phytomining and bleaching

• What are the two methods used to extract copper from low-grade ores?

  Phyto mining and bio leaching
• Why is copper considered a vital metal?

  It is used in electronic equipment
• What does the term 'economical' mean in the context of metal extraction?

  Cost-effective
• What is the problem with copper ores currently?

  Copper ores are becoming scarce
• What are low-grade ores?

  Ores that contain a small amount of copper
• How does phyto mining work?

  Plants absorb metal compounds and concentrate them
• What happens to plants in phyto mining after they absorb metal compounds?

  They are harvested and burned
• What is produced at the end of phyto mining?

  Ash with a high concentration of metal compound
• What is bio leaching?

  Using bacteria to extract metals from ores
• What do bacteria produce in bio leaching?

  A solution called leachate
• What does leachate contain?

  A metal compound that we want
• How is copper extracted from its compounds?

  By displacing it using iron
• Why is scrap iron used for displacing copper?

  It is cheap
• What is another method to extract copper besides displacement?

  Electrolysis
• What are the key points about phyto mining and bio leaching?

  • Economically extract metals from low-grade ores
  • Do not involve large-scale mining operations

• What is the worldwide demand for metals doing?

  It is growing
• How do phyto mining and bio leaching differ from traditional mining methods?

  They do not require large-scale digging
• What is the main use of copper in modern technology?

  In electronic equipment
• Why is it important to learn about phyto mining and bio leaching?

  They help extract metals from limited resources
• What is the role of bacteria in bio leaching?

  They carry out chemical reactions
