Steel slag in China: Treatment, recycling, and management
Many restrictions exist, however, on the utilization of steel slag. When steel slag is used internally, in steel plants, the most obvious problem is that of the enrichment of P and S (Drissen et al., 2009).The Bhilai Steel Plant in India was shut down because of its high S and P content (Das et al., 2007).The amounts of free lime and free The aim of the present research work was to investigate the possibility of using steel slag as a raw material for the production of a typical Portland cement clinker. For that reason, two samples of raw meals were prepared, one with ordinary raw materials, as a reference sample ( (PC) Ref ), and another with 10.5% steel slag ( (PC) S/S ).

Environmental and Socioeconomic Impact of Copper Slag—A
Therefore, utilization of copper slag for recovering iron can be used to feed the steel plant, stimulating its resurrection. This can also help in the waste management of slag, thus reducing environmental pollution. Most slags contain 40 wt.% iron, and extraction of this iron from CS is ideal [ 70 ]. 2.2.results showed that depending on the source and composition of the steel slag s, the maximum CO. 2. sequestration after 4 days at 60 °C is reached as high as 300 kg per tonne for samples.Steel slag wastes to fight the climate change ResearchGate

Electric arc furnace granulated slag for sustainable concrete
According to EUROSLAG data [13], the production of granulated blast furnace slag was 23 million tons in 2012. The huge amount of EAF granulated slag increases the waste disposal costs, and therefore, the need for recycling of by-products for economic and environmental reasons is leading to the development of slag utilization.Isothermal reduction experiments on carbon-bearing pellets of copper slag were investigated by the thermogravimetric method with biomass carbon as a reducing agent. The results indicated that the reduction process of copper slag‑biomass composite pellets was dominated by gas phase diffusion, and the apparent activation energy was Isothermal Reduction Kinetics of Copper Slag‑Biomass Composite

Abstract. The current utilization rate of steel slag is only 22% in china, far behind the developed countries. At present, the amount of slag deposited in storage yard adds up to 30Mt, leading to the occupation of farm land and serious pollution to the environment. Improving the slag utilization is an important way to resolve these problems.Steel slag is a large discharge of industrial waste slag. Chinese effective utilization rate of steel slag is only 20%, causing great harm to the environment and economy.Physical and Chemical Properties of Steel Slag and
