“…The Co resource is relativlely rare on the earth, and the single Co reserve is only about 2% of the world, and it is difficult to mine and leach [3,4]. Skutterudite (CoAs 2 ) is one of important resources in the smelting of Co in China [5]. The main methods of skutterudite metallurgy are described by the follow reactions [6]:…”

“…Previous studies on the leaching of trace elements under different conditions have been conducted in many different study areas (Wagner and Hlatshwayo 2005;Sohlenius andÖ born 2004;Al-Masri et al 2004;Gaskova et al 2003;Quejido et al 2005;Gamage et al 2010). Studies on trace elements at the aquifer rock/water interface can provide very valuable information on the source and evolution process of groundwater.…”

Gaskova et al (2003) conducted laboratory-based experiments to study the leaching of As-containing tailings with different solutions and water/rock ratios and over different leaching times.…”

“…Τα «µεταδευτερογενή» υποδιαιρούνται σε «τριτογενή» και «τεταρτογενή». «Τριτογενή» ονοµάζονται τα ορυκτά που σχηµατίζονται µετά την αποµάκρυνση υλικού των απορριµµάτων από τους χώρους των τελµάτων για εργαστηριακή εξέταση, ενώ τα «τεταρτογενή» περιλαµβάνουν τα ορυκτά που σχηµατίζονται από επιφανειακή οξείδωση κατά την αποθήκευση ξηρών δειγµάτων(BIGHAM, 1994).O χαλαζίας αποτελεί το κύριο ορυκτολογικό συστατικό των αποθέσεων των απορριµµάτων των κοιτασµάτων του τύπου αυτού και πολλές φορές ξεπερνάει το 40% του συνόλου(GASKOVA et al, 2003). Σε µικρότερα ποσοστά εντοπίζονται πρωτογενή θειούχα ορυκτά, οξείδια και υδροξείδια του Fe, θειικά και αργιλικά ορυκτά…”
