Quell^® Defoamers / Anti-Foaming Agents for the Mining and Crop Nutrition Industries

Quell® defoamers / anti-foaming agents and dosing systems are custom-developed for the mining industry to beneficiate oxide ores such as phosphate and industrial minerals. They are designed to meet the requirements of specific mineral deposits, mineral pumping and handling equipment, and froth flotation process conditions. Quell® defoamers are also used in wet-process phosphoric acid production to maintain degassing performance of entrained gases and break surface foam, due to their ability to remain functional for longer periods of time within phosphoric acid reactors. In addition, the use of Quell® defoamers in downstream ammonium phosphate granulation and fertilizer production processes facilitates higher capacity utilization and optimal finished fertilizer output.
