The performance of conventional bentonite-based drilling fluids is severely compromised in high-salinity and high-hardness brines, creating a need for salt-tolerant viscosifiers. This work provides a comprehensive performance evaluation of an activat...
The extraction of rare earth elements is becoming increasingly essential due to their many applications in current and emerging advanced material technologies. However, in many rare earth deposits, rare earth minerals are associated with radionuclide...
Tennantite (Cu12As4S13) and enargite (Cu3AsS4) are two important minerals that simultaneously contain copper and arsenic. Detailed studies of their structure and properties are crucial for understanding their oxidation, flotation, and leaching. This...
Magmatic zircon trace element compositions and their variation trends provide valuable insights into the nature and evolutionary processes of magmatic rocks. The Himalayan orogen contains widespread leucogranites. Despite extensive studies on these g...
We present an integrated methodology for three-dimensional inversion of large-scale airborne electromagnetic (AEM) and magnetic survey data that simultaneously recovers electrical conductivity, chargeability, and both induced and remanent magnetizati...
The synthesis, crystal structure, phase transformations, and thermal expansion of (Y1–xEux)2(SO4)3*8H2O (where x = 0, 0.17, 0.33, 0.50, 0.66, 0.83, and 1) are presented. (Y1–xEux)2(SO4)3*8H2O solid solutions were synthesized via crystalli...
Lava tubes on Earth provide unique hydrogeological niches for life to proliferate. Orbital observations of the Martian surface indicate the presence of lava tubes, which could hold the potential for extant life or the preservation of past life within...
The Muji carbonic springs on the northeastern margin of the Pamir Plateau provide a natural window into tectonically controlled CO2 degassing within a continental collision zone. Through mineralogical and geochemical analyses, this study constrains t...
Precise segmentation of flotation froths is a critical bottleneck to achieving intelligent perception and optimal control of process operations. Traditional convolutional neural networks (CNNs) are inherently limited by local receptive fields, making...
To address the issues of high cost and poor low-temperature adaptability in cement-based backfill materials, this study developed a high-volume fly ash-based solid waste cementitious backfill material (FAPB) along with a specialized low-temperature a...
