Microscopic seepage mechanism during in-situ leaching of weathered crust elution-deposited rare earth ores
摘要：In order to reveal the microscopic seepage mechanism during in-situ leaching of weathered crust elution-deposited rare earth ores,microscopic pore structure characteristics(pore scale,pore distribution and pore form)of the upper,middle and bottom samples in four different kinds of the rare earth ores after leaching were quantitatively analyzed using both scanning electron microscopy and image processing technology.Relationship between the microscopic structure characteristics and the permeability coefficient was discussed as well.
