Abstract. The objective of this project is to conduct extensive studies on the surface reactivity of pyrite by using electrochemical, surface analysis, potentiometric and calorimetric titration, and surface hydrophobicity characterization techniques and to correlate the alteration of the coal-pyrite surface with the efficiency of pyrite rejection in coal flotation.
The effect of particle characteristics and hydrodynamic conditions on flotation rate constant (k) and bubble-particle collision efficiency (Ec) of pyrite and chalcopyrite particles were investigated.

high efficiency iron pyrite flotation machine with good performance Pyrite Flotation With Xanthate Under Alkaline Conditions . Xanthate concentration has a positive effect on pyrite flotation, but above a pH of 11, pyrite seems to be strongly . at a high pH (above pH 10), using lime (CaO) or caustic soda.
with pyrite, chalcopyrite needs to be separated from pyrite by flotation, which is usually referred to as the separation of copper and sulfur. To improve the separation efficiency, some scholars have studied
nomic removal of pyrite and other ash forming minerals from coal. However, the flotation process currently used in coal preparation plants is a relatively crude process (Osborne, 1988), not being capable of rejecting pyrite to the desirable levels. The separation efficiency of pyrite from coal by flotation …
Activation efficiency was quantitatively discussed based on an activation index related to the polar group functionality of the activators. The results for activation flotation of pyrite are very well explained using the activation index.
flotation were determined to achieve the maximum grade and recovery of chalcopyrite and the effect of activated pyrite on the chalcopyrite flotation efficiency was investigated. 2. Materials and methods The experiments were performed on copper ore obtained from Sarcheshmeh Copper mine, Kerman, Iran.
The flotation of pyrite using a selection of dithiocarbamate collectors having different alkyl functional groups has been studied. Factorial design techniques were used to determine the importance of the following variables: dithiocarbamate alkyl group type, pH, collector dosage, conditioning time, copper sulphate dosage, and ore particle size or ore condition.
