Selecting Countertops Based on Environmental Impact | HGTV

Wood. The manufacturing of wood countertops has relatively little environmental impact, because wood doesn''t need to be processed, only sawn, which uses a small amount of energy. Choosing wood countertops that are certified as "sustainably harvested" by the Forest Stewardship Council also helps protect wood as a natural resource.

Plagioclase Feldspar: A group of common rock-forming minerals

What is Plagioclase? "Plagioclase" is the name of a group of feldspar minerals that form a solid solution series ranging from pure albite, Na(AlSi 3 O 8), to pure anorthite, Ca(Al 2 Si 2 O 8).Minerals in this series are a homogenous mixture of albite and anorthite. The names of the minerals in the series are arbitrarily given based upon their relative abundance of albite and anorthite.

Potassium (K)

Potassium in the environment. Most potassium occurs in the Earth''s crust as minerals, such as feldspars and clays. Potassium is leached from these by weathering, which explains why there is quite a lot of this element in the sea (0.75 g/liter). Minerals mined for their potassium are pinkish and sylvite, carnallite and alunite.

Beneficiation and mineral processing of bauxite and feldspar.

Beneficiation and mineral processing of bauxite and feldspar. Bauxite is a sedimentary rock that is rich in alumina, the base for making aluminum. It is generally easy to mine because it is found near the surface of terrain. However, the process for separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
