Coupling fine particle and bedload transport in gravel-bedded streams [PDF]

, 2015
Fine sediments or particles are important determinants of water quality and ecosystem health. Various contaminants such as nutrients and heavy metals are transported by fine particles and the deposition of fine particles at the surface of stream beds ...

Effect of Leaching on Particle Migration and Pore Structure of Ionic Rare Earth Ores with Different Fine Particle Contents

Metals
In in situ leaching, fine particles can be stripped and transported with the leach solution, significantly altering the particle size distribution and pore structure of each layer of the rare earth ore body.
