This process can recover all of the minerals as high purity industrial minerals, including capturing the calcium and sulfate as agricultural grade gypsum and boron as high purity boric acid. In addition the process allows the use of low cost lime or dolime to produce valuable magnesium hydroxide.

The method also includes forming a second surface of the second part where the second surface has a second shape and the first shape and the second shape are substantially complementary shapes. Projections form at least a portion of the second surface in a preselected pattern, and are configured to produce a friction fit between the first surface and the second surface when the first surface and the second surface are biased against each other. The projections have an average elastic compressive range substantially equal to the surface roughness average.
