Reuse of iron ore mineral wastes in civil engineering,

Stripping ratios of the deposits in strip-mined quarries is often one of the steps producing the most waste during ore extraction operations. The physical and chemical composition of the waste varies considerably according to the substance mined and the nature ofMining Waste | Special Wastes | Wastes | US EPA,The extraction and beneficiation of minerals generates large quantities of waste. Mineral processing operations generally follow beneficiation and include techniques that often change the chemical composition the physical structure of the ore or mineral. Examples of mineral processing techniques include smelting, electrolytic refining, and acid,Tailings - Wikipedia,Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
