The paper considers one of possible options for the waste-free processing dumped masses nickel slags, accumulated over years operation some enterprises. This process includes use hydroand pyrometallurgical processing, which results in three products: iron sulfate, ferrosilicon with a small admixture aluminum, and slag from smelting. has hardness 7-7.5 Mohs can be used as an abrasive powder sand...

To improve the yield of titanium alloy, a certain amount TiO2 can be added to refining slag system Ti-bearing steel grades. With aim understanding effect addition on melting behaviors CaO-SiO2-30%Al2O3-5%MgO slags, points slags and phases in are herein studied at different temperatures laboratory. It is found that with increase content (0~10%) slag, point drops first, then rises. The basicity (...

An assessment of the possibility steel direct microalloying with cerium was performed using thermodynamic modeling reduction from slags CaO– SiO2– Ce2O3 system containing 15 % Al2O3 and 8 МgO, additional additives reducing agents (aluminum or ferrosilicoaluminium), at temperatures 1550 1650 °C HSC 6.1 Chemistry (Outokumpu) software package. Depending on aluminum ferroglycoaluminium, metal tempe...

The effects of chemical oxides and the surface area (SA) slags on initial reactivity alkali-activated materials (AAMs) are coupled. It is well known that slag in AAMs impacted by SA, however, a quantitative measure this effect was not provided previous studies. For proper understanding chemistry reaction kinetics AAMs, description SA's required. activated were monitored using isothermal calorim...

This study explores mineral carbonation of industrial stainless steelmaking slags and relevant synthetic constituent minerals via in situ pressurized X-ray diffraction, to clarify reaction pathways efficiency for carbon storage waste valorization. The primary phases Argon Oxygen Decarburization (AOD) Continuous Casting (CC) slags, namely, åkermanite, bredigite, cuspidine, merwinite, β- γ-C2S, w...

The possibility of utilizing non-ferrous slags for CO2-mineralization is explored in this study by investigating their dissolution behaviors CO2-environments, since usually considered as a major rate-limiting step during CO2-mineralization. Dissolution two copper and lead slag are studied at the liquid to solid ratio (w/w) 1000 combinations temperatures (30 60 °C) CO2-pressures (1 10 barg) with...
