Historical roasting of thallium- and arsenic-bearing pyrite: Current Tl pollution in the Riotinto mine area

Abstract: Samples of an open-air pyrite roasting heap from the 19 th century in the Riotinto mine area (SW Spain) and surrounding sediments and soil along a seasonal surface runoff channel were analyzed to study thallium (Tl) phase transformations during historical roasting of Tl-bearing arsenian pyrite, secondary weathering processes, Tl dispersion and current environmental pollution. Results from Electron Probe Microanalyses (EPMA) indicate an even distribution of Tl in pyrite grains of an ore sample (22 mg kg-1 total… Show more

“…In 2014, severe Tl contamination in drinking water (15 mg/L in the spring water) was discovered in northern Tuscany, Italy, resulting in a severe Tl accumulation in urine and hair of local residents (Campanella et al, 2016;Biagioni et al, 2017). China has abundant Tl-bearing mineral resources, and the mining and smelting activities have released large amounts of Tl into aquatic environments (Liu et al, 2010;Xu et al, 2019;Liu et al, 2020). Several rivers in South China such as the North River in Guangdong province, the Hejiang River in Guangxi province, and Xiannv Lake in Jiangxi province were contaminated by the discharge of wastewater containing high Tl.…”

“…In recent years, with the improvement of China's industrial level, the development of the mining industry has accelerated. A large amount of solid waste and wastewater from mining has become the main cause of water pollution around the mine [1][2][3]. The main components of these solid wastes and wastewater are heavy metals.…”

“…Thallium is an important element used in superconductive materials (Murakami et al, 1996), medicine (Bauman et al, 1993;Kassis et al, 1983), electronics (Horn et al, 1983;Kaufman et al, 1970), chemical industries (Červeny et al, 1986;Gaikwad, 2011), and radiation dosimetry (Hitomi et al, 1999;Rahman et al, 1987) and it has accordingly been analyzed in various environments (Jacobson et al, 2005;Peter and Viraraghavan, 2005;Xiao et al, 2003;Zhou et al, 2008). Anthropogenic Tl pollution of soils and waters has been related to cement production, coal mining and burning, as well as metal sulfide mining and ore smelting (Belzile and Chen, 2017;Vanĕk et al, 2013;Lukaszewski et al, 2018;Liu, et al, 2018;Ghezzi et al, 2019;López-Arce et al, 2019;Cruz-Hernández et al, 2018).…”
