Opencast mining has been associated with a change in land use and land cover of a region. The process of clearing trees and vegetation in preparation for mineral excavation has huge impacts on prevailing ecosystems. In eco-sensitive areas like forests and hilly regions, loss of native and unique species is also coupled with h…

Flotation is much more efficient than gravity separation and older wastes contain more residual metals than modern tailings. T h e objectives of this study were to establish whether calcareous mine wastes could replace quarried limestone for soil and to confirm that their heavy metal contents (Cd, P b and Zn) do not preclude this use.

In this work the adsorption and immobilization of copper ions of four different Technosols constructed with wastes were tested. These soils were made from mixtures of limestone wastes, organic matter, sand, and bentonite. The methods used were "batch" and columns experiments, where the soils were in contact with a Copper (Cu) rich solution for 24 h …

Furthermore, the mining areas can also be inhabited by some exotic species, such as Monty et al. (2019), who recorded the significant invasion of alien plants on limestone quarry wastes, which resulted in indigenous species habitat loss. Additionally, limestone quarries can cause soil erosion and dereliction of mined sites (Langer, 2001). A ...
