Phytomining : Can plants really grow gold?

Once the plants grow to their maximum height, the soil is then treated with a chemical to make the gold soluble. The plant will then absorb the gold water from the soil and store it within its biomass until it's harvested. As gold behaves differently in plant material, extracting the gold from the plants is not quite as easy as getting them ...
