Novel binders and a compacted salt containing those binders are provided. The binders comprise an aqueous solution or dispersion of sorbitol and an alkali metal phosphate. The binder is contacted with salt crystals heated to elevated temperatures. After binder contact, the coated salt crystals are passed through a compactor where elevated temperatures and pressures cause the salt to melt and then recrystallize as a sheet that can be broken into pieces. The final salt product has the binding agent substantially uniformly dispersed therethrough, resulting in a salt that has high strength and is resistant to mushing. The inventive products are particularly useful as a water softening salt. |
