A fourth displacement is required, initially, to saturate the ore. Since a typical heap contains 20% moisture, 95% recovery (of the dissolved value content) requires application of 0.8 metric tons of solution to each metric ton of ore. In gold heaps, typical practice is to apply 1.3 metric tons of solution per metric ton of ore. The importance of choosing the correct ore stacking method cannot be underestimated.
