What are industrial minerals?

any

rock, mineral, or other naturally occurring

material of economic value,excluding

metals and energy minerals.

The term ‘industrial mineral’ is not defined so strictly as the term ‘ore’ which is

mostly a source of metal, or as that of ‘fossil fuel’ (coal, oil, natural gas), which is

predominantly a source of energy



Kuzvart M, 2007

several types are considered under the term “industrial minerals

and rocks”: raw materials that are used in industry in variously prepared forms as minerals (e.g.,

talc, asbestos, diamond) or rocks (diatomite, bentonite, ochre);

raw materials that serve as a source of non-metallic elements (fluorite for fluorine,

apatite for phosphorus) or their simple compounds (e.g., borates for H3B03 or B203 ); raw materials of non-metallic habit that are source of metals, and also of their com-

pounds employed in other than metallurgical industries (e.g., beryl as a source of BeO,

magnesite of MgO, bauxite or Al-rich laterite as a source of A1203 ; all these three

oxides are refractory materials);

building materials (rocks for aggregate, together with gravel and sand for concrete,

decorative stone and roofing slate, limestone for cement and lime, brickloam).

Harraz, 2014



Non-metallic Minerals



o Highest volume and tonnage

o

low value, but vital commoditieso High total value

o Prices are more stable

o NM are prerequisite raw materials for a wide range of industrial and

domestic products

o Recycling is not much of an issue

o Price of the unit value is so low that transportation becomes a major

issue

o Rarely exported.

o Feasibility study: Often need to find a market before looking for a

nearby deposit

o Depending on their uses, product purity and grain size may becomevery important factors in deciding the suitability and price of the

commodity

o NM support and add value to industrial sectors

o Market demand drives NM supply
