Study with Quizlet and memorize flashcards containing terms like What makes a mineral an ore?, Is aluminum an ore? Explain your answer., Can the classification of a mineral as an ore change? If so, how? and more.
Dolomite is used as an ornamental stone, as a raw material for the manufacture of cement, and as a source of magnesium oxide. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals (that is, readily oxidized metals) such as lead, zinc, and copper.
Dolomite is the primary ore for magnesium metal and is quarried for building material, road stone, or refractory brick production.
Malachite is the ore of copper. Malachite is a copper carbonate hydroxide. It's formula is Cu2CO3(OH)2.
In extraction of metal how many of the following ores involves calcination process.

Practice Class 12 Chemistry Chapter 6 MCQs on General Principles and Processes of Isolation of Elements, designed for CBSE, ICSE, IGCSE, NCERT, and State Level Exams!
Magnesium (see dolomite) is used in cement, rubber, paper, insulation, chemicals and fertilizers, animal feed, and pharmaceuticals. Magnesium is obtained from the ore minerals Olivine (Fe,Mg) 2 SiO 4, Magnesite MgCO3, and Dolomite CaMg (CO 3) 2 .
As interesting as dolostone is, especially when it produces nice crystals, the dolomite we are most interested in is not a huge rock formation, but lovely crystallized specimens that are found in Spain, …
Dolomite is a metastable mineral, early formed crystals can be replaced by later more stable phases with such replacements repeated a number of times during burial and metamorphism. Each new phase is formed by the partial or complete dissolution of an earlier dolomite. This continual re-equilibration during burial detracts from the ability of …
Mineral resource diversity in Karnataka. Karnataka has more than with 40,000 sq. km of green stone belts abundant with a variety of mineral resources like gold, silver, copper, iron, kaolin, manganese, limestone, ochre, quartz, dolomite, chromite, silica sand, granite, and other useful rock formations. The state is the sole producer of felsite ...
Fine-scale metal depletion cycles during this transition may record metal precipitation from brine in response to the availability of reduced sulfur. Except for Fe and Mn, post-ore dolomite zones ...
The extraction of metal from an ore is not economically feasible. Complete answer: Dolomite contains calcium carbonate and magnesium carbonate. Thus, it is a carbonate ore. We can write the chemical formula of Dolomite as either. CaCO3, MgCO3 CaC O 3, MgC O 3. or. CaMg(CO3)2 CaMg ( C O 3) 2. Calamine is zinc carbonate.
The role of ore mineralogy in selecting the most adequate concentration method for magnesite-dolomite separation was found to be detrimental.
A. Carnallite. B. Magnesite. C. Dolomite. D. All of these. Identify the ores of magnesium... Hint: Magnesium is obtained from its ore. M agnesium ores are used commercially and magnesium metal can be extracted by electrolysis or by the process of thermal reduction. Magnesium and its compounds are used in many works such as …

Aluminium is extracted from bauxite ores. Aluminium has become a very important mineral in our times because of its lightweight. It is used in making aircrafts utensils, electric wires etc, and also extensively in the packaging of food products.
This metal is highly reactive and is present in a wide variety of brines, rocks, and seawater. Numbers of metals can be formed from Magnesium using the "thermal reduction" of the salt of Magnesium and its oxidised form. The most common ore mineral of Magnesium is dolomite. Dolomite is made with Magnesium and calcium carbonate.
Therefore, to further understand the effects and mechanism of metal ions on the flotation of the phosphate ore, it was necessary to first explore the effects of metal ions on the flotation behaviors of apatite, dolomite, and quartz, separately.
