My perspective would be that "slime" is a generic term for material which is not part of the main stream of a chemical process but has value as a by-product. It occurs in a number of kinds of metal processing. Electrolytic processing in particular can recover a LOT of rare metals in tank slimes. Because slimes can have many origins, I would hesitate to generalize about color or weathering.

Thanks Tony,

I wasn't trying to generalize, but I should have mentioned that I was talking ONLY about zinc sulfide slime which has a very particular meaning in context of acidic mine environments of the eastern U.S. I assumed that's what the original post was about but I wasn't very clear.

There are many other byproducts that are called slimes (or more technically biofilms) that would exhibit many different color variations.
