Phytomining is the sustainable makeover the mining industry needs

Aug 6, 2021Phytomining, the process of producing metal by growing plants, is not new, but many are unaware of its untapped potential. There are about 700 plants in the world that suck up metal from the soil around them at a high rate. These metals, like nickel, zinc, cobalt, and even gold, are harvested when the plants are burned, resulting in "bio-ore.".

Phytomining Pros and Cons for Environment and Economy

Phytomining describes the production of a metal crop by using high-biomass plants, which are plants that produce energy or a usable resource when burnt. Phytominers cultivate crops of a specific plant species with high concentrations of a desired metal, harvest the plant and deliver it to a furnace to burn and gather its bio-ore.
