In the process of alumina bayer process, especially by the Bayer method, a large amount of foam is often produced in the mineral slurry, which reduces the decomposition speed of the solution, weakens the efficiency of the evaporator, causes the increase of sodium carbonate content in the solution, reduces the flow of sand material, affects the coordination of production and loading workers. The foaming in the seed-sorting process of the settling tank will lead to the failure of the desired classification effect, even the failure to use the settling tank for classification treatment, which is not in line with the production process standards.
Rickman RK-900P is a kind of refined non-silicon emulsion, which is transparent liquid in appearance. It has strong defoaming and antifoaming ability, and can withstand high temperatures and high pressure and strong acids and alkalis. Adding a small amount of alumina defoamer to the foaming system helps to make the alumina hydroxide better achieve crystal transformation at high temperatures, maintain the balance of liquid amount in the circulation system, and evaporate and concentrate to meet the requirements of the Bayer process slurry. The defoamer can also effectively improve the quality of alumina, and has no adverse effects on bauxite dissolution, red mud sedimentation, aluminate solution decomposition, mother liquor evaporation, and other processes. In the process of alumina production, the defoamer will not undergo hydrolysis, and long-term work will not affect their foam inhibition. In addition, it can also improve the purity of the overflow liquid during the separation of red mud.
