Asbestiform Minerals and Human Health. Asbestos is a commercial-industrial term with a long history, and is not a mineralogical definition.

‘‘Asbestos’’ in the latter half of the 20th century became widely used in regulatory language to refer to well developed, long, thin particles (fibers or fibrils) and fiber bundles of specific mineral compositions, which have fulfilled particular.

Palygorskite or attapulgite is a magnesium aluminium phyllosilicate with formula (Mg,Al) 2 Si 4 O 10 (OH)4(H 2 O) that occurs in a type of clay soil common to the Southeastern United is one of the types of fuller's smaller deposits of this mineral can be found in Mexico, where its use is tied to the manufacture of Maya blue in pre-Columbian ry: Phyllosilicate.

The palygorskite-sepiolite group of clay minerals has a wide range of industrial applications derived mainly from its sorptive, rheological and catalytic properties which are based on the fabric Author: Emilio Galán.

2 The Asbestiform and Nonasbestiform Mineral Growth Habit and Their Relationship to Cancer Studies The goal of this document is to clearly and succinctly demonstrate that mineralogical and biological differences exist between asbestos and common nonasbestiform minerals.

Palygorskite, also known as attapulgite, is an odd mineral. It forms matted felted masses that closely resemble woven cloth. In fact, an informal name for this natural fabric is "Mountain Leather" and appears with attached calcite crystals that look like interwoven glass beads.

Palygorskite is often classified as a clay mineral because it is present in some soils and behaves like many other.

Nonoccupational health risks associated with exposure to airborne asbestiform11The term ''asbestiform'' in this report refers to fibers that share some specific physical properties with asbestos.

These are described later in this summary and in Chapter 2. The term is a mineralogical one that has been used for more than a century. fibers have aroused concern because the adverse effects from. The aim of this comprehenvise book is to present the most important results achieved in the research of the clay minerals palygorskite and sepiolite.

Palygorskite and sepiolite have found to be useful in a huge variety of industrial and medical a result, research on these clays has been intensified during the last two decades, and important advances in their characterization. Palygorskite, a fibrous magnesium aluminum silicate.

The structure of palygorskite contains extended silicon-oxygen sheets, justifying the retention of the mineral in the layer silicate family, but the tetrahedral SiO 4 groups forming these sheets are oriented in such a manner as to develop extended lathlike features that give rise to the fibrous morphology.

Palygorskite is a rare, fibrous clay (Mg 2 Al 2 Si 8 O 20 (OH) 2 (OH 2) 4 M +.(H 2 O) 4) which is also known as Attapulgite or fuller’s cial deposits form under alkaline conditions in inland lakes or closed marginal marine basins.

Small deposits are also associated with hydrothermal alteration of magnesium-rich rocks. Asbestiform is a word applied to mineral fibres which are not classified as asbestos but have the same dimensional parameters (length 5 5 m m, diameter 4 3 m m, length/diameter ratio 5 Early measurements of Lyubovtseva and Plakhina () indicated that the scattering matrices of mineral particles (montmorillonite and palygorskite, Figure ) have as non-zero elements only m 12 = m 21, m 22, and m 33 = m 44 (the element m 11 ≡ 1).

The particle diameters were on. Owing to their absorptive properties, sepiolite and palygorskite are used commercially as carriers, fillers, clarifying agents, and in used lubricant reclamation. The fibrous nature of sepiolite and palygorskite precludes the production of oriented aggregate mounts to enhance the reflection for X-ray powder diffraction (Wilson, ).

The palygorskite–sepiolite group consists of palygorskite, sepiolite, falcondoite, kalifersite, loughlinite, raite, tuperssuatsiaite, and ilite is given in the table for comparison.

Each mineral of Table 1 is trioctahedral, except for palygorskite and its Mn analogue, yofortierite, which are dioctahedral. “Attapulgite” was a name introduced by de Lapparent () for a Cited by: ⓘ Day Book No.

Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a.

Furthermore, the asbestiform habit controls many of the physical properties of asbestos. Because of the distinctive characteristics of the asbestiform habit, populations of asbestiform amphiboles can be distinguished from populations of amphibole cleavage fragments by light by: 5.

The tremolite, anthophyllite and serpentine occur as mineral fragments and not as asbestiform fibres. Tremolite from this deposit has been characterized in detail (Campbell et al., ). Nytal also contains asbestiform fibres of talc and talc intergrown on a nanoscale with amphibole (Wylie et al., ).

The problem of asbestiform particulates with its environmental and health implications has been compounded by the lack of precision with which the term "asbestos" has been used. In many instances, nonasbestiform mineral particles have been identified as microscopic fibers of asbestos-related minerals.

Attapulgite, Palygorskite. Attapulgite is a magnesium aluminum silicate clay of very fine particle size. It is also known as Fullers Earth and is closely related to Sepiolite mineral. Unlike bentonite (or montmorillonite) attapulgite crystals are needle shaped (acicular) rather than flat or flake-like.

INTRODUCTION Attapulgite had been used by industry for more than 40 years before it was recognized as a distinct clay mineral. Chemical composition and some of its properties were sufficiently similar to montmorillonite to cause this con- fusion.

Glossary Hazards Minerals Properties Firing Schedules Temperatures Troubles Tests Media Pictures Typecodes Projects URLs Suppliers Schools Consultants Hardness. Hardness is determined by scratching the mineral with a mineral or substance of known hardness.

Hardness is a relative scale, thus to determine a mineral's hardness, you must determine that a substance with a hardness greater than the mineral does indeed scratch the unknown mineral, and that the unknown mineral scratches a known mineral of lesser hardness.

Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many micas vary in chemical composition but are all sheet silicate minerals with very similar physical properties.

Palygorskite has remarkable rheological properties and was used to increase the stability and viscosity of aqueous suspensions. The effects of different physical and chemical processing methods on the apparent viscosity and plastic viscosity of the palygorskite suspensions such as pressing, ultrasound scattering, acidification, and chemical additives have been by: 2.
