    Nov 01, 2020 Nov 01, 2020 The leaching dynamics of Cu from the tailings concentrate seem to reach a dissolution plateau earlier than Co . For the bulk tailings, Co and Cu leaching dynamics showed similar trends data not shown. Thus, Cu in the tailings concentrate may be more refractory than Co for dissolution Schirmer et al., 2017. The large content of the silicate ...
