Barite or barium sulfate is a chemical mineral found naturally in nature as heavy white crystals. This material is used in various industries due to its high density. In the oil and gas industry, barite is used as a weighting agent in drilling mud to maintain well stability. It is also used in the paint and coatings industry as a filler and a material that helps create texture and resistance. Barite is also used in medicine as a contrast material in medical imaging (such as gastrointestinal imaging) because it absorbs X-rays well.

Environmental impact of Barite
Pollution of surface and underground water: When barite is extracted and used in oil and gas drilling, some of it may enter surface or underground water. While barite is not directly toxic, water contamination can affect aquatic and plant life, causing increased sedimentation and problems for local ecosystems.
Dust and air pollution: In the process of barite extraction and processing, the production of dust can lead to air pollution. This dust may be scattered in the local environment and negatively affect the air quality and respiratory health of people and animals.
Creation of mineral waste: During the mining of barite, tailings and mineral waste are produced, and their management is very important to prevent environmental pollution. These wastes may contain chemicals or heavy metals that can leach into soil and water.
To reduce the environmental impact of barite, it is recommended to use more sustainable methods in extraction, treatment and waste disposal, and to comply with environmental standards.
Safety Measures and Regulations for Handling Barite
Barite is known as a safe chemical substance, but in the process of extraction, transportation and use in industries, there are security considerations that are important to observe.
Packing
Barite is packed in jumbo bags or 25 kg plastic bags.
