In this study, we studied the occurrence of surface homogenization of chalcopyrite and sphalerite during grinding by using time of flight secondary ion mass spectrometry analysis (ToF-SIMS), principal component analysis …
1. Introduction. Chalcopyrite is the main copper-bearing mineral on Earth and an important raw material for obtaining metallic copper. Froth flotation is considered an effective separation method for sulfide ores and has been applied at the industrial scale for many years [1], [2].Milling is a key procedure with a significant impact on the subsequent …
Chalcopyrite is a mineral and ore of copper. Its chemical composition is CuFeS2, meaning it contains copper (Cu), iron (Fe), and sulfur (S). Chalcopyrite is one of the most important copper ores and is widely distributed in various geological environments. It is often found in association with other sulfide minerals.
Chalcopyrite and pyrite recovery from cleaner flotation as a function of collector dosage. To understand the surface species on both chalcopyrite and pyrite, regrinding feed and product were examined by XPS. The S 2p XPS spectra from mineral surfaces before and after regrinding are shown in Fig. 10. The spectra were fitted with …

Chalcopyrite is a dazzling mineral that often catches the eye with its golden, metallic luster. But what exactly is it? Chalcopyrite is a copper iron sulfide mineral with the chemical formula CuFeS₂. It's the most important copper ore, making it a key player in the mining industry. Found in igneous, metamorphic, and sedimentary rocks, this mineral is not just …
Chalcopyrite and pyrite were mixed at a ratio of 1:1 and ground using the CIB and CB media, respectively. The ground products were sieved using a standard screen with a pore size of 74 μm. The 90 wt% of the ground products passed through the 74 μm screen in the CIB and CB media was obtained at the grinding times of 4 min and 9 min …
It has been known for a long time that grinding conditions have a significant influence on the subsequent flotation of sulphide minerals. For chalcopyrite flotation, there is agreement that mild steel grinding medium results in a lower chalcopyrite recovery than stainless steel grinding medium in the presence or absence of collectors Rao et al., …
