What are the two main types of metal extraction?
extraction of metals – introduction. This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis.

What method is used to extract sodium from its ore?
Electrolysis
Is Coke used in metal extraction?
Answer:The role of coke in the extraction of iron from its oxides is that it reduces the iron oxide to molten iron metal. Coke also when burnt in the blast furnace, supplies the heat required for carrying out the extraction of iron from its oxide.
What is coke pushing?
The pushing process involves a machine that uses a “ram” to guide the coke out of the oven. The ram guides the coke into a railroad car that is called the “quench car.”

What conditions does Cocoa need to grow?
Cocoa trees don’t just grow anywhere. In fact, they need a hot and humid climate to flourish. Cocoa evolved in the Amazonian forests as an under-storey crop, so they like to be under forest trees or other crops where there is shelter from direct light.
