What is an ore example?
Ores are minerals that have a high concentration of a certain element, typically a metal. Examples are cinnabar (HgS), an ore of mercury, sphalerite (ZnS), an ore of zinc, or cassiterite (SnO2), an ore of tin (Mineral).
Which is an ore?
Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.
What are the types of ore?
There are mainly four kinds of ores like Ores Oxides; Ores Carbonate; Sulphide Ores; Ores Halides.
What is an ore Class 5?
Ores are a mixture of minerals: processed to produce an industrial mineral or chemically treated to produce one or more metals. The steel, aluminum, chromium, zinc, mercury, manganese, tungsten, and some copper ores are typically processed for just one element.
Is Diamond an ore?
There is no mineral ore of diamond. An ore is a rock which is crushed, refined, treated & something is retrieved from it by physical or chemical processes. Diamonds are found within kimberlite, & in Australia in lamproite, but diamond is a crystal of carbon & is not part of the rock, so the rock is not an ore.
Which ore contains both K and Mg?
dolomite
Which contains both magnesium and calcium?
Dolomite
Which contains both Ca and Mg 3 points?
For Dolomite, We have to know that, Dolomite is an anhydrous carbonate mineral made out of calcium magnesium carbonate, in a perfect world CaMg(CO3)2 . Here, both the magnesium and calcium are present.
Which is an ore of dolomite?

What good is Dolomite?
Dolomite, a type of limestone, provides valuable nutrients to plants and helps change the pH of the soil by raising it to match the plants’ needs. It’s sometimes called dolomitic lime or dolomitic limestone, and provides more nutrients than straight lime.
Does Dolomite fizz in acid?
Dolomite will effervesce weakly with cold hydrochloric acid, producing a few bubbles. The reaction is more noticeable when the acid is warm and/or the stone is powdered.
Where is dolostone formed?
Dolostone was formed in warm, clear, shallow seas during the Paleozoic Era. A comparable modern-day environment that could produce both limestone and dolostone is the Caribbean Sea. Dolostone also is one of Ohio’s important industrial minerals.
How is a dolostone formed?
Dolostone forms when magnesium in pore water is substituted for some of the calcium in the original limestone, or by direct precipitation. Most limestones of commercial importance accumulated in relatively shallow marine environments and are widely available for utilization.
Is dolostone chemically formed?
Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.
How is Micrite formed?
Micrite is a limestone constituent formed of calcareous particles ranging in diameter up to four μm formed by the recrystallization of lime mud. Micrite is lime mud, carbonate of mud grade. Micrite can be generated by chemical precipitation, from disaggregation of peloids, or by micritization.
What Micrite looks like?
Micrite is “lime mud”, the dense, dull-looking sediment made of clay sized crystals of CaCO3. Much micrite today forms from the breakdown of calcareous algae skeletons. If we could see the sediment during deposition all the allochems would be loose, like a pure sand or gravel.
Where is Micrite found?
Extremely fine-grained texture; micrite is carbonate mud (most common component of carbonate rocks); dull, opaque, and aphanitic in hand sample; white to black. origin: Produced from deposits of fine lime mud in areas with little current or wave action; generally found in central parts of seas.
Is Micrite a cement?
Folk (1959) introduced a term known as micrite to refer to matrix which characterizes low-energy deposits. Micrite is a contraction of “microcrystalline ooze” (Folk 1962, p. micritic) cement, as used by Hook and others (1984), is a contradiction.
What minerals are in Micrite?
Micrite = lime mud; CaCO3, the mineral calcite. Micrite is the equivalent of clay (rock = shale) in clastics. Originally deposited as microscopic aragonite needles, but now converted to calcite and then calcite cemented to form the rock. See Origin of Micrite for more details.
What is Sparite?
Sparite is the coarse crystalline calcite cement which fills pore spaces in many limestones after deposition, formed by the precipitation of calcite from carbonate-rich solutions passing through the pore spaces in the sediment.
