* D. Metal bearing solutions cool to form hydrothermal ore deposits. * E. Black Smokers – upwelling magma solidifies. Miniature volcanoes shoot hot‚ black‚ mineral rich water through vents of solidified magma on the seafloor. Support chemosynthetic organisms. * Manganese Nodules (Pacific Ocean) – ore nodules crystallized from hot solutions arising from volcanic activity. Contain manganese‚ iron copper and nickel.

Metals are mined from ores‚ considering yield to see if it is economically viable for a business to mine at a particular site. However‚ due to environmental damage and global warming‚ recycling has increased globally to create a sustainable future. By examining the cost and energy expenditure of recycling and extracting aluminium we can understand why recycling is a better choice than extracting metal from its ore. Discuss the importance of predicting yield in the identification‚ mining and

Abundance and Extraction of Metals 1. a Mineral - A mineral is a naturally occurring inorganic solid‚ with a definite chemical composition‚ and an ordered atomic arrangement. b Ore - Deposit in the Earth of valuable metals contained in minerals. c Economic Natural Resource Deposit - This is a natural deposit of something that is economically viable to mine‚ refine and sell. Hence the deposit must be big enough to last for a large period of time‚ so that it will make enough money for the

in massive low grade ores and are found in intrusive porphyry formations‚ although many smaller sized but higher grade ores are located in non-porphyry areas. The nation has abundant domestic copper ore reserves but because of many detrimental economic factors much of the copper used by the U.S. industry is imported. Molybdenum ore is profuse and exports of it are high to fulfill the needs of foreign demand. Copper was first used by people around 4000 B.C.
