• Metal extraction can be done using more reactive metals to displace the less reactive metal from its oxide

• The thermite process is used to extract iron from iron oxide on a small scale

• This reaction releases so much heat that it is able to melt iron which has a melting point of 1,538 ° C

• Metal extraction in the industry is done using two main methods, namely heating of oxide logs with carbon (cheap and easy) and electrolysis of molten metal compounds

Methods of extracting some types of metals:

Iron extraction:

• A mixture of iron ore, limestone, and carbon (coke charcoal) is put in a blast furnace and heated at 1,900 ° C

• The reaction takes place and iron is extracted as molten iron

Tin extraction:

• Tin ore will be processed first to remove impurities

• A mixture of tin, limestone, and carbon (coke charcoal) is placed in a blast furnace and heated to 1,350 ° C

• The reaction takes place and tin is extracted as a tin melt

Adverse effects of mining activities:

• The destruction of the environment and ecosystems is disturbed

• Soil erosion and landslides occur

• Air and noise pollution
