The carbothermic reduction roasting followed by ammoniacal leaching of a Ni-laterite ore
from Bajaur (Pakistan) has been studied first time for its potential exploitation via the Caron …

Critical metals, defined as metals with growing economic importance that might be
susceptible to future scarcity, are present in industrial waste waters. However, they are …

The presence of iron in pregnant leach solutions (PLS) is a common problem, and is
generally removed using jarosite, goethite, hematite or para-goethite precipitation methods …

The Caron process involves the roasting of nickel laterite ore at 750° C with fuel oil to
produce a calcine containing Fe-Ni-Co alloy and other reacted or unreacted host minerals …

Carbothermic reduction-roasting of a low-grade Ni-lateritic was investigated under the
modified Caron process. Roasting parameters of reductant (coal), additive (Na 2 SO 4) …

The purification of hydrometallurgical process solutions by Fe (III) precipitation is a common
and large-scale industrial operation. This step is notorious for valuable metal loss occurring …

It is shown that thermo-kinetic Eh-pH diagrams can be generated through electrochemical
measurements. These diagrams offer an accurate method of determining stability regions for …

The paper focuses on leaching of complex copper–cobalt–nickel ore from Mwinilunga
district in Zambia, containing 0.6% Cu, 0.21% Co, 2.6% Fe, and 0.13% Ni. Mineralogical …

Ferric iron precipitation is an important integral step of the hydrometallurgical processes.
The precipitation product is often amorphous and leads to a significant amount of valuable …

The recovery of iron is the key step for zinc recycling by electrolysis in zinc hydrometallurgy
industry. Iron exists mainly as ferrites in the zinc neutral leaching residue and is difficult to …
