions have higher contents of Al 2 O 3, SiO 2, P 2 O 5 and lower contents of FeO. Additions of demetallized slag didn´t increase the phosphorus and sulphur contents nor in steel nor in slag. Structural composition of slag was ...

Study on Recycling of Steel Slags Used as Coarse …

Steel slag, a by-product of steelmaking, imposes lots of negative impacts on the environment. For alleviating negative impacts, more and more experiments have been carried out to explore the application possibility of steel slag. The purpose of this study is to explore the feasibility of steel slag being applied in induction healing asphalt concretes to replace coarse and fine aggregate.

Recycling of municipal waste slag using phase separation ...

slags are colored black. If Fe 2O 3 is selectively removed from the slags, colorless glass should be obtained, which is expected as an ingredient of plate glasses. It will be a new recycling route of waste slags. In the present study, a novel removal method of Fe ions from waste slags has been developed, where phase separation of glass was used.

Slag - Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...
