Bioleaching Phytomining Edexcel GCSE Chemistry . Phytomining. This process takes advantage of how some plants absorb metals through their roots The plants are grown in areas known to contain metals of interest in the soil As the plants grow the metals are taken up through the plants vascular system ande concentrated in specific parts such as their shoots and leaves …
Phytomining describes the exploitation of sub-economic ore bodies using plants. Would-be phytominers grow a crop of a metal-hyperaccumulating plant species, harvest the biomass and burn it to produce a bio-ore. The first phytomining experiments were carried out by Larry Nicks and Michael Chambers at the US Bureau of Mines, Reno, Nevada using ...
Like phytomining, bioleaching is a useful method for extracting metals from low-grade ores. This is particularly important for copper, where high-grade ores are increasingly rare. It also uses less energy than smelting. However, some of the chemicals produced in the process are harmful, and the process is relatively slow and expensive.
The process is more environmentally friendly than traditional extraction methods. Less profit is made from bioleaching which means it is less appealing to buisness men and women. Bioleaching can extract metals from ores that are too poor for other technologies which means less waste. Toxic chemicals are also sometimes produced in this process.
