Phytomining, the process in which certain plant species can absorb metals from previously mined land, could be a way to extract value out of mine waste. Copied. A world where Mother Nature extracts in-demand metals from the ground in cost-effective and sustainable ways is being touted as a major value adder to conventional mining methods.

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.
