how are minerals processed for human use

Mining and Mineral Use | Earth Science. Then the minerals are separated out of the ore. A few methods for extracting ore are: heap leaching: the addition of chemicals, such as cyanide or acid, to remove ore. flotation: the addition of a compound that attaches to the valuable mineral and floats. smelting: roasting rock, causing it to segregate into layers so the mineral can be …

25.2 Extracting ores | Mining of mineral resources | Siyavula

Rocks with large concentrations of minerals, are called ores. Mining depends on finding good quality ore, preferably within a small area. The next step is to get the rocks which contain the mineral out of the ground. Once the ore is on the surface, the process of getting the mineral you want out of the rock can start.

How did minerals form in our earth? - UCSB Science Line

Minerals can form in several ways. They can form when magma crystallizes. They can also form due to weathering of existing rocks, or they can form by precipitating dissolved chemicals from water. One other way minerals can form is during the process of "metamorphosis" -- when rocks of one type gradually get transformed into another kind of rock.
