The only carbonate materials not consistently recovered by surface or underground mining are shell products that are dredged from parts of coastal waterways. Surface Limestone Mining: The basic elements of surface mining are overburden removal, drilling, blasting and hauling ore to the crushing and processing plant.
Fissionproduct waste is produced when a nuclear fuel, such as U 235, U 233, or Pu 239, is fissioned in a nuclear reactor. (20) In nuclear reactors, the fission of one gram of U 235 produces about 1 gram of fission products. The fission products are, in part, gaseous and, in part, in liquid or solid form, depending upon the fuel used.

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Mining produces mainly tailings (the waste materials left after the valuable ore is separated out) and overburden (the waste materials removed to reach the ore). During the mining process, water within and around the mine is usually contaminated, so treating the mine water before it is discharged back into the environment is a major issue [2].
