Mineral, nutritional, cosmetic, pharmaceutical, and agricultural compositions and methods for producing the same
Mineral, cosmetic, pharmaceutical, agricultural, nutraceutical, and other compositions are produced using a mineral composition containing minimal concentrations of cadmium, lead, arsenic, and mercury and containing relatively high concentrations of micro and macro mineral elements, of rare earth elements, of calcium, and of silica. The mineral concentrations are produced by processing naturally occurring clay soil to concentrate mineral elements naturally occurring in the soil.
1. A method for treating a clay soil, a mixture of clay soils, or a mixture of clay soils and leonardite, consisting of, one acid treatment step, a settling step, a separating step, and a concentrating step,
wherein the one acid treatment step consists of admixing a clay soil, a mixture of clay soils, or a mixture of clay soils and leonardite, with water in an amount at least two times the weight of the soil and an acid to produce a water-acid-soil slurry, wherein the amount of acid is 0.25% to 7.5% of the weight of the water;
wherein the settling step consists of allowing solids from the water-acid-soil slurry to settle;
wherein the separating step consists of separating the liquid of the water-acid-soil slurry from the settled solids wherein the solids comprise substantially all of the silica and aluminum from the clay soil, mixture of clay soils, or mixture of clay soils and leonardite; and
wherein the concentrating step consists of concentrating the separated liquid to form a liquid extracted mineral element composition comprising a lower amount of silica and aluminum than the clay soil, a mixture of clay soils, or a mixture of clay soils and leonardite.
2. The method of claim 1 , wherein the water is purified by reverse osmosis.
3. The method of claim 1 , wherein the pH of the extracted mineral element composition is less than 4.5.
4. The method of claim 3 , wherein the acid is an edible acid.
5. The method of claim 4 , wherein the edible acid is citric acid.
6. The method of claim 4 , wherein the edible acid is phosphoric acid.
7. The method of claim 1 , further comprising drying the concentrated liquid to form a dry extracted mineral element composition.
8. The method of claim 7 , wherein drying comprises spray drying the liquid extracted mineral element composition.
