Nickel plays a critical role in the mining industry. However, presence of nickel primary source sulfide minerals is decreasing. Focus has since turned to laterite ore, which contains up 80% Ni metal. The purpose this study was optimize leaching using sulfuric acid and conduct kinetic analysis discover mechanism that best controls process. To operating conditions, response surface method (RSM) w...

Abstract This study sought to use the stress–strain relationship of interlocking stabilized soil block (ISSB) masonry model its behaviour and develop empirical formulae aid in predicting compressive strength. A finite element (FE) analysis adopting Rankine failure criterion was performed using Abaqus software simulate deformability wall which validated through experimental tests. The strength, ...

In this work, two different laterites (iron contents of 13.07 and 49.34 wt%, respectively, for lateritic clay, LAC, iron-rich laterite, LAI) were selected calcined at 600 °C. The obtained laterites, namely LAI600 LAC600, separately mixed with an alkaline solution (silicate modulus 1.35) or acidic (phosphoric acid pH ≤ 2) the synthesis inorganic polymer products. fabricated products cured 20 °C ...
