BBC - GCSE Bitesize: The future of copperPhytomining, bioleaching and scrap iron. Some plants absorb copper compounds through their roots. They concentrate these compounds as a result of this. The plants can be burned to produce an ash that contains the copper compounds. This method of extraction is called phytomining. Some bacteria absorb copper.advantages and disadvantages of phytomining bioleaching and recycling,Exampro GCSE Chemistry - Mount Grace SchoolQ6. Copper is found in the Earth's crust as an ore containing copper sulfide. Large areas of land, where this ore was once quarried, are contaminated with low percentages of copper sulfide. Copper would be too expensive to extract from this contaminated land using the traditional method of quarrying and then heating in a.
What are the social, economic and environmental impacts of exploiting metal ores (mineral extraction), of using metals and of recycling metals – economic, . It doesn't matter whether you are mining and processing iron ore or line, many of the advantages and disadvantages are common to these operations.
The Extraction of Copper by Thermal Decomposition, Bioleaching and Phytomining.
As mentioned in the e-book, aluminum is the most commonly recycled nonferrous metal. (Ferrous is Latin for iron, so a nonferrous metal is a metal which does not contain iron.) Aluminum is recycled because it takes a lot less energy to recycle aluminum than it takes to extract aluminum from bauxite ore, which requires.
Bioleaching is the extraction of metals from their ores through the use of living organisms. This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel,.
The statements below cover the advantages and disadvantages of bioleaching and phytomining. Bioleaching. Advantages: • Simpler process than smelting which requires fewer expert staff to operate, reducing costs. • Produces less sulphur dioxide emissions than smelting. • Used to extract copper from low grade ores (ores.
Dec 19, 2016 . It seems that no clean energy discussion is complete without everybody's favorite pastime: recycling. In its simplest definition, recycling is converting waste product into reusable material. Instead of being taken to a landfill to sit and rot the Earth for years to come, it gets singled out and repurposed for.
As part of their work on metals, GCSE chemistry students will look at some of the problems that arise in their extraction from ores. As with most things, there is a financial cost, but there's also an environmental one. Revise what you learned in Year 10 and Year 11 by playing this interactive quiz.

could be recycled by melting and making them into new plastic products. • could be burned to release energy. Use the ... Bioleaching uses bacteria. The bacteria produce a solution of copper sulfate. .. (2 marks). 5 (c) (ii) Use this information to suggest one disadvantage of phytomining compared to the traditional method.
Feb 10, 2010 . Abstract: - The basic disadvantages of classical methods for Re recovery from ores and concentrates were shown. An alternative method by phytoextraction of Re from ore dressing soils was proposed. The content of Re in phytoconcentrates of lucerne (46 586 g Re/t dry mass) and clover (35 090 g Re/t dry.

(c) In the UK, we use about 1.8 billion steel cans every year but only 25% are recycled. Used steel cans are worth . steel by recycling used cans saves 75% of the energy that would be needed to produce steel from iron ore. .. (ii) Use this information to suggest one disadvantage of phytomining compared to the traditional.
Ores are rocks that contain minerals and metals. But how do we get them out? By extraction of course! There are a few methods which GCSE chemistry students need to be aware of. Do you know them? Try this fun quiz, written by teachers especially to help Year 10 and Year 11 students revise the topic.
