Crystal morphology is controlled by several physicochemical parameters such as the temperature, pressure, cooling rate, nucleation, diffusion, volatile composition, and viscosity. The development of different crystal morphologies observed a function rate in many rock types (i.e., glassy volcanic rocks, archeometallurgical slags). Crystallization two-stage kinetic process that begins with format...

Dissolution of diopside-bearing slag and its amorphous counterpart was investigated to decipher recovery potential these slags. The contribution direct phase dissolution using a biotic solution with Acidithiobacillus thiooxidans versus sterile growth medium, whereas citric acid applied demonstrate slags in organic medium. Potential metal donor phases easily released elements were identified by ...

The oxidation balance is arguably one of the most important parameters during pyrometallurgical processes. In many cases, iron abundant multivalent element present in silicate slags. Within these molten oxide mixtures, oxygen dominated by relative fractions Fe3+ and Fe2+ present. Measuring concentration ferrous ferric quenched slags can provide useful information about state liquid slag at mome...

The recycling options of spent MgO-C refractories from an electrical arc furnace (EAF) have been evaluated. The economic, quality of spent refractories and products made from it, the ease of implementation of a recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a foaming sla...
