Mineral Resources. Almost all Earth materials are used by humans for something. We require metals for making machines, sands and gravels for making roads and buildings, sand for making computer chips, limestone and gypsum for making concrete, clays for making ceramics, gold, silver, copper and aluminum for making electric circuits, and diamonds and corundum .
Magmas richest in SiO 2, such as alkali granite, granite, and tonalite are generally deficient in term such magmas silicic (Sirich) or felsic (contraction of feldspar and silica).Lightcolored minerals dominate felsic rocks, so many geologists use the term felsic to refer to any lightcolored igneous rock, even if the chemical composition is unknown.
The rock is melted in a furnace at 4,000 degrees and the silicon purified even further. The process itself is similar to that used in steel production and is why this molten rock is often referred to as metallurgical silicon. Yet the physical properties are not like those of a metal, they are instead like those of a semiconductor.
First, the material is screened to remove large rocks and boulders. Then a sluice or jig is used to recover the gold. For deposits with high clay content, the rocks are cleaned with a trommel or rotary scrubber to remove contaminants, and then gold recovery can take place. If a significant portion of the gold is fine (<300μm), a high Gforce ...

· The process of transformation of rocks from one form to the other in a cyclic manner is known as the rock cycle. It includes the following processes: Hot lava cools down to form igneous rocks. Igneous rocks are then broken down into small particles which are transported and then deposited This results in the formation of sedimentary rocks.
