Older quarrying methods were almost always concerned with obtaining dimension stone for use as building material. Hence, quarrying was limited to areas in which rock of uniform texture and coloration was available. This was usually granite or limestone. All three major types of rock are quarried: igneous, metamorphic, and sedimentary.

Open-pit mining differs from quarrying (with the possible exception of iron ore) in that the valuable mineral constitutes only a small proportion of the total tonnage of rock produced. In quarrying, the rock itself is the valuable commodity, with virtually all of the raw rock that is won being processed (often only by crushing and screening) to ...

The most familiar type of oxidation is when iron reacts with oxygen to create rust (figure 8). Minerals that are rich in iron break down as the iron oxidizes and forms new compounds. Iron oxide produces the red color in soils. Figure 8. When iron rich minerals oxidize, they produce the familiar red color found in rust.
