Most investigators regard CuFeS 2 as having the formal oxidation states of Cu+ Fe 3+(S 2−)
2. However, the spectroscopic characterisation of chalcopyrite is clearly influenced by the …

Chalcopyrite (CuFeS 2) is the most abundant copper-containing resource in the earth and is
also widely distributed in solid wastes and secondary resources. Biohydrometallurgy …

The separation of chalcopyrite from pyrite is usually carried out under high alkaline
conditions. However, the separation mechanism of chalcopyrite from pyrite under high …

The need to process low-grade and/or complex chalcopyrite-containing ores that cannot be
concentrated is the main driver for the development of hydrometallurgical processes. The …

We employed computational density functional theory (DFT) and microflotation tests
complemented by analysis of electronic properties and X-ray photoelectron spectroscopy …

Chalcopyrite is a prime, plentiful and widely distributed form of copper-bearing mineral.
Compared with the traditional pyrometallurgy process, biohydrometallurgy has …

In this work, density functional theory (DFT) calculation, X-ray photoelectron spectroscopy
(XPS) and electrochemistry analysis were carried out to investigate the dissolution process …

The selective separation of molybdenite from chalcopyrite is difficult because of their similar
floatability in the presence of a collector. In this study, rhodanine-3-acetic acid (3-Rd) was …

Recently, increasing attention has been paid to the activated peroxymonocarbonate (APMC)
process, because it is envisioned to be engineered for the chemical oxidation remediation of …

Chalcopyrite (CuFeS 2) is one of the main copper minerals, and is always found associated
with pyrite (FeS 2). To obtain a satisfactory Cu concentration, the undesirable pyrite …
