Hi Guys, Let me explain my problem, and hopefully you can help me come to a solution. I have been asked to model a Calcium Sulfate dihydrate stockpile (A cone shape) that is washed with water to remove impurities of MgCl2 and KCl. My job is to determine how much water should be used given a size of a stockpile to maximize the removal of impurities but minimize the amount of water used. Does anyone have any ideas? Some ideas I have/assumptions I think I should use:
If anyone has any ideas, or any good references. That would be awesome. Thanks, James The amount of water used determines how far the water penetrates deep the water penetrates the Depending on the amount of water used, changes the amount that the If a lot of water

You're going to have to give us some idea about the properties that will maximize the removal of impurities. Are we really just talking about maximizing the ratio of the water that comes into contact with CaSO4 · 2 H2O to that which doesn't? I'd think we'll need some info on the porosity of the pile. Surely this problem has been solved before (if you are actually doing this). Do you have an engineer up the work chain from you you can consult?
