Testing of 17-different leaching agents for the recovery of zinc from a carbonate-type Pb-Zn ore flotation tailing
(PERGAMON-ELSEVIER SCIENCE LTDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2021)
The recovery of zinc from a flotation tailing using 17-different leaching agents, including inorganic and organic acids, alkaline solutions and chelating agents, was investigated. The effects of the lixiviant type, acid ...
Production of precipitated calcium carbonate particles from gypsum waste using venturi tubes as a carbonation zone
(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 01.01.2019)
In this study, we investigated the production of precipitated calcium carbonate (PCC) particles from desulfurization gypsum (DG) waste using a new experimental apparatus that is divided into two main parts: carbonation and ...
Pb-Zn recovery from a malic leach solution of a carbonate type ore flotation tailing by precipitation and solvent extraction
(ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021)
The recovery of zinc and lead from a malic leach solution of a carbonate type ore flotation tailing by precipitation with sulfuric acid followed by solvent extraction using di(2-ethylhexyl)phosphoric acid (D2EHPA) as ...
Production of mixed rare earth oxide powder from a thorium containing complex Bastnasite ore
(ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021)
The production of mixed rare earth oxide powder from a thorium containing bastnasite ore by sulfuric acid bake water leaching followed by precipitation with oxalic acid and thermal decomposition of the oxalates was ...
Recovery of Vanadium and Nickel from a High CaCO3 Containing Petroleum Coke Ash by Roasting and Acidic Leaching
(SPRINGER, 2023)
In this study, it was aimed to extract vanadium (V) and nickel (Ni) from a petroleum coke ash (PCA) using a roasting process
without additives, followed by leaching with sulfuric acid (H2SO4). The experiments were designed ...
Recovery of Lithium from Spent Coin-Type Lithium Manganese Dioxide CR Cells by Acidic Leaching in the Presence of Potassium Permanganate as Oxidant
(SPRINGER LINK, 2023)
The selective leaching of lithium from spent coin-type lithium manganese dioxide CR cells by oxidative leaching and precipitation of Li2CO3 from Libearing leach solution has been experimentally and theoretically investigated. ...
A distinctive determination of circular nozzles in downcomer for column flotation
(Taylor and Francis Ltd., 2023)
This study aims to recover clean coal from valuable hard coal tailings (HCT), which have been used as solid fuels in a thermal power plant, through convenient conditions. The effective diameters of circular nozzles on the ...
Concentration study of a specularite ore via shaking table, reverse flotation, and microwave-assisted magnetic separation
(Taylor and Francis Ltd., 2023)
Despite the difficulties in pelletizing specularite-type refractory iron ores, the utilization of these resources is indispensable for the steel industry due to the increasing need for iron. This study investigated Fe ...
Separation of Mn and Fe from a Manganiferous Iron Ore Using Horse Dung as Reductant: A Zero Waste Approach
(SPRINGER, 2022)
The separation of manganese and iron from a manganiferous iron ore using horse dung (biomass) as reductant was investigated in a sulfuric acid solution, and 99.80% Mn and 17.76% Fe were extracted into the solution under ...
