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. ...
