At creation of technology of Cobalt-bearing ferromanganese crusts (Pacific ocean) processing are received the firm waste products containing Thallium. By analytical electronic microscopy was determined that thallium presence mainly as an independent mineral phases, but also can be an isomorphic impurity in the rock-bearing minerals.
The form of thallium presence and its distribution in the processing products of crusts are very important for ecological safety maintenance of this kind of raw material industrial processing.
