The leaching of uranium from betafite [PDF]
, 2015 Betafite is a uranium–titanium–tantalum–niobium complex oxide mineral generally described as (Ca,U)2 (Ti,Nb,Ta)2 O6 (OH). Significantly lower uranium extractions have been observed when betafite containing ores has been treated via conventional process ...

Study of rational solution parameters during in-situ uranium leaching
Mining of Mineral DepositsPurpose. The research aims to study and optimize the in-situ leaching (ISL) process for uranium mining using surface-active substances (surfactants) to improve the efficiency of uranium extraction from low-permeability ores. Methods. As part of the research, samples of low-permeability ores are taken and previously analyzed for porosity and ...
