The synthesis of foliar and Ca‐S‐Si compound fertilizers using titanium‐bearing blast furnace slag, potassium bisulfate, citric acid, carbamide, and magnesia as raw materials is reported for the first time. This synthesis enhances the solubility of the slag and transforms the nutritional elements into such forms as to be more readily absorbed by plants.
Calcium carbonate (CaCO 3) is a fine white powder used in the paper industry as a pigment for coated papers. thyssenkrupp Steel is working on an innovative process to extract this high-purity material from steel slag and also investigating to what extent surplus CO 2 from the production process can be used for this – a further step on the way to the climate …
Blast furnace slag and phosphate fertilizer could effectively promote Pb to transform from nonresidual fraction to residual one, thereby reducing the bioavailability of Pb resulting in the passivation of soil Pb.
The quality of raw materials (iron ore, coal, and coke) has a clear impact on the carbon emissions of the hot metal production in steel making. So far, very little work has been done to measure and quantify this impact. Yet for benchmarking, technology choice and general carbon optimization are important elements. The total slag …
Introduction. China is the world's largest steel producer, with the China Iron and Steel Association estimating that the country's crude steel production in 2022 will be 935 million tonnes [Citation 1].Steel slag mainly refers to the blast furnace slag and converter slag produced in the process of iron making and steel making, and with the …
The raw materials adopted in the experiment mainly include kaolin clay (KC), blast furnace slag (BFS) and municipal sludge (MS), which were collected from Shanxi Huayang New Material Group, Henan Platinum Run Casting Material Co., Ltd. and Shanxi Yangquan Wastewater Treatment Plant, respectively.
