Copper Sulfide Flotation Circuit The pulp from the Conditioner is treated in a 10 cell Sub A Flotation Machine and a 4 cell Sub A Flotation machine Sometimes conditioners are not provided; however their use insures that reagents are thoroughly mixed into the pulp ahead of flotation Summary of Porphyry Copper Sulfide Processing
Sulfide flotation refers to the electrochemical process in which sulfide minerals are recovered by froth flotation involving the transfer of electrons between different sulfide minerals 9 Flotation Circuits Flotation circuit configuration on most gold mines can be divided into a number of categories viz open circuits with no cleaning
The free milling ore characteristics of the Fort Knox gold deposit are ideal for studying gold and silver behaviors in various processing circuits without serious interference of sulfide minerals and other refractory factors A galvanic effect leads to faster silver dissolution than gold dissolution and as a result the Au/Ag solution concentration ratio increases through the
In the pressure leaching process sulphide ores and concentrates are leached in autoclaves at temperatures of 200 to 220°C and a pressure of about 3000 kPa Schlesinger et al 2011 An oxidizing agent usually oxygen is required to oxidize sulphide ions to sulphate ions The oxidation of sulphur to sulphate is exothermic; consequently a

The HydroFloat is an innovative fluidized bed separator that can substantially increase the upper particle size that can be successfully treated by flotation Recent studies conducted using laboratory bench scale and pilot scale equipment indicate that this technology can be used to float coarse sulfide middlings that cannot be recovered by conventional flotation machines
Syama is a robust long life asset comprising a underground mine and associated sulphide processing circuit along with satellite open pit operations which provide ore feed to a separate oxide processing circuit Mako is a high quality open pit gold mine which Resolute has owned and operated since August 2019
The Hellas Gold plant is located at Olympias Halkidiki Greece It employs sulphide mineral processing in consecutive flotation steps leading to the production of galena PbS silver Ag concentrate Pb 63% grade and 85% recovery Ag 1850 g/t grade and 85% recovery sphalerite concentrate ZnS Zn 50% grade and 85% recovery and gold
In normal practice a recovery of over 90% of the copper which is present as a sulphide is generally possible whatever the flotation process or circuit employed As regards the average grade of concentrate no more can be said than that it depends on the class of the copper bearing minerals present and their mode of occurrence and on the
A continuous pilot plant campaign has been conducted over the 2021 2022 period to demonstrate the technical feasibility of Metso Outotec s novel BIOX ® MesoTHERM process for treating high grade copper gold concentrates The concentrate hosted refractory gold as well as primary and secondary copper sulphide minerals
