Soil phytomining involves using hyperaccumulator plants to extract metals from soil, offering an environmentally friendly and economically viable alternative to traditional mining. This review discusses recent developments in phytomining, focusing on the use of hyperaccumulator plants to extract metals like nickel, cobalt, cadmium, zinc, manganese, selenium, thallium, and noble metals. Hyperaccumulators are plants that can absorb and accumulate metals in their tissues at concentrations exceeding 10,000 mg kg⁻¹ dry weight. These plants can be used to extract metals from soil, which can then be processed for industrial use. The process involves using plants to extract metals from soil, which can then be harvested and processed for metal recovery. The review also discusses the factors influencing metal availability and behavior in soil, including pH, fertilizers, and chelates. The economic viability of phytomining is analyzed, and potential improvements are proposed. The review highlights the importance of further research to enhance the commercial implementation of phytomining and its potential to assist the mining industry. The study concludes that phytomining offers economic and environmental benefits to soil end-users and managers who must cultivate on metal-contaminated soils.Soil phytomining involves using hyperaccumulator plants to extract metals from soil, offering an environmentally friendly and economically viable alternative to traditional mining.
