A novel hydrometallurgical approach to recover valuable metals from laterite ore

Effect of Ni substitution content on structure and magnetic properties of spinel ferrites synthesized from laterite leaching solutions

“…In our previous work, by using an atmospheric acid leaching-coprecipitation-calcination method, Ni-Co-Mn co-doped MgFe 2 O 4 were firstly and directly synthesized from saprolite and limonite laterite blends leaching solution. The saturation magnetization (Ms) and coercivity (Hc) values of as-prepared ferrite were 29.6 emu g À 1 and 45 Oe, respectively [10], suggesting that ferrites with multicomponents can improve the magnetic properties. Till now, many efforts have been taken on obtaining high saturation magnetization and reasonable coercivity.…”
