Dolomite as a Flux in Ore separation.

Dolomite as a flux in ore separation is one of the major use considering the price of it. It is a dry substance which consists of Calcium Magnesium Carbonate as its main substance. It is one of the forms of limestone which are obtained when limestone is mixed with different compounds. Its rock type is also known as dolostone. Dolomite is used as an ornamental substance, as a source of magnesium oxide and it is also used in the process for the production of magnesium. When limestone contains a significant amount of magnesium, it is called dolomite. Moreover, it is used to remove unnecessary material from an ore because we can treat it like a flux.

How Dolomite can be used as a flux?

Flux is a substance which acts as a cleaning agent, purifying agent or as a flowing agent. Fluxes can have multiple operations at a single time.

Dolomite is used in the Steel and Iron industry to remove unnecessary material from the ores.

It is mixed with oxides of magnesium or calcium which will create a substance called flux. Flux will have a low melting point and due to this property of the flux, it can be removed easily by using heating methods that take advantage of different melting points in a substance that contains different compounds.

India is one of the biggest exporters of Dolomite in the following countries. If you want to buy from any of these countries you can contact Mahaveer Ceramic Industries. We manufacture and sell products to own country India and Middle east countries, Oman, Saudi Arabia, African countries and many more countries.

What is the use of Dolomite in Furnaces?

Dolomite in Furnaces –

Dolomite is a dry carbonate mineral which is made of calcium magnesium carbonate or CaMg(CO3)2. The rock type of dolomite is called dolostone. Dolomite is closely related to another mineral called huntite.

Dolomite plays an important role in the iron and steel industry. It is used in blast furnaces in the industry. Dolomite is also used as slag in the process of removal of gangue particles from iron ores.

The use of dolomite in blast furnaces

Dolomite is used in the production of iron because the amount of MgO as a slag can be prefixed by using a different amount of dolomite. During the filtration of iron by blast furnace method dolomite is either used in sintering method or directly inserted into the furnace. In the sintering method, the workpiece is heated at high temperatures, compression can also be used in this method but in this case liquefaction is avoided.

Uses of dolomite in the Iron and Steel industry

In these industries, dolomite plays an important role. Dolomite is used as a refractory material, slag former and as a slag modifier. The process of iron making is the reduction of iron ore to produce iron. Iron ores generally contain unnecessary materials called gangue such as Alumina and Silica with some Sulphur and Phosphorus. We can remove this type of impurities using Cao or MgO by mixing it with gangue particles. This will form slag which will consist of low melting point compounds such as silicate, calcium aluminate, etc. After this step, CaO and MgO are charged along with other raw materials in the form of dolomite. This dolomite firstly decomposed into CaO or CaO+MgO which then combine with gangue to form slag. Now the slag can be removed by simple heating techniques.

Addition of dolomite through sinter is preferred because the CO2 present in the dolomite will be removed in this process. In the case of sintering, the particles of dolomite are crushed to a size of 3mm. However, in the case of direct feeding lumps of dolomite are used.

What is the Difference between Dolomite and Limestone?

Both limestone and dolomite are the rocks which are made up of carbonate. When magnesium level of limestone reaches a certain level, that limestone is called dolomite. But what is the real difference between these carbonates? Let’s take a look:-

dolomite-and-limestone

Limestone –

Limestone is a carbonate which is found at the upper rock layers of the earth. The carbonate rocks of the sedimentary layer are called limestones. About 10% of the rocks in the sedimentary layer are limestones. Limestone has many uses, it is used in toothpaste, it is used in paints, as a soil conditioner, etc.

It is also used as slag in the iron and steel industry. The slag which is formed by limestone has a very low melting point which makes the process of gangue removal easy.

Dolomite –

When the amount of magnesium is reached at a certain level in the limestone, it is converted into a different carbonate known as dolomite. Unlike limestone, dolomite has industrial uses. It is used an ornamental stone, a source of magnesium oxide and a necessary substance in the process to produce magnesium. It is also used to maintain the pH level of water in aquariums.

In the steel and iron industry, it is used as a flux which acts as a cleaning and purifying agent.

Buying Limestone or Dolomite from India can be beneficial for you because of the quality product and affordable price.

We at Mahaveer Minerals sell products to many countries at good price. You can contact us at +919001234111 or visit our website.

Dolomite Grains

Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO3)2.

Dolomite crystals range from transparent to translucent, but dolomite grains in rocks are typically translucent or nearly opaque. The luster ranges from sub vitreous to dull. Dolomite, like calcite, cleaves into six-sided polyhedrons with diamond-shaped faces.
Uses of Dolomite Grains
Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces. The use of dolostone as a flux has increased, especially since environmental contamination has become a widely heeded consideration, because the resulting slag can be employed for such things as lightweight aggregate, whereas that formed when limestone is used cannot. Such is the case because dolostone-based slag does not slake (disintegrate in water), but limestone-based slag does.

Characteristics of Dolomite

Dolomite has properties same as the mineral calcite, but it does not rapidly dissolved in dilute hydrochloric acid because of lesser percent of carbonate presence.

Dolomite lumps are slightly harder, denser and never forms scalenohedrons.
Dolomite decomposed completely above at 900ºC The product resulting from this relatively low-temperature and calcination is highly porous and reactive and is known as ‘calcinated dolomite’.
