Fill each clean clam shell with mixture, pressing tightly into shell. Arrange on a baking sheet, and sprinkle lightly with paprika. (Stuffed shells may be covered and frozen at this point for later use.) Bake in the preheated oven for 20 minutes, or until golden brown and sizzling. If frozen, bake at 350 degrees F (175 degrees C) for 30 minutes, or until warmed through. Serve warm on a platter with lemon wedges.
The roads we ride or drive on and the buildings we live learn and work in all contain minerals. Below is a selected list of commonly used metallic and nonmetallic minerals, ore minerals, mineral byproducts, aggregates, and rock types that are used to make products we use in our daily life. Aggregates Natural aggregates include sand, gravel, and crushed stone.
Finding and exploiting mineral deposits requires the application of the principles of geology that you have learned throughout this course. Some minerals are used as they are found in the ground, i.e. they require no further processing or very little processing. For example-gemstones, sand, gravel, and salt (halite) .Most minerals must be processed before they are used. For example: 1  Iron is the found in abundance in minerals, but the process of extracting iron from different minerals varies in cost depending on the mineral.2  Aluminum is the third most abundant mineral in the Earth's crust. Aluminum is the third most abundant mineral in the Earth's crust. 2  It occurs in the most common minerals of the crust-the feldspars (NaAlSi3O8, KalSi3O8, & CaAl2Si2O8, but the cost of extracting the Aluminum from these minerals is high.
