"Tin is a rare element; among the base metals it is one of the rarest. Although it was one of the first metals used by man and has been used since prehistoric time, the ore-dressing and metallurgical methods of tin are inefficient and very wasteful.
The only tin deposits of importance in the Americas are located in Bolivia, South America, and it is in Bolivia that the problems of tin metallurgy are greatest. More than 50% of the tin that is mined in Bolivia is lost in the tailing dumps of the beneficiation plants. In a country where the export of tin represents 50 to 60% of the total income from foreign exchange, this loss is of considerable importance to the national economy. The waste of human labor under the severe conditions imposed by the high altitudes in which the mines are located is a supplementary factor of great significance.
For these reasons it was decided to investigate the possibilities of studying different methods of approach to the metallurgy of tin with the hope of eventually developing more efficient processes of recovering the tin content from its ores"--Introduction, page 1.
