Welcome to Puyallup Valley Gem Mineral Club The Puyallup Valley Gem Mineral Club exists to foster, promote and develop the interest of its members in geology and the earth sciences, mineralogy, gemology and similar subjects. We pursue these subjects as a hobby for social, recreational and educational purposes.
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

Mining is a challenging business in which competitive pressures demand safe, reliable, and efficient solutions. With an everconstant need for raw materials, the mining industry requires established, reliable processes that optimize production while reducing maintenance costs.
Quartz responds far slowly to the chemical attack than olivine or pyroxene. The arrangement of minerals according to the susceptibility to chemical weathering is called weathering series. The minerals in the weathering series are essentially in the same order as Bowen's reaction series, the order in which minerals crystallize from molten magma.
EdTalks: MINERALS WORTH TALKING ABOUT. Join our mining history expert and Collections Manager, Ed Raines, for a fascinating lecture series on the geology and mining history of Colorado. Watch past lectures on the Museum Facebook page or here: EdTalks Archive. The next EdTalks lecture series, will be scheduled shortly. Please check back soon!
In the case of the igneous rock minerals described in Bowen's Reaction Series, the higher temperature minerals (such as olivine, pyroxene, etc.), when exposed at the surface, will be farthest from their comfort zone, and will therefore chemically weather at a faster rate.
Garnet often occurs as an accessory mineral in igneous rocks such as granite. Many people are familiar with almandine garnet because it is sometimes seen as dark red crystals in the igneous rocks used as granite countertops. Spessartine is an orange garnet found as crystals in granite pegmatites.
Mining Matters is a charitable organization dedicated to bringing knowledge and awareness about Canada's geology and mineral resources to students, educators and the public. The organization provides current information about rocks, minerals, metals, mining and the diverse career opportunities available in the minerals industry.

The common rockforming minerals form in a regular sequence, with olivine and calciumrich plagioclase at the top of the list, crystallizing at temperatures some 500600ºC higher than quartz, which is at the bottom of the list.

As the temperature continues to fall, these two series merge, and more minerals crystallize in this order: Alkali feldspar, muscovite, and quartz. A minor reaction series involves the spinel group of minerals: chromite, magnetite, ilmenite, and titanite.

The common rock forming silicate minerals (except quartz) weather by hydrolysis to form: 1) clay minerals 2) soluble silica 3) metal cations. Cations are positively charged ions; ions are charged atoms with too many or too few electrons.
If an igneous rock is heated, which mineral melts first according to Bowen's reaction series? Ironrich minerals will form in a cooling magma and leave the remaining melt with a more silicic composition.
