How to Solve Froth Flotation Foam Problems? Chemi Tech's Efficient Defoamer Provides Professional Solutions

In mineral processing froth flotation operations, froth is a key medium for mineral separation, but uncontrolled foam becomes a persistent production headache. Excessive, overly sticky, and poorly flowing foam leads to launder overflow, fluctuating concentrate grade, reduced recovery rates, and can even force production line shutdowns, causing both resource and economic losses. Traditional defoaming methods often address symptoms, not the root cause, or introduce harmful components that affect downstream processes.

Confronting the core pain points of flotation foam, Chemi Tech leverages deep understanding of mineral processing to develop a series of high-efficiency flotation defoamers. Our solution goes beyond eliminating surface foam, aiming to regulate the foam system at its source and achieve a precise balance between foam stability and fluidity.

Chemi Tech's targeted solution follows these steps: First, our technical team conducts an on-site analysis of ore properties, reagent scheme, and foam characteristics to accurately diagnose the cause of foam. Second, based on the foam's foaming capacity, viscosity, and solid content, we select a matching high-efficiency defoamer from our product lines, including silicone compounds, polyether modifications, and specialty alcohols. Third, we provide samples for laboratory flotation tests to verify defoaming performance and impact on concentrate indicators, ensuring no adverse effects. Finally, we determine the optimal addition point and dosage and establish operating procedures for smooth integration.

We assisted a processing plant dealing with complex polymetallic ore. The plant faced excessively thick and sticky foam in the rougher flotation stage, causing severe launder overflow, high labor intensity for operators, and loss of fine valuable minerals with the foam. Through on-site assessment, we recommended a custom-designed high-penetration defoamer from Chemi Tech. After adding it at a specific point in the scavenger froth launder, the foam layer quickly became thinner and more fluid, fundamentally curbing overflow. The flotation circuit regained stability, the recovery efficiency of valuable minerals improved, and the defoamer usage did not interfere with foam activity in the cleaner stage or final concentrate quality, earning recognition from the production team.

Choosing Chemi Tech means selecting not just a product, but a reliable process support system. We are committed to helping mineral processing enterprises overcome foam control challenges, achieving smooth operations, optimized indicators, and controllable costs.
