"Are surfactants effective for iron ore dust control?" by C. R
Wetting reagents are extremely popular dust suppressants. This is the result of beliefs that effective material wetting was the critical factor in reducing airborne dust. Unfortunately, personnel at an iron ore facility reported wetting reagents were not effective for iron ore. To determine which types of reagents would be effective for iron ore, a novel laboratory …
