Which sequence shows the correct order for Phyto-mining?

• row plants - metal builds up in leaves - harvest plants - extract metal using electrolysis

• metal builds up in ground - harvest plants - extract metal using electrolysis - grow plants

• grow plants - harvest plants - extract using electrolysis - metal builds up in soil

• grow plants - metal builds up in soil - harvest plants - extract metal from soil

Which series shows the correct order for bioleaching?

• bacteria absorb metal compounds - convert to metal - purified by electrolysis - solution added to extract metals

• bacteria absorb metal compounds - solution added to extract metals - purified by electrolysis - converted to pure metal

• bacteria absorb metal compounds - convert to metal - solution added to extract metals - purified by neutralisation

• bacteria absorb metal compounds - convert to metal - solution added to extract metals - purified by electrolysis

Phyto-mining and bioleaching have advantages over traditional extraction methods. Which of these is NOT an advantage of bioleaching and phyto-mining?

• less damaging to the environment

• less overall energy used in the extraction

• less is produced than traditional mining
