These residues were converted to natural bitumen under the pressure of the upper sedimentary layers and temperatures above 50 °C.Bitumen is now found in hills and oil lakes. Most of the bitumen resources are in Canada, Venezuela, and Oman. There are also natural bitumen mines in the west of Iran. It has different ash content.Natural bitumen or Gilsonite has many impurities including sulfur and heavy metals. The cost of extracting and using this bitumen is higher than the bitumen obtained from crude oil.It is usually used as an additive for waterproofing coating, mud drilling, and road construction.2. Crude Oil DistillationCrude oil is the primary source of bitumen for the industry. Crude oil is a mixture of different compounds that is separated by a distillation tower. The remnants of the distillation tower, called vacuum bottom, are transferred to be processed and turned into bitumen.Different types of bitumen, including penetration bitumen or oxidized bitumen, are produced by a different process on vacuum bottom in the refinery. The main application of this bitumen is in road construction.Read the different types of bitumen used in road construction to know more details.To become familiar with the way bitumen is created in nature, how it is extracted from oil, what its classifications are, and what uses it has, watch the below video:What is the Difference Between Bitumen, Tar, and Asphalt?In the United States, the words bitumen and asphalt are synonymous, but in general, asphalt means the composition of aggregates and bitumen, as a binder, that is
