ROUND TABLE TOPICS
Round Table topics include the symposium topics above as well as some specific topics described below: (Participants are free to add topics as per their interest)
Sampling
Errors in sampling and consequences in metal accounting.
Sampling improvement for the advance of the plant performance.
Grinding Strategies
Improving the efficiency of this least efficient circuit in the concentrator
Improving the shape and particle size distribution for good metal recovery in flotation or in gravity separation
Improving the electrochemical potential of the grinding circuit product
Selectivity in Flotation
Minimizing disturbances in the sulphide flotation processes of problematic minerals such as the iron sulphides pyrite and pyrrhotite, and talc
Collectors in Flotation
Improving sulfide flotation using ``green collectors``, which do not produce carbon disulphide and are more selective.
Improving metallurgical performance as compared to the single xanthate arrangement.
Modern Process Mineralogy
Dealing with the treatment of difficult and complex ores that require more sophisticated characterisation and understanding.
Dealing with the treatment of lower grade minerals containing deleterious elements that require tailored treatment.
Applying a more sustainable approach including environmental and societal considerations in process mineralogical assessment providing the critical information that stands between failure or collapse and survival or success of some mining operations.
