The growing demand for nickel metal and the depletion of high-grade sulfide ore reserves have turned direction industry towards laterites which are not desirable as primary source due to their low Ni content more energy-intensive processing. Thus, alternative routes essential effectively processing these ores while reducing costs greenhouse gas emissions. Solid-state reduction followed by magne...

The formation of intragranular pores, induced by diopside crystallization in diopside–albite glasses, was highlighted in a previous study and here confirmed by SEM observation. The sinter-crystallization kinetics of four glass compositions, labelled G1, G2, G3 and G2-Cr, characterized by the formation of induced crystallisation porosity, PCR, was investigated. The activation energies of crystal...
