In order to alleviate the pressure on supply of lithium resources, this research proposes use binary/ternary collectors with high selectivity and collecting ability enhance flotation purification low-grade zinnwaldite ore. The binary collector is a mixture dodecylamine polyoxyethylene ether DL-2-octanol. A added first, followed by sodium oleate, known as ternary collector. Under acidic conditions, recovery Li2O in concentrate was increased 8.26% 13.70% collector, compared ether. enhanced...
Coal gasification fine slag is a kind of solid waste with low resource utilization rate. The complex embedding residual carbon and inorganic minerals (ash materials) the main reason restricting efficient separation or ash materials. Hydrophobic-hydrophilic (HHS) technology in which mineral particles different surface hydrophobicity values are enriched water phase oil under action mechanical stirring. on hydrophobic replaced by to form flocs, liquid phase, while hydrophilic dispersed into...
Abstract The accumulation of magnesite tailings (MT) poses challenges such as resource wastage, land occupation, dust generation, and environmental pollution, thereby jeopardizing both physical mental health. Urgent attention is required for the proper treatment this solid waste material. An in‐depth investigation into enhancing flotation processes MT essential. A comprehensive comprehension surface properties its principal gangue minerals assumes paramount importance in facilitating...
For the purpose of using coal gasification coarse slag, carbon/ash separation by flotation is necessary. In this work, kerosene and dodecylamine polyoxyethylene ether (AC1202) were combined to create a composite collector known as AK, which was used in experiments. The findings reveal that when dosage AK raised 14 kg/t, tailings ash reached high 83.76% combustible recovery increased 69.84% 81.42%, almost 28.62% higher than kerosene. characteristics various collectors, strength adsorption...
Low-rank bituminous coal has a low degree of metamorphism, high oxygen content, and poor hydrophobicity. When using conventional collector, it renders yield clean coal, making difficult to improve the quality via flotation. In this work, type diesel microemulsion (C1) was prepared primary alcohol ethoxylate (AEO-3), which adopted conduct The results demonstrated that compared with increased by 44.37%; content tailing ash 37.60%; combustible recovery rate improved 55.65%, respectively;...
Abstract With the growth of new energy industry, requirements for manganese have increased significantly. In this paper, method extraction from pyrolusite using ammonium sulfate roasting and water leaching was presented. At optimal process parameters: mass ratio (NH 4 ) 2 SO to 2:1, temperature 420°,C duration 120 min, efficiency Mn Fe 94.55% 54.38%, respectively. The mechanism analysis shows that MnO O 3 in were converted (SO , Fe(SO NH by with sulfate. Iron removed solution addition...
