Barite is a mineral composed of barium sulfate (BaSO4). It receives its name from the Greek word “barys” which means “heavy.” … Barite Rose: This “barite rose” is a cluster of bladed barite crystals that have grown in sand, incorporating many of the sand grains within each crystal.

Barite

Barite is generally easy to identify. It is one of just a few nonmetallic minerals with a specific gravity of four or higher.

Combine that with its low Mohs hardness (2.5 to 3.5) and its three directions of right-angle cleavage, and the mineral can usually be reliably identified with just three observations.

Physical Properties of Barite

DiaphaneityTransparent to translucent
CleavageVery good, basal, prismatic
Mohs Hardness2.5 to 3.5
Specific Gravity4.5
Diagnostic PropertiesHigh specific gravity, three cleavage directions at right angles
Chemical CompositionBarium sulfate, BaSO4
Crystal SystemOrthorhombic
UsesDrilling mud; high-density filler for paper, rubber, plastics

Most barite produced is used as a weighting agent in drilling muds. This is what 99% of the barite consumed in the United States is used for.

These high-density muds are pumped down the drill stem, exit through the cutting bit and return to the surface between the drill stem and the wall of the well.

This flow of fluid does two things: 1) it cools the drill bit; and, 2) the high-density barite mud suspends the rock cuttings produced by the drill and carries them up to the surface.

Barite is also used as a pigment in paints and as a weighted filler for paper, cloth, and rubber. The paper used to make some playing cards has barite packed between the paper fibers.

This gives the paper a very high density that allows the cards to be “dealt” easily to players around a card table. Barite is used as a weighting filler in rubber to make “anti-sail” mudflaps for trucks.

Hematite, also spelled as haematite, is a common iron oxide with a formula called Fe2O3 and has been widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.

Hematite, also spelled as haematite, is a common iron oxide with a formula called Fe2O3 and has been widespread in rocks and soils.[5] Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.

Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F). Hematite is colored black to steel or silver-gray, brown to reddish-brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite).

While these forms vary, they all have a rust-red streak. Hematite is harder than pure iron but much more brittle. Maghemite is a hematite- and magnetite-related oxide mineral. A microscopic picture of hematite. Large deposits of hematite are found in banded iron formations.

Bentonite Exporter In Pakistan:

EnerQuip Pvt Ltd Company is an exporter and supplier of bentonite from Pakistan to the entire world. We can supply bentonite in any form. I.e: sodium and calcium bentonite.

In stratigraphy and tephrochronology, completely devitrified (weathered volcanic glass) ash-fall beds are commonly referred to as K–bentonites when the dominant clay species is illite.

What is Bentonite?

Bentonite is an absorbent aluminum phyllosilicate clay consisting mostly of montmorillonite. It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.

The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminum (Al).

Experts debate a number of nomenclatorial problems with the classification of bentonite clays. Bentonite usually forms from weathering of volcanic ash, most often in the presence of water.

However, the term bentonite, as well as a similar clay called Aronstein, has been used to describe clay beds of uncertain origin.

For industrial purposes, two main classes of bentonite exist sodium and calcium bentonite. In stratigraphy and tephrochronology, completely devitrified (weathered volcanic glass) ash-fall beds are commonly referred to as K-bentonites when the dominant clay species is illite.

In addition to montmorillonite and illite, another common clay species that are sometimes dominant is kaolinite. Kaolinite-dominated clays are commonly referred to as tonsteins and are typically associated with coal.
