Metal Extractions

Question 1

What are the two different types of displacement separation techniques

Answer 1

1) displacement with a more reactive metal

2) displacement with carbon

Question 2

What is the electrolysis separation technique

Answer 2

Electrolysis using energy - for pure and very reactive metals

Question 3

What is the copper separation technique

Answer 3

Copper from low grade ores

Phytomining= with plants
Bioleaching = with bacteria

Both still require electrolysis but no extraction to make them pure
