Effects of radiation on the leach rates of vitrified radioactive waste

Journal of Nuclear Materials, 1982
AbstractThis report reviews the possible effects of both radiation damage to the glass and of radiolysis of the leachant on the leaching behaviour of vitrified radioactive waste. It has been stimulated particularly by recent papers, which have suggested that the leach rates of glasses will be enhanced by large factors after a ‘critical’ dose of ...

Heap leaching: a gas diffusion rate-limited model.

, 1977
The consequences are examined of assuming that the oxidation rate of pyrites in an overburden dump is determined by the rate at which the oxygen required can be supplied from the top surface of the heap by diffusion through the pore space of the heap. It

KINETIC MODEL FOR IDENTIFYING THE RATE CONTROLLING STEP OF THE ALUMINUM LEACHING FROM PEAT CLAY

, 2018
The aluminum (Al) leaching kinetics from peat clay was investigated using various acid concentrations 1 M to 6 M, particle sizes +70-120 mesh to +200-325 mesh and temperatures 30 °C to 90 °C. They all have significant effects on aluminum leaching process.
