The past decade has seen significant interest in non-conventional lixiviants, particularly the
growing interest in organic acids and amino acids. Of the amino acids, glycine has much …

Iron (Fe) is an essential transition metal. Based on its redox-active nature under biological
conditions, various Fe compounds serve as cofactors in redox enzymes. In plants, the …

Zinc ferrite (ZnFe2O4), one of the major forms of zinc in electric arc furnace dust and zinc
leaching residue, is very difficult to chemically dissolve in either acidic or alkaline solutions …

Currently, the generation of electrical and electronic wastes is growing fast, thereby the
reduction of the environmental impacts generated by its inadequate disposal is an ongoing …

Currently, the use of called “green solvents” is a challenge that must be assumed by the
industry, since they contribute to a friendly process and where its use has been extended …

Oxide copper minerals are commonly extracted via acidic leaching, using acids such as
H2SO4, HCl, or HNO3. These strong acids are the most widely used because of their high …

The production of photovoltaic modules is increasing to reduce greenhouse gas emissions.
However, this results in a significant amount of waste at the end of their lifespan. Therefore …

Recent studies of metal leaching using monosodium glutamate have shown promising
results of this being an alternative to conventional leaching reagents. However, limited …

This study aimed to recover copper and gold from a waste printed circuit board (WPCB)
using monosodium glutamate (MSG) supplemented with a clean oxidizer (s) under 30° C …

Sulfating roasting tests were conducted with different agents to investigate lithium recovery
from spent lithium-ion manganese oxide (LMO) batteries. In this study, CaSO4 and CaCO3 …
