Bauxite Certified Reference Material: A Collaboration of NALCO and BARC

Understanding Bauxite Certified Reference Material (CRM)

The Bauxite CRM is essentially a bauxite sample that is used as a standard in the analysis of bauxite samples in laboratories.

• The CRM is manufactured under rigorous quality control processes to guarantee its precision and stability.
• The importance of Bauxite CRMs cannot be overstated as the quality of bauxite directly influences the quality of the resulting aluminium.
• Reliable and accurate Bauxite CRMs are crucial for the aluminium industry to consistently produce high-quality products.
• This CRM will aid in maintaining the quality and consistency of aluminium production by providing dependable standards for laboratory analysis.
• CRMs are used as calibration standards for analytical methods, instrument performance evaluation, and data quality control in routine analysis of bauxite.
• The Bauxite CRM has been certified for nine property values – Al2O3, Fe2O3, SiO2, TiO2, V2O5, MnO, Cr2O3, MgO and LOI which are traceable to the international system of units.

What Exactly is Bauxite?

Bauxite is a sedimentary rock that is the world’s primary source of aluminium.

• It is created through the weathering of aluminium-rich rocks in tropical and subtropical regions.
• Primarily composed of aluminium hydroxides, bauxite also contains other minerals such as iron oxides, titanium dioxide, and silica.
• The quality of bauxite is gauged by its alumina content, with higher alumina content resulting in superior quality aluminium.
• Australia, Guinea, and Brazil are the largest producers of bauxite, followed by China and India.
• Bauxite is typically extracted through open-pit mining, which involves the removal of overburden (the topsoil and vegetation covering the deposit) and the excavation of the ore underneath.
• The bauxite ore is then transported to a processing plant where it is refined to extract aluminium oxide (alumina).
• Alumina can be further processed to produce aluminium metal through electrolysis.
• The aluminium industry, which uses bauxite to produce everything from beverage cans to aircraft parts, is a major consumer of bauxite.

About NALCO

• National Aluminium Company Limited (NALCO) is a Navratna CPSE (Central Public Sector Enterprise) under the Ministry of Mines, Government of India.
• As a leading manufacturer and exporter of alumina and aluminium, NALCO has integrated operations from mining to metal production. The company owns its own bauxite mines, alumina refineries, smelter plants, and power generation facilities.
• NALCO is dedicated to sustainable development and has implemented various measures to minimize its impact on the environment. Through various corporate social responsibility (CSR) initiatives, NALCO also contributes to the social and economic development of the communities in and around its operations. NALCO has consistently ranked among the top CPSEs in terms of financial performance and market capitalization.

About BARC

• BARC, located in Mumbai, is India’s premier nuclear research facility.
• It was established in 1954 under the guidance of Dr. Homi J. Bhabha, the father of India’s nuclear program.
• The primary objective of BARC is to develop nuclear technology and applications for peaceful purposes, including energy generation, healthcare, agriculture, and industry.
• BARC operates several nuclear reactors, including India’s first nuclear power plant, Tarapur Atomic Power Station.
• BARC is also involved in research and development in fields such as materials science, radiation biology, and nuclear physics.
• BARC has collaborations with various national and international institutions, and it offers training and education programs in nuclear science and technology.
• The Department of Atomic Energy (DAE), which is responsible for India’s nuclear program, governs BARC.
