I've wondered why desal hasn't also paired up with ocean mineral extraction. It seems like the two would go well together.

Even when talking about RO, you'd think diverting all or part of the brine water for evaporation would reduce the cost of extraction. You'd have water with more concentrated minerals which would give you a higher yield per evaporation cycle.

Also, it'd be nice if we could bring back magnesium extraction from ocean water.

Would like to see investment into removing dissolved co2, bicarbonate ion from the ocean as well.

What ever happened to that company that was going to extract materials for concrete from seawater?
