Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. A Gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver. The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is.
In auriferous Pyrite The mineral pyrite, or iron pyrite, also known as fool’s gold, is an iron sulfide with the chemical formula FeS? (iron(II) disulfide). Pyrite is considered the most common of the sulfide minerals. en.wikipedia.org quartz lodes the minerals most commonly associated with gold are iron and copper pyrites, zinc blende, galena, and tetradymite. Tellurides of gold are very widely distributed. Other minerals occurring with gold are tourmaline, calcite Calcite Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as “calcite”. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite.

What are minerals How are minerals important to us Class 7
Minerals are natural substances that acquire certain physical properties and a certain type of composition. Minerals are very useful for mankind. Some minerals such as coal, gas and oil are used as fuel. They are also used in all industries.

The whole body perceives these metals as toxins.
