The flotation reagents (0.2 lb/ton fuel oil and 0. 1 lb/ton MIBC frother) were added and an additional 5 minutes of conditioning allowed. Flotation of molybdenite then proceeded for 3 minutes. Both the concentrates and tailings were saved, dried, and weighed to determine the copper-depression percentages.

The catalytic influence of Sulfolobus metallicus in the bioleaching of pure chalcopyrite at 70° C and pH 1.5 was studied in shake flask experiments. In order to evaluate separately the influence of planktonic and attached cells on the catalytic process, in some experiments the microorganisms were prevented from reaching chalcopyrite …

Chalcopyrite and pyrite show recovery of over 90% when working with SBX and MIBC at pH 4–10. An increase in pH to 11.5 allowed lowering the pyrite recovery to 63%. However, when using PCA, pyrite flotation was significantly reduced at pH 4–8, while chalcopyrite was slightly affected, with recoveries over 90%.

chalcopyrite, the most common copper mineral, a copper and iron sulfide, and a very important copper ore. It typically occurs in ore veins deposited at medium and high temperatures, as in Río Tinto, Spain; Ani, Japan; Butte, Mont.; and Joplin, Mo. Chalcopyrite (Cu 2 Fe 2 S 4) is a member of a group of sulfide minerals that crystallize …

The absence of spatial inversion symmetry at both local (point group ) and global (crystal class ) levels greatly influences the electronic properties of chalcopyrite (CuFeS 2).The predicted dichroic signals (natural circular, non-reciprocal and magneto-chiral) and resonant, parity-odd Bragg diffraction patterns at space-group forbidden …

This paper reviews the properties of methanesulfonic acid (MSA) and its potential for use in hydrometallurgy. Although MSA is much less known than sulfuric, hydrochloric or nitric acid, it has several appealing properties that makes it very attractive for the development of new circular flowsheets in hydrometallurgy. Unlike other organic …

Chalcopyrite is the most refractory copper mineral. Harsh conditions (highly acidic solutions, high pressure and temperature, or thermal and chemical pretreatments) are required. Direct electrochemical leaching attempts to improve the limited chemical dissolution, for example, by using chalcopyrite slurry as a massive electrode (which has ...
