In the mineral processing process, foam control is a key link that affects production efficiency and concentrate quality. Excessive foam leads to slurry overflow, unstable equipment operation, and reagent waste, and ultimately reduces mineral processing recovery and product grade. Chemi Tech focuses on the development and application of defoamers for mineral processing, aiming to help mineral processing enterprises respond to foam challenges precisely and efficiently.
In response to market pain points, Chemi Tech has conducted an in-depth analysis of the root causes of foam: in flotation operations, the interaction between frothers and mineral particles tends to generate stable foam; during the thickening and dewatering stages, fine mineral particles and residual reagents can also cause foam to accumulate. Such foam not only hinders process observation and operation but also causes the loss of valuable minerals and increased energy consumption.
Our solution is based on in-depth research into the properties of different ores and process conditions. Chemi Tech defoamers use specific surface-active ingredients that can quickly destroy the foam film structure without affecting flotation selectivity or reagent performance. The products offer good chemical stability, are suitable for acidic or alkaline slurry environments, and are economical in dosage.
The specific application steps include: first, determine the foam characteristics and the appropriate defoamer type through lab tests; second, calculate the dosing point and dosage based on slurry flow and foam volume, and continuous dripping is usually recommended at the inlet of the flotation cell or thickener; then, monitor the foam layer thickness in real time during production and adjust the dosage to achieve the best control effect; and finally, regularly evaluate the impact of the defoamer on mineral processing indicators and optimize the usage plan.
An iron ore processing plant once faced the problem of excessive flotation foam and serious concentrate overflow. After an on-site diagnosis by our engineers, a dedicated defoamer was recommended and added separately at the roughing and scavenging operation points. After the adjustment, the foam layer dropped rapidly, the flotation machine resumed smooth operation, the concentrate recovery rate improved, and the extra consumption of frother was reduced, achieving a significant improvement in benefits.
