FLOTATION: Eriez commissions automated four-stage lab column circuit

ERIE, Penn. – Eriez® Flotation Division (EFD) announces the commissioning of a fully automated, four-stage lab scale column circuit for flotation testing on sulphide and industrial minerals. The flotation circuit can be altered to accommodate multiple circuit configurations ranging from one (i.e. rougher) to four (i.e. rougher-scavenger-cleaner-recleaner) unit operations, dependent upon the characteristics of the feed ore. The circuit is also capable of incorporating re-circulating loads. The automated circuit can be utilized to conduct steady-state column flotation tests at feed rates of up to 15 kg/h. Operating parameters such as air flow rate, wash water flow rate, reagent addition rates and pH level are regulated using a programmable logic controller. [caption id="attachment_1003717345" align="alignleft" width="300"] The new four-stage lab column flotation circuit is only part of Eriez’s in-house metallurgical expertise.[/caption] EFD can provide detailed analysis of most flotation circuit configurations using laboratory equipment ranging from grinding mills to bench top and continuous conventional and column flotation cells. Typical tests range from exploratory batch testing to the evaluation of multi-stage flotation circuits. EFD’s analytical lab is capable of x-ray fluorescence, inductively coupled plasma optical emission spectrometry, sulphur analyzer and laser particle size analyzer. The lab can quickly conduct in-house assays and improve turnaround time on testing. For more information about EFD’s in-house lab services, visit http://EriezNews.com/nr403.
