GCSE CHEMISTRY - Extraction of Copper - …
Copper is sometimes found as native metal. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.

Advantages & Disadvantages of Phytomining | …
Phytominings success is subject to the forces of nature. Unlike traditional excavation, phytomining is dependent on growing conditions such as the weather, altitude and soil quality. A bad growing season could wipe out an entire crop of metal-producing plants, and if global climate change alters weather patterns, the risks associated with establishing a long-term phytomining industry in an area …
Phytomining - ScienceDirect
Phytomining is the production of a `crop of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced. Pioneering experiments in this field might lead to a `green alternative to existing, environmentally destructive, opencast mining practices. Phytomining for a range of ...
