shown in Table 1. These early testwork campaigns showed that the magnetite in the EHM comminution circuit is preferentially milled due to the hydraulic rather than size-based nature of the magnetite in the primary classification circuit of the copper concentrator (Zhu et al 2004) . The consequence is

Origin of High-Efficiency Photoelectrochemical Water ...

Jan 31, 2019· Introduction. Hematite (α-Fe 2 O 3) thin films have been actively investigated for photoelectrochemical (PEC) water splitting because of their narrow band gap of approximately 1.9–2.2 eV, their sufficiently deep valence band position for water oxidation, and high relative existence of hematite in the earth's crust.It has been reported to possess a maximum theoretical photocurrent of …
