ChemSusChem, Volume 18, Issue 6, March 15, 2025.Lithium carbonate (Li2CO3) obtained from the black mass of recycled lithium batteries is dissolved in water under controlled conditions to remove lithium fluoride (LiF), which is present at a concentration of 3.08 % by weight. The dissolution is carried out at temperatures below 10 °C, and it has been demonstrated that lower temperatures result in ...

Short history of teaching mineralogy at the Eötvös Loránd University, Budapest [PDF]
, 2004 We intend to overview the 230-year history of organised teaching of mineralogy at the Eötvös Loránd University. The University was founded in 1635. Students could learn certain elements of mineralogy already in the early period of the University within ...

MINERAL TRANSFORMATIONS OF HYALOCLASTITE DURING LITHOGENESIS IN MASSIVE SULFIDE BEARING REGIONS OF URALS [PDF]
Минералогия, 2015 The features of the submarine transformations from primary hyaloclastites to oxide-ferruginous rocks of the Urals massive sulfide deposits are identified. These processes are accompanied by formation of smectite and Si-Fe phases transformed into chlorite-

Trial calculation of relating the equilibrium state of minerals to the descriptive mineralogy [PDF]
, 1997 Statistical calculation have been carried out on the volumes of the asymmetric unit of minerals. This treatment is related to the origin of the symmetry and periodicity of the crystals, and to the equilibrium conditions of these crystals.

Critical expansion points: Mechanical signs of surrounding rock instability
Deep Underground Science and Engineering, EarlyView.This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...
