How copper is extracted by phytomining and bioleaching?
Bioleaching uses bacterial microorganisms to extract precious metals, such as gold, from ore in which it is embedded. As an alternative to smelting or roasting, miners use bioleaching when there are lower concentrations of metal in ore and they need an efficient, environmentally responsible method. The bacteria feeds on nutrients in minerals, thereby separating the metal that leaves the organism's system; then the metal can be collected in a solution. Bioleaching works because of how special microorganisms act on mineral deposits. They are a catalyst to speed up natural processes inside ore. The bacteria uses a chemical reaction called oxidation to turn metal sulphide crystals into sulfates and pure metals. These constituent parts of ore are separated into valuable metal and leftover sulphur and other acidic chemicals. Eventually, enough material builds up in the waste solution to filter and concentrate it into metal. For some types of metal, such as copper, bioleaching is not always economically feasible or fast enough, even with its low cost. However, in certain areas of the world or with other metals, this simple, effective, and low cost method offers a smart choice. For example, developing countries often do not have the infrastructure or capital investment to begin smelting, yet their land contains enough ore that its extraction can significantly improve their national economy. One day we may use bioleaching to mine other metals, such as zinc and nickel, on the Moon.
I have to make a storyboard of six to eight boxes explaining the processes of bioleaching. I am only in year nine so what is bioleaching in simple terms?
Bioleaching is a process where bacteria or fungi are used to extract metals from ores. These microorganisms break down the ore and release the desired metals. Bioleaching is an environmentally friendly and cost-effective way of extracting metals.
Why would an increase in bioleaching not happen?
An increase in bioleaching may not happen due to limited availability of suitable bacteria or microbes required for the process. Additionally, unfavorable environmental conditions such as extreme temperatures or pH levels can also hinder the growth and activity of bioleaching microorganisms. Lastly, regulatory restrictions, high costs, or lack of infrastructure to support bioleaching operations could also prevent an increase in its implementation.
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.
What metals are extracted using phytomining?
Metals such as nickel, copper, and cobalt are commonly extracted using phytomining. This process involves growing hyperaccumulating plants that can absorb high levels of metals from the soil through their roots. Once the plants are harvested, the metal-rich biomass is collected and processed to extract the valuable metals.
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.
How do you extract copper from a low grade ore?
Copper can be extracted from low-grade ore through a process called bioleaching, where microorganisms help break down the ore to release the copper. This method is more environmentally friendly and cost-effective compared to traditional methods like smelting. The extracted copper can then be further purified and processed into usable forms.
What are the disadvantages of bioleaching?
is not cheap
Is phytomining good?
nope
What are advantages of phytomining?
its good

What is ment by phytomining?
Phytomining basically means in order to reduce metal contamination and that the metal is economically expenisve or useful in some way to extract it would amend their soil with phytoaccumulating plants.
