Mineral chemistry of In-bearing minerals in the Santa Fe mining district, Bolivia

ABSTRACT The Santa Fe mining district is located in the Central Andean tin belt of Bolivia and contains several Sn-Zn-Pb-Ag deposits. From the economic point of view, the most important deposits of the district are Japo, Santa Fe and Morococala. Beyond the traditional metal commodities, the Central...
