Africa is shaped like a gun, and Congo is the trigger. If that explosive trigger bursts, it's the whole Africa that will explode said Frantz Fanon.
Congo is among the richest country in the world, we can even say that it is the richest country in the world.
Here is some of them
Diamond is used to make jewelry like rings, watches and necklaces
Copper is used to make for electrical generators and motors, electrical wiring, copper is used in motor vehicle, radiators, air-conditioners, home heating systems and so forth
Uranium is a principal fuel for nuclear reactors and the main raw material for nuclear weapon, it is again in kinetic energy penetrators and armor plating,… (Institute for energy and environmental research)
Gold is also used jewelry and is much again used in electrical field.
Congo has the 80% of worldwide Coltan reserve
The ore Coltan is just one of many minerals over which there is a civil war going on. When it comes to its mineral reserves (particularly diamonds, coltan, cassiterite, tin, and copper) the Democratic Republic of the Congo is one of the richest countries in the world. And Coltan is its Gold. Out of the ore you obtain the rare metal Tantalum. Without it, the modern world wouldn’t be the same: Tantalum is used in cameras, game consoles, laptops, flat-screen TV’s, nuclear reactors as well as our mobile phones. Since all of these gadgets are produced in huge quantities, the demand for Coltan constantly ascends. And the worst part about this: there is no real alternative for it.
This is what made Congo a poor country, the counrty is plundered and the population remain poor
In the past ten year, millions of people have died; villages have been (and still are) raided & families have been massacred. The money from the Coltan sale is often immediately spent on new weapons; it’s a vicious circle.
