Abstract
A method and formulation are shown for capping the exposed surface of an aggregate of materials, such as exposed land areas with fine particulate mining wastes. A mineral formulation is prepared by mixing together lime, a pozzolanic component, a sulfate component, a cellulosic component and water. The mineral formulation is applied to the exposed aggregate and is allowed to harden to form a surface coating thereon. A seed component or a coloring additive can be incorporated within the slurry for revegetating land areas and to enhance the esthetic appearance of the hardened cap.
Claims17
An improved method of capping an exposed surface of an aggregate of materials, the materials which tend to become airborne due to environmental factors, the method comprising the steps of:
- mixing together a slurry of lime, a pozzolanic component, a sulfate component, a cellulosic component an amine component, a glue component and water and wherein the sulfate component is selected from the group consisting of sodium sulfate, potassium sulfate, magnesium sulfate, manganese sulfate, ammonium sulfate, aluminum sulfate and lithium sulfate;
- applying the slurry to the exposed surface of the aggregate;
- and
- allowing the slurry to harden to a solid mass which substantially covers the exposed surface to be capped.
An improved method of capping an exposed surface of an aggregate of materials, the materials which tend to become airborne due to environmental factors, the method comprising the steps of:
- first blending together a dry mineral formulation comprising lime, a pozzolanic component, a sulfate component and a cellulosic component;
- thereafter preparing a liquid slurry by adding the previously blended dry mineral formulation to a total amount of water, the ratio of dry mineral formulation to total water being from about 1:2 to 1:4 by weight water;
- applying the slurry to the exposed surface of the aggregate;
- and
- allowing the slurry to harden to a solid mass which substantially covers the exposed surface to be capped.
An improved method of capping a land area having an exposed surface of particulate materials, the particulate materials which tend to become airborne due to environmental factors, the method comprising the steps of:
- mixing together a slurry of lime, a pozzolanic component, a sulfate component, a cellulosic component, an amine component, a glue component, a coloring additive and water and wherein the sulfate component is selected from the group consisting of sodium sulfate, potassium sulfate, magnesium sulfate, manganese sulfate, ammonium sulfate, aluminum sulfate and lithium sulfate;
- applying the slurry to the exposed land area;
- and
- allowing the slurry to harden to a solid mass which substantially covers the exposed surface to be capped.
An improved method of capping a land area having an exposed surface of particulate materials, the particulate materials which tend to become airborne due to environmental factors, the method comprising the steps of:
- mixing together a slurry of lime, a pozzolanic component, a sulfate component, a cellulosic component an amine component, a glue component and water and wherein the sulfate component is selected from the group consisting of sodium sulfate, potassiumsulfate, magnesium sulfate, manganase sulfate, ammonium sulfate, aluminum sulfate and lithium sulfate;
- incorporating a seed component within the slurry;
- applying the slurry to the exposed land area;
- and
- allowing the slurry to harden to a solid mass which substantially covers the exposed surface to be capped, the hardened slurry serving as a matrix to hold the seed components during early stages of growth.
