History

Methods of processing minerals have been known to people for thousands of years. Mining, which initiated the history of the development of technology and significantly influenced the formation of human society, was an inalienable component of the activity of human tribes.

 

Retrospective analysis of mining allows us to detect the following landmarks in its development:

 

  • in the 7th millennium B.C. and earlier, non-metallic raw materials were mined;
  • from the 7th to 5th millennia B.C. production of colored metals, such as copper, gold, tin, and antimony, began;
  • the period from the 1st millennia B.C. saw the beginning of iron ore mining;
  • antiquity and the middle ages saw coal and oil deposits start to be developed;
  • the 20th century saw the beginning of the exploitation of radioactive minerals.

 

The oldest mining technology is open-cut and shaft mining. In the 1st millennium B.C. borehole mining technology appeared and in the 1950s people started developing deposits at the bottoms of the seas and oceans.

Open-cut mining has been practiced since the Paleolithic Age. The first major quarries appeared in connection with the pyramids construction in Ancient Egypt. Later, in antiquity, marble was quarried in large quantities.

 

Expansion of open-cut mining in quarries was delayed until the beginning of the 20th century due to the absence of highly-productive machinery for extracting and moving large quantities of overburden rock. In the second half of the 20th century, complex mechanization began. By the end of the 20th century, every year around 120 billion tons of rock and 25 billion tons of minerals were being extracted.

 

Hard (rock) types such as granite, gravel, sandstone, and limestone were used for centuries to construct buildings, roads, and monuments.

 

People have long used granite as a building stone thanks to its homogeneous structure, pleasant coloration, and high solidity, and because it is relatively simple to extract and process. Granite's main drawbacks are its rough surface, which accumulates dirt and soot, and that it cracks and crumbles fast in fire. Approximately half of the granite quarried finds (according to its value) use as dimension stone (for floors or walls) or as a facing stone - that is, as blocks and slabs. The other half is used in crushed and ground form.

 

Aggregates were widely used as a construction material back in the Roman Empire. Roman roads have been famous throughout history, and were built of granite slabs and aggregates. History shows that those roads were quite effective in fostering efficient transportation and remained well-preserved even after the passage of centuries. Today production of aggregates is adjusted to new clients' requirements and to the wide range of the product's application. More than 3 billion m3 of aggregates are produced worldwide every year.

Lafarge and Aggregates

Lafarge's aggregates production branch experienced rapid growth after the acquisition of the following companies:

  • Redland, one of the world's leaders in aggregates production and concrete mixtures, in 1997.
  • Blue Circle, in 2001.

In Ukraine, the appearance of the Lafarge Aggregates Ukraine subdivision dates from September of 2004, when LLC KKNK "Technobud" became a part of the Lafarge Group.
