11. What is Applied Mineralogy?
21 November Prof. Dr. H.Z. Harraz Presentation Applied Mineralogy, Introduction 11
Applied Mineralogy is the science aiming:
i) to study problems related to the use of mineral resources at the
service of mankind and
ii) to study the impact of human activities on the mineral world.
Of particular interest are
those problems related to the exploration, exploitation and processing of mineral
resources on one hand and
the problems related to health, mineral waste disposal and geomaterials alteration on
the other hand.
In all these problems, applied mineralogy is characterized by a mineral-based approach.
By mineralogical approach, we mean a description of any material in terms of mineral phases.
This deals with the identification of :
 the nature of mineral phases,
 the determination of their grain size, shape and structural arrangement
(texture analysis).
As a corollary, applied mineralogy is also concerned with the development
of instruments and sensing technologies that allow to quantify such properties at lab
or process level.
Because applied mineralogy mostly relates to a microscopical analysis of large-scale problems it is
essential that representatively issues be discussed. Sampling theory, statistical process control and
upscaling of physical properties are of major interest to this research field.

12. Definition:
21 November Prof. Dr. H.Z. Harraz Presentation Applied Mineralogy, Introduction 12
 Applied mineralogy is mineralogical materials science…………
 It concentrates on anorganic non-metal materials and comprises all
aspects of their analysis, sampling, preparation, synthesis, property
determination and evaluation.
 Applied mineralogy overlaps with the appropriate sections of other
physic-chemical, technical and life sciences.
Identification of mineral resources
Processing of mineral resources
Properties of use of mineral materials
Development of instrumentation
Environmental incidence of mineral materials
Cultural heritage

Applied mineralogy and
identification of mineral resources
Mineralogy takes its
roots from the
description of naturally
occurring phases.
In that sense, applied
mineralogy is
particularly concerned
with those minerals
occurring in nature and
having an impact on
human activities
(economic mineralogy,
environmental
mineralogy,…).
Applied mineralogy and
processing of mineral resources
 An important topic in applied
mineralogy is the follow up of
minerals in industrial processes.
 This includes the use of
mineralogical / petrographical tools
in analyzing :
 Sub-products from mineral
processing circuits.
 Products and wastes/slags
from hydro- or pyro-
metallurgical processes.
 Fired mineral materials :
glass, ceramics, refractories,
clinker, bricks, …
 Hydrated mineral materials :
cement, plaster, …
 Cut and polished minerals :
gems, ornamental stone ,…

14. 21 November Prof. Dr. H.Z. Harraz Presentation Applied Mineralogy, Introduction 14
Applied mineralogy and properties of
use of mineral materials
 Both natural and synthetic minerals
are used in many products as fillers,
extenders, hydraulic bonding agents,
etc.
 Applied mineralogy is concerned with
the study of relationships between
the mineral/microscopical properties
and the physical properties of such
materials :
 Optical properties
 Abrasive properties
 Mechanical (compression,
tension,…) properties of building
materials
 Mechanical (compression,
tension,…) properties of
composite materials
 Alteration of building materials
(ornamental stones, concrete,..)
Applied mineralogy and environmental
incidence of mineral materials
At each step of the industrial cycle (extraction,
production, use and destruction of mineral
materials) wastes are produced. These wastes
enter the environment and interact with the
biosphere, the atmosphere, the hydrosphere
and impact on earth sustainability.
Applied mineralogy is concerned with studies of
:
 Minerals synthetized within or entering the
human body.
 Studies of emission dust and nanoparticles
emitted into the atmosphere (natural and
synthetic) and their impact on climate or
health.
 Studies of acid mine drainage mineralogy
and its impact on heavy metal drainage or
immobilization
 Geomaterials produced to fix radioactive or
toxic elements and their durability.
 Mineral barriers used to contain radioactive
or toxic elements and their durability.
 Mineral waste materials and their
diagenesis.

16. Note
21 November 2015 Prof. Dr. H.Z. Harraz Presentation Applied Mineralogy, Introduction 16
• Compounding raw materials can be toxic, and
therefore due caution should always be exercised
in the use of these hazardous materials.
• Final determination of the suitability of any
information or product for use contemplated by
any user, and the manner of that use is the sole
responsibility of the user.
• We strongly recommend that users seek and
adhere to a manufacturer’s or supplier’s current
instructions for handling each material they use.

