The application of polymer colloids is a promising approach for bauxite residue dust pollution control. However, due to the existence of synergistic aging, the efficiency of colloid dynamic viscosity to predict the dust control performance of bauxite residue is unclear. Previous studies were also rarely performed under synergistic aging conditions.

- - Red sand dust pollution is a significant issue due to its negative effects on health and the environment, and current solutions include water sprays and polymer stabilizers to suppress dust erosion.
- - The paper assesses the effectiveness of five common laboratory methods for measuring dust erosion resistance in red sand with polymers, identifying advantages and limitations of each method.
- - Results indicate that the penetration resistance test is the most reliable and accurate method, succeeding in various conditions compared to others, and highlights that PAM polymer is more effective than guar gum and xanthan gum for dust control.

Dust emission from the bauxite residue drying areas is of great concern for its serious environmental and health impacts. The application of polymer stabilizers is a promising approach to mitigate such issues. However, limited studies have been done on their application on red sand and the investigation of the effect of polymers on penetration resistance, which is a key mechanical property closely related to the dust control performance.
