An aqueous magnesium oxide suspension is disclosed which comprises from about 8 to about 50% by weight MgO, based on the combined weight of water, MgO, suspension aid, and surface active dispersant. Suspension aids such as zanthan gum and guar gum are utilized in the presence of surface active lignin sulfonate dispersants to provide a highly stable concentrated suspension, useful as a base for fertilizers, animal feeds, etc. |
