THE CHEMICAL PROPERTIES OF MINERALS. Atoms, Molecules, and Elements. Every substance on earth is made of atoms, the building blocks of all matter. There are all different types of atoms, and each type of atom is classified as an will bond together to form molecules, which are organized agglomerations of different types of atoms..

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the lowgrade phosphate ore is, hence, of great necessity.

Beryllium can also cause allergic reactions with people that are hypersensitive to this chemical. These reactions can be very heavy and they can even cause a person to be seriously ill, a condition known as Chronic Beryllium Disease (CBD). The symptoms are weakness, tiredness and breathing problems. Some people that suffer from CBD will develop anorexia and blueness of hands and feet

Minerals have a fixed chemical makeup and a definite crystal structure (its atoms are arranged in orderly patterns). Therefore, a sample of a particular mineral will have essentially the same composition no matter where it is from—Earth, the Moon, or beyond. Properties such as crystal shape, color, hardness, density, and luster distinguish minerals from each other. The study of the

Mineral associations and the chemical and physical characteristics of the particular ore will affect in one way or another the results that can be secured. Each ore presents its own individual problem, but the experience gained from the investigation or treatment of a similar ore will indicate likely methods to follow and a comprehensive ore test will show the results that can be expected.

1. Rockforming minerals are the few dozen abundant minerals that make up most of Earth''s crust. Economic minerals are the less abundant minerals that society uses extensively in the manufacture of products. Some rockforming minerals can also be considered economic minerals when present in the proper quantity and geologic setting. 2. Oxygen

Chemical properties are any of the properties of matter that can be observed and measured only by performing a chemical change or chemical reaction. Chemical properties cannot be determined by touching or viewing a sample; the structure of the sample must be altered for the chemical properties to become apparent.

Mineral Mineral Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (, halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level
