CGA useful in assessing flotation performance

AN ACARP project has explored the role coal grain analysis can play in better understanding the process and predicting flotation outcomes from resource data.

Four full-scale flotation circuits were sampled and each of the feed, concentrate and tailings samples were subjected to CGA, which allowed investigation of flotation response by size.
 
For these circuits, reagent dosages were varied to measure the response of the different grain types. The results were assessed considering traditional free flotation and fine float sink test data.
 
"This project has demonstrated further application of CGA as a tool to provide a more fundamental basis for modelling flotation performance," ACARP said.
 
"The CGA data provide a very clear picture of where valuable product coal is being lost to tailing, thus providing a tool for flotation cell and flotation reagent...
