COPPER 😔😔

Question 1

Ways to obtain copper from ores

Answer 1

• add sulfureux acid to produce copper sulphate then extract the copper from that
• smelting- heating in a furnace to produce impure copper

Question 2

What’s coppers problem

Answer 2

It’s finite and running out

Question 3

What happens after smelting

Answer 3

• impure copper produced in smelting is made into pure in electrolysis

Question 4

What are the problems with extracting copper from copper rich ores

Answer 4

• it takes a lot of energy
• costs a lot
• damages environment

Question 5

Other ways to extract copper from ores

Answer 5

• copper solutions extracted by electrolysis to be pure
• displacement using scrap ions

Question 6

Two ways to extract copper from low grade ores

Answer 6

• bioleaching
• phytomining

Question 7

Explain the process of phytoming

Answer 7

• plants are grown on soil containing low grade copper ores
• plants are burnt
• ashes are used to extract copper from their copper compound
• the copper ions in the compound can be added to sulphuric acid which makes a solution of copper sulphate
• then that is displaced by scrap irons

Question 8

Explain process of bioleaching

Answer 8

• bacteria feeds on low grade metal ores
• lecheate- a solution of copper ions- can be obtained
• scrap iron/ electrolysis can get copper from this
