In response to the pressing global issue of reducing carbon emissions and the crucial technical challenges of fully utilizing steel slag, researchers have been studying an accelerated carbonation process that entails the carbonation of basic oxides in steel slag to store CO2. However, despite its promising potential, the process has yet to see …

The magnetic steel slag washing, ball mill, magnetic separation, purification process, comprehensive recycling technology of slag and complete set of equipment can not only realize water recycling, but also the purification grade of steel slag is high (TFe > 90%), and the taste of iron-containing slag powder is up to 55%.

Steel slag (SS), a waste product of steel manufacturing, accounts for approximately 15% to 20% of global steel production. Unfortunately, most of the steel slag has not been effectively recycled but rather disposed of through landfilling or stockpiling.

But slag itself has value, and technologies have emerged to recycle and reuse reprocessed, granulated slag in different building materials, such as cement, brick, …

Today, cement and concrete are some of the most consumed materials after water throughout the whole world. About 4.1 billion tons of cement are fabricated annually (half a ton per person) and half of this amount is produced by China [5].In addition, >1 m 3 of concrete per person is produced with Portland cement each year [6].Today, …

With the rapid development of China's steel industry, rising rates of steel production have led to the increase of steel slag emissions.
