The church has a bucket about 2/3 full of rock salt, and
water filling the bucket to just over the level of the rock
salt.

I'm not sure if it's calcium salt, or sodium salt.

Any ideas to drying this out, and make it usable again? Or
should I dump it in the trash dumpster, or something? List
it on Recycle?

About the only thing you can do is spread it out and hope the lumps are not
too big and can be broken apart. A 50# bag of rock salt is $8 so I'd not
invest too much time on it.
