The main object of ore reserve classification is to assess the reliability of an ore reserve estimate. Because traditional classification schemes fail to provide a means of calculating this reliability, the terms 'proven', 'probable' and 'possible' ore were introduced as an attempt to qualify it.Geostatistics, on its part, allows the quantification of the precision of any ore estimate and thus ...

Mineral Classification. The Dana System Mineral classification can be an organizational nightmare. With over 3,000 different types of minerals a system is needed to make sense of them all. Mineralogists group minerals into families based on their chemical composition. There are different grouping systems in use but the Dana system is the most commonly used.

The minerals of the oxide class are those which contain oxygen bonded to one or more metallic elements. Hydroxides are compounds of a metallic element and water or the hydroxyl anion (OH)-. The oxide minerals tend to be relatively hard, and some of them may be used as gemstones. Many provide economically important metal ores.

The ore deposit can also be classified basing on the formation time relationship with the host rock into; a) Epigenetic mineral deposit b) Syngenetic mineral deposit Epigenetic mineral deposit Formed much later than the rocks which enclose it.

The term ore is often used loosely to include such nonmetallic minerals as fluorite and gypsum. The broader term, mineral deposits, includes, in addition to metalliferous minerals, any other useful minerals or rocks ( Fig. 1 ). Minerals of little or no value which occur with ore minerals are called gangue.

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.
