Answer :
The empire of Ghana trade its gold for salt.
Ghana is a country in West Africa which traded its gold for salt. Hence, the trade was known as gold-salt trade.
What was the gold-salt trade?
The Gold-salt trade via the Sahara Desert has been going on for many centuries. The gold-salt trade was an exchange of gold for salt between West African countries and Mediterranean economies during the Middle Ages.
West African kingdoms, such as the Soninke empire of Ghana and the empire of Mali were rich in gold but they lacked salt. People wanted gold for its beauty, but they needed salt in their diets to survive. Salt, which could be used to preserve food, also made bland food tasty. These qualities made salt very valuable.
So, Ghana was chiefly bartering gold, ivory, and slaves to Mediterranean economies in exchange for luxury goods and ultimately salt from the desert.
