in an empirical approach to the search for new deposits. The ore and associated minerals in ore deposits comprise rocks that may be significantly different in their physical and chemical properties from the enclosing host rocks. Distinct physical properties such as density, magnetic characteristics, radiometric signatures and electrical properties

In another common method of classification, ore minerals are divided into hypogene (also termed primary) deposits and supergene (also known as secondary) deposits. The secondary deposits are formed as alteration products of primary deposits through weathering and related processes. An ore deposit may be either of igneous or of sedimentary origin.

Most ore minerals are sulfides. In the Dana classification, sulfides are given the general formula AmXn, where A consists of the metallic elements principally and less frequently the semimetals As, Sb, and Bi. The classification of the large number of sulfide minerals is based upon decreasing A:X rations.

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 (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level
