In mineral flotation operations, froth is the key carrier for mineral separation, but uncontrolled froth becomes a stubborn production problem. Excessive, sticky froth with poor fluidity causes tank overflow and bubbling, fluctuations in concentrate grade, and declining recovery; in more severe cases it forces production lines to halt, causing both resource and economic losses. Traditional defoaming methods often treat only the symptoms, or introduce harmful components that affect downstream processes.
Facing the core pain points of flotation froth, Chemi Tech, with a deep understanding of mineral processing technology, has developed a series of high-efficiency flotation defoamers. Our solutions go beyond eliminating surface froth, focusing on regulating the froth system from the root to achieve a precise balance between froth stability and fluidity.
Chemi Tech's targeted solutions follow these steps. First, the technical team goes on site to analyze ore properties, reagent systems and froth characteristics, precisely diagnosing the causes of froth. Second, based on the frothing strength, viscosity and solids content, we select the matching high-efficiency defoamer from our silicone compound, polyether-modified and specialty alcohol product lines. Third, we provide samples for laboratory flotation tests to verify the defoaming effect and its impact on concentrate indicators, ensuring no negative influence. Finally, we determine the optimal dosing point and dosage, establish operating procedures, and achieve smooth integration.
We once helped a processing plant treating complex polymetallic ores solve its problem. The froth layer in the rougher stage was overly thick and sticky, the froth troughs overflowed severely, operators faced heavy labor intensity, and fine-grained valuable minerals were lost with the froth. After on-site evaluation, we recommended a customized high-penetration defoamer from Chemi Tech. After dosing at a specific point in the scavenger froth trough, the froth layer quickly thinned and its fluidity improved, fundamentally curbing the overflow problem. The flotation process regained stability, the recovery of valuable minerals improved, and the defoamer did not interfere with froth activity in the cleaner stage or the final concentrate quality, earning recognition from the production team.
Choosing Chemi Tech means choosing not only a product, but also 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.
