Experimental studies have shown that[4], after grinding and screening of steel slag, chemical analysis is carried out on the sieve residue, and the screened substance is basically iron metal. Therefore, the poor wear resistance of steel slag is mainly due to the inclusion of metal iron rather than the mineral itself. 3.

cement - cement - History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in western Europe.
Values of CaO% and MgO% are 65% and 1.2% derived from the projects studying CO 2 emissions in China's iron and steel, chemical and cement industries conducted by Chinese Academy of Engineering . Values of EFca and EFmg are 0.785 ton CO 2 /ton and 1.092 ton CO 2 /ton derived from decomposition reaction of carbonate.

A high temperature stage microscope to investigate the temperature effect caused by particle size on char gasification is applied in this study. Experiments were carried out with different particle sizes for raw chars and chars on molten slag surface, respectively. Heat transfer models were built for the raw char of two temperature distributions and char particle on molten slag, respectively.

The magnesium slag is rich in Ca, Mg, Si elements, in which most of the arable land in China is deficient. Based on this, a new process for producing calcium-magnesium-sulfur-silicon(Ca-Mg-S-Si) fertilizer with magnesium slag is put forward by grinding and acid treatment. It is indicated from the trial production test that the optimum grinding diameter is about 60μm to producing the Ca-Mg-S ...

A large number of unexploited low-grade vanadium-titanium magnetite deposits have been found in the Chao-yang area of China in recent years. The reserves are estimated at more than 20 billion tons. A mineralogical study of raw sample indicated that it was a typical low-grade vanadium-titanium magnetite ore with weathering. Most of vanadium-titanium magnetite was replaced by martite and …
Crystallization behavior, liberation and beneficiation of Ti-rich phases precipitated from Ti-bearing slag of smelting process for titanomagnetite were systematically investigated. For the slags containing 40–55 % TiO2, anosovite can precipitate as the main Ti-rich phase, especially as the TiO2/MgO/Al2O3 content is relatively high and basicity [R = w(CaO)/w(SiO2)] is low.

b University of Chinese Academy of Sciences, Beijing 100049, China Abstract The titanium-bearing blast furnace slag (BFS), a solid waste with high TiO 2 content (around 20%) and huge production (3.6 million tons per year), has caused serious environmental problems in China.
Conventionally, little chemical adjustments are made to the slag prior to its processing for subsequent use or disposal. However, recent attempts have looked into modifying the chemical composition of slag while hot, to render its chemistry and properties suitable for high-value products or recovery of minerals/metals from slag [11, 12].Nonetheless, the majority of slags are processed by ...
