Copper Enrichment in Solid with Selective Reverse Leaching with Oxalic Acid
(Springer, 2020)As the first part of a novel process proposed for copper extraction, selective dissolution of iron from chalcopyrite in oxalic acid solutions with hydrogen peroxide was studied. Despite the fact that both iron and copper ... -
Pressure leaching of chalcopyrite with oxalic acid and hydrogen peroxide
(Elsevier, 2021)This study investigated the dissolution behavior of metals from chalcopyrite concentrate in a pressure reactor system in the presence of hydrogen peroxide by oxalic acid leaching. The fact that the compounds formed by ... -
Dissolution of Chalcopyrite in Presence of Chelating Agent and Hydrogen Peroxide
(Springer, 2021)Chelating agents (e.g., EDTA, titriplex III, etc.) are very important salts as they can take a complex form with metal ions. This study investigated usage of titriplex III in presence of hydrogen peroxide for metal extraction ... -
Environmental Prices and Energy Efficiency of Mandarin (Citrus Reticulata) Production: A Case Study of Hatay Province Turkey
(Parlar Scientific Publications, 2022)The main objective of this study was to determined environmental prices and energy efficiency for mandarin (Citrus reticulata) production in Hatay province of Turkey. This study was performed for 2019 production season in ... -
Preparation and characterization of activated carbons from Lemon Pulp for oxytetracycline removal
(Springer, 2023)This study aims to remove oxytetracycline (OTC) that harms the ecosystem, with activated carbon (LPAC) obtained from Lemon Pulp (LP). Characterization and properties of LPAC were analyzed by Brunauer-Emmett-Teller (BET), ... -
Investigation of atmospheric pressure leaching conditions and leaching kinetics in the obtaining of industrial copper (II) acetate solution from copper slags
(Springer, 2023)Although many technologies have been introduced to recover valuable metals from copper slags, their economic and environmental compatibilities were not satisfactory. The dissolution behaviors of metals from copper slag, ... -
Prevention of Wave Propagation via Circular Arrangement of Seismic Metamaterials Formed with Concrete Piles
(MDPI, 2023)It is known that the low frequencies of seismic surface waves have a destructive effect. The main purpose of seismic metamaterials is to protect structures from seismic waves at low frequencies, especially in a wide band. ... -
Catalytic pyrolysis of lignite with clay catalyst activated with spent pickling liquor
(Wiley, 2023)Spent pickling liquor (SPL) is an acidic waste with rich iron content from the stainless steel production industry. Reusability of SPL as a catalytic activity promoter in bentonite clay is crucial for the catalytic pyrolysis ... -
Dissolution behavior and kinetics of copper slag under oxidative conditions
(Elsevier, 2024)This study investigates the extraction and leaching kinetics of metals from slag, a by-product in pyrometallurgical copper production, under atmospheric leaching conditions in the presence of HCl-H2O2. The optimum leaching ... -
Leaching of copper slags by direct photooxidation mechanism using ultraviolet light
(Central South University of Technology, 2024)The dissolution behaviors of Cu and Fe from copper slags were investigated with photochemical reactions. Experiments were run intermittently with a quartz glass jacket in a glass reactor, by submerging ultraviolet (UV) ... -
Greener and Sustainable Production: Production of Industrial Zinc (II) Acetate Solution and Recovery of Some Metals (Zn, Pb, Ag) from Zinc Plant Residue by Ultrasound-Assisted Leaching
(Springer, 2024)Zinc plant residue (ZPR) contains significant amounts of valuable metal (Zn, Pb, Ag, etc.) compounds, as well as various heavy metals and harmful compounds that pollute the environment. Processing such residues allows for ... -
Sustainable Green Industry Work: Recovery of Copper Slag with Mill Scale Leaching Reactant Optimized by Response Surface Methodology (RSM)
(Springer, 2024)Copper slag (Cu:6.74%, Fe:36.45%) and mill scale (Fe:67.67) contain significant amounts of recoverable metals. This study consists of a two-stage experimental process. In the first stage, the mill scale was leached with ...
