Natural Resources Natural resources are materials provided by the Earth that humans can use to make more complex products. Natural resources are segregated into two types. -Renewable - Non-Renewable

Renewable Resource oxygen fresh water timber solar energy biomass

Non-Renewable Resources Coal Crude oil Uranium Natural Gas

Mineral resources Types of Mineral Resources: Minerals in general have been categorized into three classes’ fuel, metallic and nonmetallic. Ore A rock which a valuable or useful substance occur at a high concentration where it is economically viable to mine

Metallic resources IRON, ALUMINUM, COPPER AND CHROMIUM Uses -Iron Buildings, hips, road vehicles, appliance cases, -Aluminum Packaging, vehicles, windows frames etc. -Copper Electric cables, wires, water pipes -Chromium Stainless steel I. Metallic mineral are those minerals which can be melted to obtain new products. II. When hit, they do not get broken.

Non-metallic resources SAND, GRAVEL, LIMESTONE, GRANITE AND SLATE Uses Sand Builders’ mortar, glass Gravel Concrete Limestone Building blocks, roads, glass Granite Blocks, tiles Slate Roof slates I. Non-metallic minerals are those which do not yield new products on melting. II. When hit, they may get broken into pieces.

Pegmatites The final water-rich residue of granitic intrusions. Enriched in “reject” elements. Ex. Silica, Water, Lithium, Tantalum, Niobium, Boron, Beryllium, Gold, and Uranium. Common or simple pegmatites contain typical granite minerals plus black tourmaline. Lepidolite mica typical indicator of complex pegmatites. Sources of gems, mica, feldspar, lithium, rare earths. (including col-tan)

Hydrothermal Solutions Hydrothermal activity is the circulation of water through hot volcanic rocks and magma. This process dissolves minerals in to smaller bits. Forms fumaroles- volcanic vents emitting gases, some charged with dissolved minerals.

disseminated deposit Deposit in which usually finegrained ore minerals are scattered throughout the rock. Large, disseminated deposits form important sources of ore.

Building materials Building material is any material which is used for construction purposes. Many naturally occurring substances, such as minerals are used. MINERALS HOUSEHOLD ITEM Copper, Zinc, Nickel, Chrome, Clay, Iron Plumbing Fixtures Stone, Brick, Iron Fireplace, Stove, Furnace Limestone, Clay, Shale, Gypsum, Aggregate Foundation, Driveway Trona, Silica, Feldspar Windows (Glass)

Industrial minerals are geological materials which are mined for their commercial value. They are used in their natural state or after beneficiation either as raw materials or as additives in a wide range of applications. Typical examples of industrial rocks and minerals. -Limestone -Clays -Sand -Gravel -Diatomite kaolin -Bentonite -Silica Some examples of applications for industrial minerals -Construction -Ceramics -Paints -Electronics -Filtration -Plastics -Glass
