Calcinated or agglomerated dolomite

CPC v2.1 Code: 3745

About calcinated or agglomerated dolomite

cpc code 3745 covers the production of calcinated or agglomerated dolomite, a crucial mineral used in a variety of industries. Dolomite is a naturally occurring rock composed of calcium and magnesium carbonates, and its calcination or agglomeration process transforms it into a versatile material with a wide range of applications. This industry plays a vital role in the construction, steel, and chemical sectors, contributing to the broader economy through the supply of essential raw materials.

Production process

The production of calcinated or agglomerated dolomite typically involves a multi-step process. First, the raw dolomite is extracted from quarries or mines. It is then crushed, ground, and screened to achieve the desired particle size. The processed dolomite is then subjected to high-temperature calcination, where it undergoes thermal decomposition, driving off carbon dioxide and leaving behind a porous, reactive material. In some cases, the calcinated dolomite may be further agglomerated, a process that involves binding the particles together to create larger, more uniform pieces.

Production inputs

The main inputs required for the production of calcinated or agglomerated dolomite include the raw dolomite mineral, which is the primary raw material. Additionally, the process requires specialized equipment such as crushers, grinders, and high-temperature furnaces or kilns to facilitate the calcination and agglomeration steps. Energy sources, such as natural gas or electricity, are also crucial inputs for the production process.

Production outputs

The primary output of this industry is calcinated or agglomerated dolomite, which is used in a variety of applications. The calcinated dolomite is commonly used as a refractory material in the steel industry, as a flux in the production of 3312 Iron and Steel, and as a filler or additive in the 3251 Basic Chemical, 3273 Ready-Mix Concrete, and 3274 Lime and Gypsum Product industries. The agglomerated dolomite may also be used in construction materials, such as 3273 Ready-Mix Concrete and 3274 Lime and Gypsum Product.
