An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element or elements.. The ore grade, or concentration of an ore ...

Tailings 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.

Reclamation •Reclamation was not required until after FLPMA (Federal Land Policy Management Act) was in place ~1979 •Processing, shipping and removing legacy dump material has in some cases resolved issues with historic mine dumps •Example is the "Hard Cash" project which had a dump eroding into Keating Gulch, removal of that
Reclamation processes for heavy metal contaminated soils are classified into physical, chemical and biological processes (Zhou and Song, 2004, Khalid et al., 2017, Emenike et al., 2018). Different remediation techniques for heavy metal-polluted soil are shown in Fig. 2. Remediation mechanisms are based on two basic principles.
The reclamation plan must provide that reclamation activities, particularly those relating to control of erosion, to the extent feasible, must be conducted simultaneously with mining operations and be initiated at the earliest practicable time after completion or termination of mining on a .

A few iron ore deposits, notably in Chile, are formed from volcanic flows containing significant accumulations of magnetite phenocrysts. Chilean magnetite iron ore deposits within the Atacama Desert have also formed alluvial accumulations of magnetite in streams leading from these volcanic formations.
Some type of reclamation is required regardless of the ultimate use of the processing wastes—whether for retreatment or as sites for pastureland, cropland, airports, golf courses, or industrial or residential development. This paper reports on various methods and approximate costs of achieving stabilization of fine-sized milling wastes.
