There's an interesting question. It is a "salt evaporation pond" , and it is a really old practice of making salt. the colorful south bay of san francisco is thanks to salt farming.
But is refining a mineral really farming? Refining is usually considered industrial - but it was practiced with basically seawater and a flat dirt area for a really long time. But now most of the large ones to map are all part of industrial salt refineries. Sounds like it would be part of an industrial subtag. http://en.wikipedia.org/wiki/Salt_evaporation_pond.
