Abstract

From the beginning of the twentieth century, the use of differential flotation gave rise to profound changes in mining as it enabled a wider range of minerals to be processed and low-grade and complex ores to be extracted profitably. This paper analyses how this technology spread throughout Spain, especially in the Sierra de Cartagena-La Unión, where it was heavily used. The question remains, however, regarding the long delay in the incorporation of such a profitable system in Spain. We will examine the reasons for this and highlight institutional elements as the main hurdle in adopting new concentration techniques. We will also study the huge impact that large-scale flotation had on this particular mining area, where it caused one of the greatest ecological disasters ever attributed to mining
