Andy I don't believe there is a course as such out there in brine processing as there is no clear cut right or wrong way of doing it. It's a process that takes years to develop from pumping wells to a viable commercial operation, so as you could imagine, process techniques differ from one brine operation to the next and is developed in house on the fly so to speak and is very tightly held.
Your best bet is probably making contact with the companies themselves and seek advice direct the best possible options to potentially get your foot in the door.
GL and enjoy South America, I hear the weather is nice.
