PDF A Review on Pyrrhotite Oxidation ResearchGate
·The factors affecting pyrite and pyrrhotite oxidation are similar but the latter has received much less attention Electrochemistry in Mineral and Metal Processing II The Elec trochemical
Nickeliferous pyrrhotite Waste or resource ScienceDirect
·In this paper some historical context behind pyrrhotite processing in the Sudbury area is provided Flow sheet design considerations based on both technical and economic factors are reviewed with the objective of providing the nickel industry with tools for informed decision making on the possibilities for exploitation of this low grade nickel sulphide raw material
PDF Canadian pyrrhotite treatment the history
·Pyrrhotite Po is one of the most abundant sulfide minerals in processing industry and must be rejected in most cases Particularly Po rejection and its selectivity against pentlandite Pn have long been a challenge due to similarities in the mineral composition of the two minerals and the collectorless flotation characteristics of Po Xanthates have been widely
CMP 2025 Laplante Laskowski Symposium on Minerals Processing
·The CMP 2025 Laplante Laskowski Symposium on Minerals Processing Fundamentals will be held on January 20 2025 at the Westin Ottawa Hotel one day before the official opening of the CMP This special symposium invites participants to engage in a full day of focused sessions on minerals processing fundamentals offering valuable insights
Eliminating the adverse effect of the lime on the gold
pyrrhotite is most affected by pulp pH and potential Sun et al 2006 The lime not only plays the role of pH regulator but also acts as a common inhibitor of pyrrhotite and when adjusted by lime the pyrrhotite would be depressed in high alkalinity
Stirred tank bioleaching of nickel and cobalt from pyrrhotite
·Several commercial processes have operated to recover nickel and sometimes iron from pyrrhotite in the Sudbury region dating back to the 1950s and all have ceased operation for environmental or economic reasons; Peek et al 2011 thoroughly reviewed historical pyrrhotite processing flowsheets and their technical challenges environmental
An investigation into the flotation behaviour of pyrrhotite☆
·A number of studies have shown that reaction between pyrrhotite and xanthates produces the oxidation product dixanthogen subject to the oxidation potential being maintained at 200 mV/SHE Miller et al 2005 As with other sulphides the extent and rate of this reaction decrease with increasing pH due to the increasing formation of oxidation products at the
