Mining wastes and calcines from two abandoned mining areas (Valle del Azogue and Bayarque in Almería) have been characterized. The mines in Almadén (Spain), Monte Amiata (Italy), and Idrija (now Slovenia) dominated mercury production from the opening of the mine in Almadén 2500 years ago, until new deposits were found at the end of the 19th century.

Heritage of Mercury Almadén and Idrija (Slovenia/Spain): The property includes the mining sites of Almadén, where mercury (quicksilver) has been extracted since Antiquity, and Idrija, where mercury was first found in 1490 A.D. Mercury exposure and mechanism of response in large game using the Almadén mercury mining area (Spain) as a case study. Jean Remy Davée Guimaraes, Oscar Betancourt, Marcio Rodrigues Miranda, Ramiro Barriga, Edwin Cueva, Sebastián Betancourt. Humans have been mining mercury ore from the deep earth (the “lithosphere”) since at least the Roman times. Mercury is of particular concern amongst global environmental pollutants, with abundant contaminated sites worldwide, many of which are associated with mining activities. Later, during the California gold rush, variations of the patio process were used to extract gold. Almadén Mine, Almadén, Almadén mining district, Ciudad Real, Castile-La Mancha, Spain : A mercury mine started before 1850. Introduction. Mercury is very dangerous in non metallic form though.

So it all is quite consistent. Supported by large mercury mines in Almaden, Spain, and Huancavelica, Peru, the patio process was critical to the rapid expansion of Spanish silver production during the 17th and 18th centuries. The Almaden Mercury Mine is in Ciudad Real, Spain. Spain was the region with the richest mercury ores since antiquity (AFAIR).

Introduction Asturias, in northwestern Spain, is a region with a long mining tradition (coal mining has been the economical motor of the region for centuries). In the United States, mercury mining has also stopped, although small quantities of mercury are recovered as part of the gold refining process to avoid environmental contamination. Asturias (Northwest of Spain) can be considered an Hg metallogenic province with abundant epithermal-type deposits, whose paragenetic sequences include also As-rich minerals. The widespread use of mercury as an amalgamation agent for the recovery of gold and silver in small-scale alluvial mining has been a serious local environmental problem for some centuries in parts of Latin America and elsewhere (Nriagu, 1993).

Spain has one of Europe’s most diverse mining industries, which produces most of the industrial minerals. Asturias (Northwest of Spain) can be considered an Hg metallogenic province with abundant epithermal-type deposits, whose paragenetic sequences include also As-rich minerals. Major world producers of mercury are Algeria, Kyrgyzstan, Spain and China. Despite low demand, low prices and the alternative sources available, mercury is still mined in a number of countries such as Spain, China, Kyrgyzstan and Algeria.
