Using Phytomining to Extract Copper GCSE Chemistry YouTube

Phytomining uses plants to absorb copper ions in the soil. As the plants grow, they absorb the copper ions. The plants rich in copper ions are then burnt and Phytomining is a newly emerged technology in which hyperaccumulator plant species are cultivated on metal-rich medium for commercial metal recovery. Phytomining: a sustainable approach for recovery and

Some of these plants are natural hyperaccumulators, and in others the Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.How are copper compounds extracted by Phytomining?

Highlights. •Processes and opportunities of noble metals (NMs) phytomining were deeply researched. The review presented in this paper link scientific areas as essential elements to form the phytomining chain of NMs. •. Prize and market analysis of NMs to determine the demand side of phytomining. •Summary of Scrap iron can be used to displace the copper from copper sulphate solution. This is desirable as it prevents scrap iron from being sent to landfill. Iron + copper sulphate → copper + iron sulphate. Purifying the copper. Electrolysis is used to purify the copper produced.

One metric ton of soil contains roughly 1.5 grams of germanium. Extracting it with classic mining methods does not pay. Instead, industry collects germanium from the ashes in the exhaust of hardGenerally, the capital cost of a bioleaching operation is approximately 50 percent less than that of conventional smelting operation. This is mainly due to lack of infrastructural costs. The operating costs based on current technology for leaching dumps and ores are between 0.18 USD and 0.22 USD per pound of copper.Mission 2015: Bioleaching MIT Massachusetts Institute of
