What is mining in cement industry?

Different minerals need to be mined in order to make cement. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.

What duties does a mining engineer perform at there job?

Mining and geological engineers typically do the following:

• Design open-pit and underground mines.
• Supervise the construction of mine shafts and tunnels.
• Devise methods for transporting minerals to processing plants.
• Prepare technical reports for miners, engineers, and managers.

What does mechanical engineer do in cement industry?

Role of mechanical engineers are in operation, maintenance, project, procurment, and based on seniority they have higher responsibility and authority. All cement plants are reaping big profits so engineers get handsome pay package.

What are mining engineers called?

miner
The mining engineer can be legally identified as a “miner.”

What is used in cement industry?

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

What rocks are in cement?

Cement manufacture involves a mix or raw materials, typically about 85\% limestone (or similar rocks like marble or marl) with the rest mainly clay or shale. This mixture is heated until it nearly melts, and is then ground into a powder. It takes about 1.7 tons of raw materials to make 1 ton of cement.

Where can Mining Engineer work?

Mining engineers work mostly in mining operations in remote locations. However, some work in sand-and-gravel operations located near large cities. Over time, they may work their way up to office positions in mining firms or consulting companies, which are usually located near large metropolitan areas.

Is cement industry a mineral industry?

Cement Industry. These industries use minerals, both metallic and non-metallic, as raw materials and are based on ferrous and non-ferrous metallurgical processes. The major mineral-based industries include iron and steel, cement, basic and light chemicals and fertilisers.

What is the role of cement in concrete?

Cement plays a major role within a concrete mixture and affects most important aspects of the mix, such as: workability, compressive strength, drying shrinkage, and durability. Through the process of hydration, cement particles react with water, binding the aggregate, and the strength matrix develops (Weiss, 1999).
