Africans are blessed with a lot of minerals that if this resources are gainfully used for benefit of their citizens, this God given resources would add colours to Africans. Countries in Africans like Nigeria, Serial Leone, Ghana, kenya, south Africa and lots more you will a lot of natural resources either misused or abandon by government and even if they see need to use them, is either abused or mismanaged. Petrol in Nigeria till today is been refined outside country and still import back to Nigeria on a high price, lots of minerals like coals, salt, kerosene, gas, petroleum and so on but no appropriate handling of this resources, so even the citizens can not benefit from it. If Africa can make use of their resources well, they will be more independent, free from indebtedness and indirect colonial system of other countries.
Problem is lack of knowledge. Most areas in Africa were deprived of education. Minerals will just be a potential but won't be too beneficial if people cannot utilize it in such way their economy would make use of it on global trade of goods. Another indeed is resources such as tools and equipments for them to make use of those minerals. Usually, on third world countries, foreign countries are ones who make use or take advantage of the circumstance, they become the capitalists in that country. Same thing happens in my country wherein most of the big companies are owned by foreign people. Even with agricultural movements, locals are being used as workforce.
