Methods of Extracting Copper from Low Grade Ores: Bioleaching and Phytomining

The video discusses the extraction of copper from low-grade ores using two methods: bioleaching and phytomining. Bioleaching involves bacteria that produce a copper ion solution, which is then processed with scrap iron and electrolysis. Phytomining uses plants to absorb copper ions, which are then extracted from the ash after burning the plants. Both methods are environmentally friendly but produce small quantities of metal over a long time.
