Analysis of the mobilization of solid loads and heavy metals in runoff
The metal concentrations do not correlate with the dissolved solids, which would indicate that they generally appear in particulate form. This behaviour coincides with the highest correlations of the SS with all the metals (greater than 0.9, between 0.9 and 0.85), less than Ni (0.73) with Cu (0.59) and Zn (0.76), which show anomalous behaviour.

A total of 64 hard rock quarries are located in the basin which together extracts about 6.75 million t y −1 of rocks/rock products for different purposes. An assessment of the impacts of quarrying using the rapid impact assessment matrix (RIAM) reveals marginal, short-term positive impacts in economic-operational components but major negative impacts on all the other environmental components.

Solid Rock to Building Block
Students continue their pyramid building journey, acting as engineers to determine the appropriate wedge tool to best extract rock from a quarry and cut into pyramid blocks. Using sample materials (wax, soap, clay, foam) representing rock types that might be found in a quarry, they test a variety of wedges made from different materials and with different degrees of sharpness to determine which

The science of metals
Producing large quantities of a metal like iron, aluminum, or copper therefore involves two distinct operations: extracting an ore (a deposit consisting usually of a huge amount of useless rock and smaller amounts of useful metals) from a mine or quarry and then refining the ore to get the metals away from their oxides (or other compounds) into the pure form that we need.

Heavy metal content and toxicity of mine and quarry soils | SpringerLink
The metal concentrations in the quarry soils from the different areas are highly variable, especially Cr pseudo-total contents (Table 2); this is related to the occurrence of metal ores, whose accumulations depend on natural and anthropogenic factors, like historical quarrying, as well as on how the waste was deposited, among other factors.

Recycling in Mining –Greener Possibilities
Waste Rock Reclamation The most prevalent reclamation of waste rock or for that matter any coarse-grained mining wastes from coal and metal mining are as building and construction materials. These wastes are used as aggregates in embankment, dam, road, pavement, foundation and building construction and equally finding applications as feedstock for the production of cement and concrete.
