Selective Recovery of Metallic Zinc from Zinc Leaching Residue by Calcification Roasting and Acid Leaching

Materials
It is essential to recycle zinc leaching residue (ZLR) generated by the conventional zinc hydrometallurgy process, as it is a hazardous and potentially valuable industrial waste. A combined calcification roasting–acid leaching process was developed to selectively separate and recover zinc from ZLR.

Selective Leaching of LiFePO4 by H2SO4 in the Presence of NaClO3

Revista de Chimie, 2020
Herein, problems commonly observed for the wet leaching of waste LiFePO4 cathode materials, namely extensive Fe leaching and impurity removal, are mitigated through the use of NaClO3, and the effects of leaching parameters on Fe, P, Li, and Al leaching efficiencies are probed. As a result, optimal leaching conditions are determined as temperature = 90

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 ...

Nitrogen leaching from effluent irrigated pasture [PDF]

, 2011
The surface waters of the Taupo region are of high quality and are sensitive to inputs of nitrogen. To reduce the amount of nitrogen discharged to surface water, the Taupo District Council (TDC) has employed a land treatment scheme (LTS), where treated ...
