Importance of minerals to society and mining mineral ores

Objectives of this report: To understand and identify the important minerals used in society To describe how minerals are found, mined, and processed

WHAT ARE MINERALS? A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic, chemical composition, crystal form, and physical properties. -

WHY ARE MINERALS ESSENTIAL TO SOCIETY? Minerals play a very important role in ensuring our world's demand for energy, building infrastructure, advancing science and technology, sustaining the global food supply, predicting and reacting to natural disasters, and everything in between. -

Important minerals used in society: Fluorite - A mineral composed of calcium fluoride, used in toothpaste for its fluoride content, which helps prevent tooth decay. Talc - The softest mineral on the Mohs hardness scale, often used in cosmetics like face powder for its smooth texture. Halite - A mineral composed primarily of sodium chloride, used to enhance the flavor of food. Iron - A metal used in stainless steel kitchen wares, often combined with chromium to form a durable, non-corrosive alloy. It can also be combined with carbon to create a strong and durable material used in skyscrapers. Chromium - A metal used in stainless steel to enhance its corrosion resistance and durability.

Aluminum - A lightweight, corrosion-resistant metal used in various kitchen wares, such as casseroles, known for its good heat conductivity. Silicon - A metalloid used in electronics, particularly in semiconductors for gadgets like cellphones and computers. Silver - A precious metal with excellent electrical conductivity, often used in electronic components. Gold - A highly conductive and corrosion-resistant precious metal, also used in electronics. Copper - A ductile metal with high electrical conductivity, commonly used in electrical wiring. Phosphate – used in the production of fertilizers and feed additives for live stocks.

Titanium - A strong, lightweight metal known for its biocompatibility, making it ideal for medical implants and tools. Gypsum - A soft sulfate mineral used in plaster casts for setting broken bones. Uranium - A radioactive mineral used as fuel in nuclear power plants to generate electricity. Lithium - A light metal used in rechargeable batteries, particularly for electric cars. Cobalt - A metal used in batteries, often combined with lithium to improve energy density. Zinc - A metal used in dry cell batteries, particularly in the electrodes. Cadmium - A metal used in rechargeable batteries and other types of dry cells.

Limestone - A sedimentary rock composed mainly of calcium carbonate, used in concrete production. Lime - A material derived from limestone, used in construction to improve the strength and durability of concrete. Chalk - A soft, white, porous form of limestone, also used in cement and construction. Quartz - A hard, crystalline mineral used in the production of glass. Granite - A coarse-grained igneous rock used for flooring due to its durability and aesthetic appeal. Aluminum - Used in construction for window and door panels due to its lightweight and corrosion-resistant properties.

Nickel - A metal used in batteries and other applications for its durability and resistance to corrosion. Phosphorus - Another key element in fertilizers, important for root development and flowering in plants. Potassium - An essential nutrient in fertilizers that helps plants resist diseases and improve water use efficiency. Calcium - A mineral essential for strong bones and teeth, commonly found in dietary supplements. Magnesium - A mineral important for muscle function, nerve function, and overall health, often included in supplements. Feldspar – used in glass and ceramic industries, soaps, insulating compositions and bond for abrasive wheels.

Industrial minerals - Non-metallic minerals used for their physical or chemical properties in industries, like limestone (used in cement), quartz (used in glassmaking), and talc (used in cosmetics)

gemstones - Minerals or materials cut and polished for adornment or decoration due to their beauty, rarity, and durability like diamonds, rubies, sapphires, and emeralds.

Ore minerals - Minerals from which metals or valuable elements can be extracted profitably, such as hematite (iron ore), chalcopyrite (copper ore), and bauxite (aluminum ore).

Mining is the process of mineral extraction from a rock seam or ore. Modern mining technology uses geophysical techniques that involve measuring the magnetic, gravity and sonic responses of rocks above and around a prospective mineral ore body. What is mining?

THERE ARE TWO METHODS IN MINING: Surface Mining Underground mining &

Surface Mining is used to extract ore minerals near the surface of the earth. The soil and rocks that covered the ores are removed through blasting. Blasting is a controlled use of explosives and gas exposure to break rocks. Some examples of surface mining are: 1.Open-pit mining 2. Strip mining 3. Dredging

1. Open-pit mining - This is the most common type of surface mining. Open pit means a big hole (or pit) in the ground. The pit in mine is created by blasting with explosives and drilling. It is used to mine gravel and sand and even rock. 2. Strip mining - Strip mining involves removing a layer of earth to access a deposit, extracting the material, and then repeating the process in parallel strips. The waste from each new strip is placed in the previous strip. This method is commonly used for mining coal, phosphates, clays, and tar. 3. Dredging - This is the process of mining materials from the bottom of a body of water, including rivers, lakes, and oceans.

Underground mining - is used to extract the rocks, minerals and other precious stories that can be found beneath the earth’s surface. In underground mining, miners need to create a tunnel so they can reach the ore minerals. This kind of mining is more expensive and dangerous as compared to surface mining because miners need to use explosive devices to remove the minerals from the rocks that cover them. Underground mines

Mineral processing is the process of extracting minerals from the ore, refining them, and preparing these minerals for use. The primary steps involved in processing minerals are: 1. Sampling – is the removal of a portion which represents a whole needed for the analysis of this material. 2. Analysis – is important to evaluate the valuable component in an ore. This includes chemical, mineral and particle size analysis. 3. Comminution – is the process where the valuable components of the ore are separated through crushing and grinding. This process begins by crushing the ores to a particular size and finishes it by grinding the ores into a powder form. 4. Concentration – involves the separation of the valuable minerals from the raw materials 5. Dewatering – uses the concentration to convert it to usable minerals. This involves filtration and sedimentation of the suspension and drying of the solid materials harvested from this suspension.
