A selective recovery of zinc and manganese from the spent primary battery black mass as zinc hydroxide and manganese carbonate

Open Engineering
The major challenge in zinc–carbon battery recycling lies in achieving selective separation of zinc and manganese while producing high-purity materials suitable for advanced applications. This study aims to develop a selective hydrometallurgical approach

Image5_Utilization of amino acid for selective leaching of critical metals from spent hydrodesulfurization catalyst.tif

, 2022
While spent catalysts can cause serious environmental pollution, they can be considered an essential secondary metal source due to their high critical metal grades.

Selective reductive leaching of an oxidised cobalt hydroxide containing residue

, 2013
Nickel was selectively leached from an industrial nickel-cobalt Mixed Hydroxide Precipitate (MHP) under mildly acidic, strongly oxidizing conditions. The resulting cobalt rich residues contained 14-21 wt.% Ni, 3-7 wt.% Co and 3-9 wt.% Mn.

A Review of the Application of Oxalic Acid in Hydrometallurgical Processes

Separations
Conventional hydrometallurgical processes typically employ inorganic acids as leaching agents; however, these processes are frequently associated with significant environmental pollution and suffer from poor metal selectivity.

Selective Recovery of Manganese from Anode Sludge Residue by Reductive Leaching [PDF]

, 2020
Manganese-containing anode sludge is a common side-product in the electrowinning of zinc. The anode sludge consists mainly of oxidized manganese, but also lesser amounts of lead, calcium, and other minor metals. The impurities present in the anode sludge

Phase selective leaches for use in exploration geochemistry

, 1996
This paper describes the development and evaluation of a sequential extraction scheme for application to soils, tills, and surficial sediments to elucidate the form(s) in which an element is held and hence to provide information as to its genesis. The operationally defined phases selected for extraction have been assigned the following categories ...

Application of alternative lixiviants for secondary heap leaching of gold [PDF]

, 2000
Some preliminary results on the secondary leaching of previously heap leached gold ore are presented. Alternative lixiviants for gold comprising chlorine, thiourea and thiosulphate were compared with cyanide using bottle roll tests.
