Why has phytomining been used to produce gold nickel and copper but is only rarely used to produce zinc and lead?
this question came up in the AQA chemistry text book and in some exam style questions. so the answer is: Phytomining is used to produce gold nickel and copper because they are found in low grade ores the main reason is that gold, nickel and copper are below carbon in the reactivity series which means they are found in native state. (sometimes copper can be found in low grade ores) but phytomining is used rarely to produce zinc and lead is because they are more reactive than gold nickel and copper. this is why phytomining been used to produce gold nickel and copper but is only rarely used to produce zinc and lead.
Can phytomining be used to extract copper?
Yes
What is used in phytomining to remove copper compounds?
Phytomining uses plants to absorb copper compounds from soil through their roots. Once the plants accumulate copper, they are harvested, dried, and burned to produce ash containing concentrated copper, which can then be extracted and purified for use.
What organisms are used in phytomining?
Phytomining uses plants to extract metal ions from soil through their roots. Some common organisms used in phytomining include hyperaccumulating plants such as Arabidopsis halleri, Thlaspi caerulescens, and Alyssum species. These plants have the ability to accumulate high concentrations of metals like nickel, zinc, and copper in their tissues.
What is an advantage of phytomining compared to the traditional method?
One advantage of phytomining is that it is more environmentally friendly compared to traditional mining methods, as it is a less invasive way to extract metals from the soil. Additionally, phytomining can potentially be used to rehabilitate contaminated lands by removing heavy metals through plant uptake.
Where us phytomining being used?
Europe mainly Spain and France
What are the advantages and disadvantages of phytomining?
The advantage of phytomining is that it saves using high grade ores. However the disadvantage is that this is a long process.
What is the difference between bioleaching and phytomining?
Bioleaching is a process where microorganisms are used to extract metals from ores, while phytomining involves using plants to accumulate metals from the soil. In bioleaching, microbes break down the ore to release metals, while in phytomining, plants absorb metals through their roots and then are harvested for metal extraction. Both methods are environmentally friendly alternatives to traditional mining practices.
What metals are in phytomining?
Phytomining primarily targets metals such as nickel, copper, and zinc, which are absorbed by certain hyperaccumulator plants from the soil. These plants accumulate the metals in their tissues, allowing for subsequent harvesting and extraction. Other metals like gold and cobalt can also be recovered through phytomining, depending on the plant species used and the soil composition. This method offers an environmentally friendly alternative to traditional mining techniques.
Is the lead 100 percent lead?
No, pure lead is rarely used in manufacturing due to its softness and poor mechanical properties. Instead, lead is typically used as an additive in alloys, such as lead-acid batteries or solder, where it improves certain properties like machinability or conductivity.
What is used in phytomining to remove copper compound from the land?
Willow has been suggested; please see the first link. For other possibilities please see the second link.
What organisms does phytonmining?
Plants are the organisms used for phytomining. If plants can absorbs the low concentrations of metals in soil, the metals can be concentrated in the biomass of the plants and then extracted from the plant material when harvested.
