Mining industry is one of major economic sources in Democratic Republic of Congo (DR Congo). The mining activities contaminate environments seriously, and it has threatened human beings and 

ecosystems. Especially, the copper-cobalt mine (Cu-Co- U-Zn- Pb -Cd- Ge) in Katanga and Tin ores group(tin- Wolframite - Colombo-tantalite - Beryl -Monazite) in the eastern part as well as other non-enumerated deposits exploited or abandoned in the Democratic Republic of the Congo produce tailings resulting from mining and the concentration discharges containing metallic sulfide minerals exhibit high chemical instability. Exposed to the open air and to the water, they undergo various reactions generate sulfuric acid, allowing the dissolution of the metal elements. This behavior known as Acid mine drainage (AMD) is cause for pollution or contamination of surface water by contamination responsible to acid waters and metal ions such as Fe, Cu, As, etc., by increasing the toxicity of water. This acidity and high toxic metals concentration are harmful to the vegetation, aquatic life and wild life. This paper presents a detailed review of the current state of scientific knowledge, we collected the minimums of the previous data related to the environmental problems of the DRC here of the mining activities whereas the acidic drainage came from storing of the sulfides (Tailings francs), sulfide-poor ores (haldes, selective Tailings) or treatment discharges low in precious metals but rich in sulfides. In the margins of what has been done so we say that the concentration of heavy metals in water, soil, sediment and plant exceeds the normal threshold and this leads to contamination or toxicity in the past. How mining is generating activities in Congo and it is on that basis that the country's economy, it is difficult to stop so the acid mine drainage can be treated and prevented. It would be a future concern for the fight against the production of acid mine drainage.
