The ores obtained from the earth's crust are named as minerals. The science that works these minerals is known as Metallurgy.
Separation of minerals is done by various procedures. It is not really obtained directly as a pure organic material. It is a mixture of various dust particles. Refining yields the product firing from particles and the material obtained is named as minerals.
Minerals may be present in ground water. So far Uranium, Thorium, Deuterium are identified. Minerals are the adequate products. Their presence is limited. Conservation of mineral resources is very important for future use. If their use is at the same late we have to run short of this resources in no time resulting in energy crisis. Their use must be balanced in ecosystem to avoid energy crisis.
The overall objectives in conservation of mineral resources are
Nitrogen: it is the constituent of amino acids, proteins, hormones, enzymes, coenzymes, chlorophyll, vitamins, cytochromes, ATP.
Phosphorus: it is the constituents of nucleotides, nucleic acid, certain proteins, phospholipids, NAD+, NADP+
Potassium: it helps in the synthesis of proteins, cell membrane, and osmotic potential. It also stimulates opening and closing of stomata. It helps in maintaining turgidity of cell. It also acts as an activator of some enzymes.
Calcium: it is present as calcium pectate in middle lamella, development of roots and stem apices. It helps in cell membrane permeability. Like phosphorus, it also acts as n activation of enzymes. It takes part in the organization of mitotic spindle.
Magnesium: it is a major constituent of chlorophyll. It is an activator of phosphate metabolism in respiration and photosynthesis. It helps in DNA and RNA synthesis, fat synthesis, carbohydrate metabolism and maintenance of ribosomes.
Sulfur: it is a constituent of certain amino acids, proteins, vitamins, coenzyme A and ferredoxin.
Iron: it is a constituent of ferredoxin and cytochromes and nitrogenase. It is an activator of catalase and is required for chlorophyll and protein synthesis. It also helps in the development of chloroplasts.
Manganese: it plays a major role in hydrolysis of water and activates carboxylases and oxi-reductases. It is connected with respiration, photosynthesis and nitrogen metabolism.
Molybdenum: it acts as an activator of certain enzymes involved in nitrogen metabolism including nitrate reduction and nitrogen fixation. It also promotes oxidation-reduction reactions.
Boron: it helps in calcium metabolism, pollen germination, cell differentiation, carbohydrate transport, root nodulation, cell elongation and differentiation.
Copper: it acts as an activator of certain enzymes. Copper takes part In electron transport as plastocyanin and cytochromes oxidase.
Zinc: it helps in auxin synthesis and activates certain carboxylases and dehydrogenases.
Chlorine: it helps in hydrolysis of water. It maintains solute concentration and ionic balance along with Na and K. It is the activator of amylase.
Following are some of the strategies that can be followed for the conservation of high quality mineral resources.
Securing the effective and the efficient use of minerals in accordance with sustainability principles can only be achieved if all those involved in producing and using minerals and their products will make a commitment to ensuring that development becomes more sustainable.
