the kind of mining waste and its share in the total waste stream in the different countries highly depend on their natural resources, economic value of a mineral and market demand, and therefore ranges from almost none to the predominant proportion. unfortunately, due to the scarce statistical data, the information on the mining waste generated waste occurs in several stages of the mining process and throughout the life of the mine, from the first exploration drilling project to the last processed material before mine closure. several types of waste are generated in a mine, but three types stand out with the largest volume: waste rock, tailings and mine
