You could evaporate the brine and make sea salt. You basically remove the last bit of water after most of the salt has crystallized and you get pure salt and the impurities concentrate in the left over water. It should be more efficient than traditional sea salt production as the solution starts out more concentrated. note that I'm doing my PhD in materials science and focus on biomineralization.
