Why can you use phytomining when it would be too expensive to extract metals in other ways?

I had this question set too. I wasn't sure but I think it's because it is a natural way of extracting metals because the plants naturally absorb the chemicals from the ground. Also because the technology used to create the metals are simple to use.

What is expensive alloy or aluminum?
alloys because they are a combination of metals for example steel is acombination of iron and other metals
Which metal ore do you m ine to extract steel?
No ore contains steel. However, IRON ore, such as taconite, produces iron. When alloyed with other metals and carbon, it becomes steel.
Are alkali metals and alkaline earth metals always found combined in nature?
They react easily. They combine with other elements to complete/fill their outer shell.
Why are other metals added to stanless steel?
why are other metals added to stainless steel
Which metal forms an amalgam which other metals?
Mercury forms amalgams with other metals.
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 type of chemical reaction is used to extract metals from their naturallly occurring compounds like oxides or chlorides?
For example reduction with hydrogen and carbon from oxides, reduction with other metals from chlorides, etc.
Why can't you extract lead from lead oxide but you can with mercury and mercury oxide?
actually you can still extract lead from lead oxide, but you need to do this experiment with carbon or other reducing agent e.g. hydrogen and with a high temperature Celsius. But the reason that you can extract the mercury from the mercury oxides exactly is the higher reactivity of the lead. higher the reactivity means more difficult to extract the metals from the ore. so it is possible for lead to extract it from the lead oxide
What metal element used for making jewellery?
Many different metals are used. Jewelry is often based on certain expensive metals such as gold, platinum, or silver, but other metals are used as well.
Why are there more metals available now than there was 200 years ago?
There are more metals available now than there was 200 years ago. This is because more metals have been harvested.The reason is because of advancements and increased accuracy in technology. Other metals became more readily available overtime as it became possible to extract metals from their ores. These technologies were not available 200 years ago.
What are the disadvantages of silver?
It's expensive because it is quite scarce, it tarnishes, and it melts earlier and is less strong than some other metals.
Which metal ore do you m ine to extract steel?
No ore contains steel. However, IRON ore, such as taconite, produces iron. When alloyed with other metals and carbon, it becomes steel.
Why do use iron in making cooking utensils?
Because most of the other metals are expensive. To make it sure that it is a good quality and it can't be melt from heat.
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 is the uses of tin cars?
Tin is only used to make toy cars.Pure tin is an expensive metal and is used just to coat other metals to prevent corrision.
Why isn't pure aluminum used to make large objects?
It is. But adding other metals to it to create an alloy gives you a stronger material. It can also be expensive in large quantities.
