Coal mining is the process of extracting coal from underground or surface mines. Coal has been a crucial energy source since the 1880s, primarily used for electricity generation, steel production, and industrial heating. The mining process involves surface mining (such as strip mining) and underground mining, depending on the depth and location of coal deposits. Despite its economic importance, coal mining poses environmental challenges, including land degradation and carbon emissions.
Rare earth elements (REEs) are a group of 17 chemically similar metallic elements crucial for modern technology and industrial applications. They are used in the production of high-strength magnets, batteries, electronics, and advanced military equipment. Extracting and refining REEs is a complex process that involves mining, chemical separation, and purification. Due to their scarcity and demand, rare earth elements play a strategic role in global trade and technological development.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.

The history of agriculture began thousands of years ago.
The machine industry or machinery industry is a subsector of the industry, that produces and maintains machines for consumers, the industry, and most other companies in the economy. This machine industry traditionally belongs to the heavy industry. Nowadays, many smaller companies in this branch are considered part of the light industry. Most manufacturers in the machinery industry are called machine factories.
A laboratory is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings: physicians offices, clinics, hospitals, and regional and national referral centers.
