Holistic Froth Control With Interfoam ® D5635 Defoamer.

An Australian polymetallic processing plant engaged InterChem to investigate alternative defoamers to address ongoing froth stability issues that were negatively impacting plant performance. Highly stable froths were impairing froth pumping and throughput, while the incumbent defoamer required high dosage rates that increased operating costs and depressed valuable mineral recovery. The plant required a defoamer capable of effectively suppressing concentrate froths at lower dosages without compromising flotation performance.
