In this study, the valorization potential of Polish laterite leaching residues through alkali activation with use NaOH and Na2SiO3 solutions as activators was investigated. The effect main factors, namely H2O/Na2O molar ratio in activating solution, curing temperature, ageing period on properties produced activated materials (AAMs) assessed. experimental results showed that AAMs sufficient comp...

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 permian deposits in the stratigraphic section of sangsar (located in the eastern alborz), are the best expose in the semnan area. this sequence consists of the doroud (asselian-sakmarian), ruteh (artinskian-murgabian) and nessen (early djulfian) formations. the dorud formation in the studied section with 56 m thickness consists of conglomerate, sandstone and quartzite, which is disconformit...
