  • How Cement Is Made

    Cement is so fine that 1 pound of cement contains 150 billion grains The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process...

  • Effectiveness of Olivine

    of dunite for DW treatment, whereas the second aim of the study is to investigate a harzburgitic rock for AMD management The effectiveness of dunite and harzburgite is also compared For these purposes, olivine-rich ultrabasic rocks from two different ophiolitic sequences were selected (Fig 1)...

  • Chemical process

    In a scientific sense, a chemical process is a method or means of somehow changing one or more chemicals or chemical compoundsSuch a chemical process can occur by itself or be caused by an outside force, and involves a chemical reaction of some sort In an "engineering" sense, a chemical process is a method intended to be used in manufacturing or on an industrial scale (see Industrial process ....

  • Peridotite

    Peridotite is a dense, coarse-grained igneous rock consisting mostly of the minerals olivine and pyroxenePeridotite is ultramafic, as the rock contains less than 45% silicaIt is high in magnesium (Mg 2+), reflecting the high proportions of magnesium-rich olivine, with appreciable ironPeridotite is derived from the Earth's mantle, either as solid blocks and fragments, or as crystals ....

  • Peridotite: Igneous Rock

    What is Peridotite? Peridotite is a generic name used for coarse-grained, dark-colored, ultramafic igneous rocks Peridotites usually contain olivine as their primary mineral, frequently with other mafic minerals such as pyroxenes and amphibol Their silica content is low compared to other igneous rocks, and they contain very little quartz and feldspar...

  • The Density of Common Rocks and Minerals

    The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3...

  • Rock Identification Made Easy

    In simple terms, hard rock scratches glass and steel, usually signifying the minerals quartz or feldspar, which has a Mohs hardness of 6 or higher Soft rock does not scratch steel but will scratch fingernails (Mohs scale of 3 to 55), while very soft rock won't even scratch fingernails (Mohs scale of 1 to 2)...

  • Dunite cement

    Dunite Yoko-Tovarenska array (Northern, Pribaikalsky is), included in the cement composition is ultramafic rock are the following chemical composition, wt% (see table 1) In the composition of the rocks predominate (85-98%) group minerals olivine: olivine (Mg, Fe) 2 [SiO 4 ], fayalite Fe 2 [SiO 4 ], forsterite Mg 2 [SiO 4 ]...

  • How diamond is made

    The diamond is the hardest natural substance known It is found in a type of igneous rock known as kimberlite The diamond itself is essentially a chain of carbon atoms that have crystallized The stone's unique hardness is a result of the densely concentrated nature of the carbon chains...

  • Formation of soil

    Sep 03, 2015· There are two processes of soil formation ie physical disintegration & chemical decomposition of rocks Formation of soil takes place without change in parent rock property in case of physical disintegration, while in case of chemical decomposition, properties of parent rock ,...

  • List of Metamorphic Rocks

    Rocks that have been formed from other rocks, sedimentary and igneous, by internal changes caused by pressure, heat, and the chemical action of the solutions and hot gases, are called metamorphic rocks and here is a list: Crystalline Limestone...

  • Biological Weathering

    Biological weathering also means organic weathering It is the disintegration of rocks as a result of the action by living organisms Biological weathering can work hand in hand with physical weathering by weakening rock or exposing it to the forces of physical or chemical weathering...

  • Peridotite: Igneous Rock

    Peridotite is an intrusive igneous rock with an ultramafic composition , Dunite: a peridotite that is composed mainly of olivine and may contain significant amounts of chromite, pyroxene, , the process of seafloor spreading, and the formation of oceanic lithosphere...

  • Igneous Rocks

    Igneous rocks may be simply classified according to their chemical/mineral composition as felsic, intermediate, mafic, and ultramafic, and by texture or grain size: intrusive rocks are course grained (all crystals are visible to the naked eye) while extrusive rocks may be fine-grained (microscopic crystals) or glass (no crystalline structure; i ....
