The reductive leaching of nickel laterite has attracted the interest of many researchers due to
the enhanced kinetics of nickel and cobalt dissolution in the presence of acids and reducing …

X-ray photoelectron spectroscopy (XPS) has become a standard tool for the study of catalytic
materials over the last two decades, and with the increasing popularity of turnkey XPS …

A process for nickel recovery from a spent catalyst of definite composition has been
developed using the hydro-metallurgical route. The processing steps includes direct …

Authors' Note: This article reviews research published or presented in 1991 and 1992 that
we feel is likely to be of interest to those involved in hydrometallurgy and the aqueous …

In this study, column leaching experiments were carried out to investigate the extraction of Ni
and Co from low-grade limonitic laterites from Agios Ioannis mines in central Greece. Tests …

Smelter slag and sulphur dioxide are waste products of non‐ferrous pyrometallurgical
processes. Dissolution behaviour of Co, Cu, Fe, Ni and Zn from smelter slag in aqueous …

Leaching of Cu 2 O with aqueous SO 2 solution is significant, since during the dissolution
process, precipitation of copper as Chevreul's salt also takes place under appropriate …

Leaching of various oxide materials using sulfur dioxide is documented in this review.
Emphasis is given to the leaching of Fe (III), Mn (IV), Mn (III) oxides/hydroxides highlighting …

To assess the effectiveness of aqueous SO2 in extracting metal values from discarded
smelter slag, the dissolution behavior of Co, Ni, and Fe using SO2 (aq) and H2SO4 was …

Nichrome is extensively used in heating elements in industrial furnaces and metallurgical
industries. In this investigation, studies were carried out to determine the dissolution …
