MINERALS SORTED BY NAME Here is an alphabetical list of minerals discussed on this site. More information on and photographs of these minerals in Kentucky is available in the book “Rocks and Minerals of Kentucky” (Anderson, 1994). APATITE Crystal system: hexagonal. Fracture: conchoidal. Color: red, brown, white. Hardness: 5.0. Luster: opaque or semitransparent. Specific gravity: 3.1. Apatite, also called cellophane, occurs in peridotites in eastern and western Kentucky. A microcrystalline variety of collophane found in northern Woodford County is dark reddish brown, porous, and occurs in phosphatic beds, lenses, and nodules in the Tanglewood Member of the Lexington Limestone. Some fossils in the Tanglewood Member are coated with phosphate. Beds are generally very thin, but occasionally several feet thick. The Woodford County phosphate beds were mined during the early 1900s near Wallace, Ky. BARITE Crystal system: orthorhombic. Cleavage: often in groups of platy or tabular crystals. Color: usually white, but may be light shades of blue, brown, yellow, or red. Hardness: 3.0 to 3.5. Streak: white. Luster: vitreous to pearly. Specific gravity: 4.5. Tenacity: brittle. Uses: in heavy muds in oil-well drilling, to increase brilliance in the glass-making industry, as filler for paper, cosmetics, textiles, linoleum, rubber goods, paints. Barite generally occurs in a white massive variety (often appearing earthy when weathered), although some clear to bluish, bladed barite crystals have been observed in several vein deposits in central Kentucky, and commonly occurs as a solid solution series with celestite where barium and strontium can substitute for each other. Various nodular zones have been observed in Silurian–Devonian rocks in east-central Kentucky. -

Gem Water cover:fa 17/5/09 23:06 Page 1 GEM WATER Adding crystals to water is both visually appealing and healthy. The water becomes infused with crystalline energy. It is a known fact that water carries mineral information and Gem Water provides effective remedies, acting quickly on a physical level. It is similar and complementary to wear- ing crystals, but the effects are not necessarily the same. The introduction to the book tells you all you need to know about the correct way to prepare Gem Water and pro- vides important information on which crystals to use and which not to prepare as Gem Water. The concept may appear simple at first, but you need to apply it with care, and the book explains all the facts you need to know before getting started.

Selective Flotation of Witherite from Calcite Using Potassium Chromate As a Depressant

However, few studies have been conducted to effectively concentrate witherite from barium ores. In this work, with the treatment of potassium chromate (K2CrO4) and sodium oleate (NaOL), witherite was selectively separated from calcite through selective flotation at different pH conditions. In addition, contact angle, Zeta potential, adsorption and X-ray photoelectron spectroscopy measurements were performed to characterize the separation mechanisms. The results demonstrated that NaOL had a strong collecting ability for both witherite and calcite; nevertheless, witherite could be effectively selected from calcite with the highest recovery at pH 9 in the presence of K2CrO4. From the XPS measurements, NaOL and K2CrO4 were found to be primarily attached to the surfaces of witherite and calcite through chemisorption. The presence of K2CrO4 on the surface of calcite adversely influenced the NaOL adsorption, which could make the flotation separation efficient and successful. -

The Minerals and Rocks of the Earth 5A: the Minerals- Special Mineralogy
Lesson 5 cont’d: The Minerals and Rocks of the Earth 5a: The minerals- special mineralogy A. M. C. Şengör In the previous lectures concerning the materials of the earth, we studied the most important silicates. We did so, because they make up more than 80% of our planet. We said, if we know them, we know much about our planet. However, on the surface or near-surface areas of the earth 75% is covered by sedimentary rocks, almost 1/3 of which are not silicates. These are the carbonate rocks such as limestones, dolomites (Americans call them dolostones, which is inappropriate, because dolomite is the name of a person {Dolomieu}, after which the mineral dolomite, the rock dolomite and the Dolomite Mountains in Italy have been named; it is like calling the Dolomite Mountains Dolo Mountains!). Another important category of rocks, including parts of the carbonates, are the evaporites including halides and sulfates. So we need to look at the minerals forming these rocks too. Some of the iron oxides are important, because they are magnetic and impart magnetic properties on rocks. Some hydroxides are important weathering products. This final part of Lesson 5 will be devoted to a description of the most important of the carbonate, sulfate, halide and the iron oxide minerals, although they play a very little rôle in the total earth volume. Despite that, they play a critical rôle on the surface of the earth and some of them are also major climate controllers. The carbonate minerals are those containing the carbonate ion -2 CO3 The are divided into the following classes: 1. -
