Carrier-microencapsulation using Al-catecholate complex to suppress arsenopyrite oxidation: Evaluation of the coating stability under simulated weathering conditions

Autor: Seno Kensuke, Park Ilhwan, Tabelin Carlito, Magaribuchi Kagehiro, Ito Mayumi, Hiroyoshi Naoki

Publikováno v: MATEC Web of Conferences, Vol 268, p 06002 (2019)

Arsenopyrite (FeAsS) is the most common primary arsenic-sulfide mineral in nature, and its oxidation causes the release of toxic arsenic (As). To mitigate these problems, carrier-microencapsulation (CME), a technique that passivates sulfide minerals
