Leaching behaviour and the solution consumption of uranium

Heap leaching is extensively applied to extract copper and gold from their respective ores. 2.2 Leach experiments The column leaching tests were conducted by a third party using subsamples from the calcrete ore type. In column A, after 142 days of leaching the uranium extraction was about 72.5% so leaching was sustained up to 190 days

Column Leaching for Simulating Heap and In situ Soil

For column experiments, air dried soil was first passed through a 1.25 cm sieve. All column leaching tests were conducted using a 3.8 cm diameter glass column, with a length of 61 cm. Solid reagents (metallic iron or ferrous sulfate powder) were mixed with the soil material before loaded into the column. The soil bed was about 50 cm in height.
