Alternative Methods of Extracting Metals (AQA GCSE Chemistry Combined Science): Flashcards

Uses plants to extract $\text{Cu}$ from low-grade ores

Uses bacteria to extract $\text{Cu}$ ions from low-grade ores

Depletion concerns about high-grade ore reserves

Excellent electrical conductivity

Brass and bronze

Finite natural resource

Minerals, including copper compounds, from soil

Ash with higher concentration of $\text{Cu}$ compounds

Less harmful to environment, reduces carbon emissions

Slow/time-consuming process

Leachate (solution rich in $\text{Cu}$ ions)

Produces no carbon emissions

Time-intensive/slow process

Attracted to negative electrode

More reactive than copper
