By maintaining low temperatures, the integrity of the natural delicate state of plant derived minerals is maintained. They are concentrated from the 70 million year old organic humic shale deposits of The Rockland Mind by The Rockland Corporation. The humic shale is mined in the natural dry state as it has existed for millions of years. It is then ground to smaller aggregates and placed in stainless steel vats, where it is leached slowly. No acids are used.
Negative pressure is applied which makes the concentration more efficient at low temperatures.
Only the water is removed and the solid plant-derived colloidal minerals are all that are present, but in a highly concentrated form. When the leaching is complete, the mother liquor contains 38,000 milligrams of the 7 major minerals and 70 trace minerals per quart of liquid. Metallic minerals carry a positive charge in their ionic form in solution and, in general, are just not very soluble. Scientifically, they are called hydrophobic because they are not very soluble in water. Minerals that have been assimilated by plants are hydrophilic, so they are very water soluble.
