Abstract
This paper presents the results of a work that begun in the context of an ethnographic investigation about the modern mining at the region of A Gudiña (SE Orense province, Galicia, Spain). An interesting interview with a local resident (near Pentes) and former miner was made, who revealed a simple method for obtaining tin by direct reduction in a simple structure with subsequent casting of the metal into a mould made of a white turnip to obtain an ingot. The reduction process was executed and was documented, and can be considered as a very pertinent contribution in respect to the potentials of direct reduction of tin ores from the Barxa mining group, performed by local population for domestic consumption. Analytical studies were made on the ores and resulting materials to evaluate the purity grade of the tin produced, and evaluate possible relationships between the used minerals and the produced slags and metallic tin.
