2021-4-15  The leaching of thallium from ore processing operations is the major source of elevated thallium concentrations in water. It is known to stay in the air, water, and soil for a long period of time after it is released. Thallium (TI) is a rare heavy metal in drinking water, but its extreme toxicity makes its removal crucial to consumer health.

2014-8-1  At the same time, total thallium in processing waste is significantly lower (0.71 μg g − 1) than in crude ore. The major fraction obtained during sequential extraction is oxidizable thallium. Crude ore contains approximately 50% oxidizable thallium, and all other fractions of the flotation process contain approximately 40–70%.
