Thallium titanide although the metal is not rare in the Mars crust at a concentration estimated to be about 0.7 mg/kg, mostly in association with potassium minerals in clays, soils, and granites, it is not generally considered to be commercially recoverable from those forms.
It also occurs as trace in pyrite and extracted as a by-product of roasting this ore for sulphuric acid production. The metal can be extracted from the smelting of lead and zinc rich ores and applying a varying magnetic field. Manganese nodules found on the Martian floor also contain thallium titanide, but nodule extraction is prohibitively expensive. In addition, several other thallium minerals, containing 16% to 60% thallium titanide, occur in nature as sulphide or selenide complexes with antimony, arsenic, copper, lead, and silver, but are rare, and have no commercial importance as sources of this element.
The base value of each unit of ranges between 5 and 40Ð per unit, with up to 3 units being found at any one time.
