What is 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 and become concentrated in specific parts such as their shoots and leaves These parts of the plant are …

Fungal Bioleaching. Fungi used: Aspergillus niger and Penicillium simplicissimum Fungal activity: Produce organic acids like gluconic, citric, and oxalic acids from glucose or sucrose.These acids dissolve metals from ores or waste. Process: The fungi convert glucose into organic acids through enzymatic reactions in the cytosol and mitochondria. The acids then …