17. 21 November Prof. Dr. H.Z. Harraz Presentation Applied Mineralogy, Introduction 17
Applied mineralogy
and cultural heritage
 Archaeometry,
 Ornamental stone
Applied mineralogy and the
development of instrumentation
 A mineralogical approach to material analysis will only attract
attention if corresponding equipments for mineral quantification /
identification are made available. Because of its applied nature,
applied mineralogy is particularly concerned by the development
of quantitative instruments and instruments that can be put on-
line or automated (at least in the long term). Instruments
requiring large scale facilities (synchrotron radiation, etc…) are
less concerned.
 Quantitative instrumentation cannot be recognized in the
industrial world if it does not evolve towards recommendations
about standards, norms,.. and if it does not state the accuracy of
the method. The community of applied mineralogists should
therefore promote round robin tests among its members.
 Essential techniques used in applied mineralogy include :
 Optical Microscopy
 Electron Microscopy
 Micro-analysis techniques in SEM or TEM conditions (EDX,
WDX, EBSP, CL,…)
 X-Ray Diffraction
 Size distribution analysis techniques
 Porosity and pore size distribution analysis techniques
 Signal and image analysis techniques (Rietveld refinement,
Liberation analysis, etc.)

18. What Applied Mineralogy is not…
21 November Prof. Dr. H.Z. Harraz Presentation Applied Mineralogy, Introduction 18
 Applied Mineralogy is not concerned with:
 Systematic classification of minerals,
 Inventary of mineral species,
 Synthetization of new mineral compounds,
 Crystallographical computations and simulations,
………. etc.
 In a more general sense, applied mineralogy is not
concerned with mineralogical investigations of natural
(geological) processes without any reference to the
potential use or potential environmental impact of such
mineral materials.

19. History
21 November Prof. Dr. H.Z. Harraz Presentation Applied Mineralogy, Introduction 19
 Applied mineralogy is as ancient as humankind if we consider that the
proper choice of a material for making a tool implied already some
kind of "applied mineralogy" knowledge.
 But, of course, considering that Applied Mineralogy can only result
from a proper understanding of our mineralogical environment we
cannot refer to the field before the XVIIth century.
 Padre Alonso Barba's "El arte de los metales" or Henkel's
"Pyrotologia" textbooks are some important landmarks in the
understanding of minerals and their link with mineral processing or
metallurgy.
 But the first book that explicitly refers to the expression of Applied
Mineralogy is probably the one of C.P. Brard written in 1821 and
entitled:
"Minéralogie Appliquée aux Arts"
ou Histoire des minéraux qui sont employés dans l'agriculture, l'économie
domestique, la médecine; la fabrication des sels, des combustibles et des
métaux; l'architecture et la décoration; la peinture et le dessin; les arts
mécaniques; la bijouterie et la joaillerie.

21. Mineral Groups
21 November Prof. Dr. H.Z. Harraz Presentation Applied Mineralogy, Introduction 21
 Rock-forming minerals
 ~30 common minerals make up most rocks in Earth’s crust
 Composed mainly of the 8 elements that make up over 98% of the crust
 Silicates (most abundant)
 Non-silicates (~8% of Earth’s crust):
 Native elements (monoelemental composition--lack of anion; single elements;
e.g., Au)
 Oxides ( main anion is O2-)
 Hydroxides ( main anion complex is OH-)
 Carbonates ( main anion is the oxyacid anion, (CO3)2-)
 Halides (main anion is Cl-, F-, Br- or I-)
 Sulfates (SO4)2-
 Sulfides, sulfarsenides, arsenides, sulfosalts ( main anion is S2- or As3-)

23. Silica Structure
21 November Prof. Dr. H.Z. Harraz Presentation Applied Mineralogy, Introduction 23
• 4 oxygen atoms for every 1
silicon atom
• The basic building block of the
silicates is the silica tetrahedron.
• Each silicon atom is attached to
four oxygen atoms by tetahedral
bonds. This results in a 4- charge
on the SiO4 group.
