Describe the use of any four minerals
Answers
Answer:
Aggregates
Natural aggregates include sand, gravel, and crushed stone. Aggregates are composed of rock fragments that may be used in their natural state or after mechanical processing, such as crushing, washing, or sizing. Recycled aggregates consist mainly of crushed concrete and crushed asphalt pavement.
Aluminum
Aluminum is the most abundant metallic element in the Earth's crust. Bauxite ore is the main source of aluminum. Aluminum is used in automobiles and airplanes (36%), bottling and canning industries (25%), building and electrical (14%) and in other applications (25%).
Antimony
Antimony is a silvery-gray, brittle semi-metal. It rarely occurs in nature as a native element, but is found in a number of different minerals. Antimony is used principally for flame retardants as well as in ammunition and automotive batteries and as a decolorizing agent in glassmaking.
Basalt
Basalt is an extrusive igneous rock. Crushed basalt is used for railroad ballast, aggregate in highway construction, and is a major component of asphalt.
