Leaching of complex gold ore using a cyanide-glycine solution

Kianoush Barani et al.

Summary: In this research, the leaching of complex gold ore was studied using cyanide and glycine. The increase in cyanide concentration led to an increase in gold dissolution, and the addition of glycine significantly enhanced the gold dissolution. The solid content and H2O2 concentration also influenced gold dissolution.

Extraction of precious metals from waste printed circuit boards using cyanide-free alkaline glycine solution in the presence of an oxidant

Huan Li et al.

Summary: This study provides a greener approach to extract precious metals from waste printed circuit boards using alkaline glycine solution in the presence of an oxidant. Two oxidants, potassium permanganate and potassium ferricyanide, were compared in alkaline media. The results showed that decreasing particle size and increasing oxidant concentration significantly enhanced gold extraction.

Extraction of Gold and Copper from Flotation Tailings Using Glycine-Ammonia Solutions in the Presence of Permanganate

Huan Li et al.

Summary: This study presents a cyanide-free leaching method, glycine-ammonia leaching in the presence of permanganate, for treating low-grade and copper-bearing gold tailings. The addition of glycine, ammonia, and permanganate significantly enhanced gold and copper extractions. The solids content had no significant effect on copper extraction, while gold leaching kinetics was slightly better at lower solids content.

Selective leaching of zinc from carbonate source using glycine as an ecofriendly lixiviant

Hamid Khodaei et al.

Summary: A selective leaching process of zinc from a low-grade carbonate source using glycine as a green lixiviant is proposed in this study. Response surface methodology and statistical modeling were employed to optimize the process variables and quantify their significance and interactions. Under the optimal conditions of glycine concentration = 1.5 M, pH = 9.5, and temperature = 70 ?, more than 90% of zinc was leached with negligible leaching percentages of main impurities.

Hydrometallurgical leaching and recovery of cobalt from lithium ion battery

Manivannan Sethurajan et al.

Summary: The main objective of this study was to investigate the leaching ability of glycine on cobalt from lithium-ion batteries (LiBs). The study optimized the process parameters such as temperature, pulp density, and concentration of glycine to maximize the leaching efficiency of cobalt. Response surface methodology (RSM) was employed to determine the experimental conditions and interactions between different factors. The results showed that cobalt leaching efficiency could be improved under specific conditions of temperature, pulp density, and glycine concentration.

Leaching of a polymetal gold ore and reducing cyanide consumption using cyanide-glycine solutions

Kianoush Barani et al.

Summary: The study investigated the leaching of a polymetal gold ore using a synergistic lixiviant mixture of cyanide and glycine. Increasing cyanide concentration from 500 to 1500 ppm resulted in a higher gold dissolution rate. However, using 0.5-1 M/L glycine in 500 ppm cyanide can achieve 90% gold dissolution with increased copper dissolution.。Reducing cyanide consumption by approximately 80% was achieved at the optimal approach, but increasing glycine concentration also led to higher dissolution of other metals like Pb, Zn, Fe, Ag, and Cu.

Cyclic voltammetry and potentiodynamic polarization studies of chalcopyrite concentrate in glycine medium

Maryam Khezri et al.

Summary: The mechanism and kinetics of glycine leaching reactions for chalcopyrite were investigated using cyclic voltammetry and potentiodynamic polarization analyses. Factors such as pH, temperature, and glycine concentration were found to affect corrosion current density, corrosion potential, and cyclic voltammograms. Increasing glycine concentration led to higher oxidation peak current density, while elevated temperatures initially increased measured current densities before causing a decrease. pH changes also had a significant impact on current density behavior.
