The identification of surface sulfide and polysulfide species based on the curve fitting of S2p
photoelectron spectra and, for the first time, of X-ray excited S KLL Auger spectra has been …

Prebiotic organic synthesis catalyzed by Earth-abundant metal sulfides is a key process for
understanding the evolution of biochemistry from inorganic molecules, yet the catalytic …

The mechanism of the initial steps of pyrite (100) surface oxidation was investigated in detail
by means of density functional theory/plane-wave calculations. Pyrite oxidation is related to …

In order to unravel the oxidation mechanism (s) of chalcopyrite (CuFeS 2) surfaces, the
surface anisotropy of CuFeS 2 was investigated under both dry and aqueous atmospheres …

浮选是硫化铜矿除砷的主要工艺, 毒砂和硫化铜矿具有相似的表面化学性质和可浮性,

In order to better understand the floatability of molybdenite (MoS 2), the anisotropic
properties of MoS 2 faces and edges were investigated, followed by the adsorption of H 2 O …

Separating chalcopyrite from arsenopyrite using flotation has been a big challenge due to
their similar floatability. However, this challenging condition may be partially solved by …

Arsenopyrite is a common mineral that is abundant in nonferrous metal tailings. Study of the
atomic configuration, chemical state, and morphology of the oxidation products of the …

A highly selective depressant is of critical importance for efficient Cu-As separation. Herein,
the depression mechanism of peracetic acid (PAA) with respect to arsenopyrite is …

During the flotation of chalcopyrite from arsenopyrite, the addition of lime (with CaOH+ as
the active component) can affect the subsequent high-gradient magnetic separation (HGMS) …
