Separation of molybdenite from chalcopyrite with thiolactic acid depressant: Flotation behavior and mechanism

Transactions of Nonferrous Metals Society of China, Год журнала: 2023, Номер 33(10), С. 3157 - 3167

Опубликована: Окт. 1, 2023

The separation of molybdenite and chalcopyrite is a major challenge because their similar floatability. It essential to discover depressant for selectively inhibiting in profitable sustainable way. A novel depressant, thiolactic acid (TLA), was proposed. flotation behaviors were studied through micro-flotation artificial mixed minerals flotation. Micro-flotation experiments indicated that could significantly suppress recovery from 81% 9.7%, along with always more than 71%. Artificial showed distinct behavior between an optimal Gaudin's selectivity index 12.9. reactivity mechanism TLA on surfaces determined by FT-IR, XPS, AFM possible adsorption model presented. results revealed —SH —COOH groups preferentially occupied the active copper site surface, subsequent sodium n-butyl xanthate chemisorption.

Constructing a Cr-Substituted Co-Free Li-Rich Ternary Cathode with a Spinel-Layered Biphase Interface

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(27), С. 34880 - 34891

Опубликована: Июль 1, 2024

Lithium-rich manganese-based layered oxides (LRMOs) have recently attracted enormous attention on account of their remarkably big capacity and high working voltage. However, some inevitable inherent drawbacks impede wide-scale commercial application. Herein, a kind Cr-containing Co-free LRMO with topical spinel phase (Li1.2Mn0.54Ni0.13Cr0.13O2) has been put forward. It found that the valence Cr6+ can reduce Li+ ion content induce formation local by combining more ions, which is beneficial to eliminate boundary between bulk material, thus dramatically avoiding separation during cycling process. In addition, introduction Cr also expand layer spacing construct stronger Cr–O bond compared Mn–O, enables combine transition metal (TM) slab prevent migration TM ions transformation phase. Simultaneously, synergistic effect successfully constructed spinel-layered biphase interface strong effectively escape lattice oxygen initial activation process Li2MnO3 provide fast diffusion path for transmission, further reinforcing configurable stability. Besides, Cr-LRMO presents an ultrahigh first discharge specific 310 mAh g–1, Coulombic efficiency as 92.09%, good stability (a retention 94.70% after 100 cycles at 1C), small voltage decay (3.655 mV per cycle), well rate (up 165.88 g–1 5C).
