Ragedara Mine
Sri Lanka graphite is very high quality with many unique properties. It is suitable for use in many high-end graphite applications.
Quality of Graphite
Tested our material and it is highly recommended for NANO technology.
Refinery Process
Ragedara Mines developed its own unique graphite refining process that does not require the use of acids or alkaline systems.
Research & Development
Graphite conducts heat and electricity more efficiently than copper or any other material known.
ABOUT RAGEDARA GRAPHITE THE COMPANY OVERVIEW
Ragedara Mine is one of the world’s purest vein graphite producers in Sri Lanka. It had been in operation since the early 18th century. The Graphite from Ragedara was tested and was found to be the purest graphite vein in the world. At present, we mine ultra-pure highly crystalline vein graphite with 97% to 99% range of carbon. Over the years, it has been renowned for its superior quality and uniqueness.
The Ragedara mine is administrated by a team of skillful managers, mining, processing & maintenance engineers, and our Board of Directors consist of mainly German qualified engineers.
Since the 18th century, we have had a powerful trademark in Graphite industry. Ragedara Mine has the most concentrated number of veins in the country and it had more than 30 individually separated graphite Pits (Shafts) in it’s our own land. The deepest operating level at Ragedara Mine is at 276ft. Whereas the depths of other main operating graphite mines in Sri Lanka are at 1800ft and 2600ft.
Sri Lanka “Graphite”We produce Graphene, rGO and GO from quality graphite.
LOCATIONS OF THE MINES
Revival of graphite mining in Sri Lanka
The existence of graphite in Sri Lanka (then known as Ceylon) has been known since 1675 when the Dutch governor, mentions the existence of veins of 'pot loop' in the hills and maritime provinces. Serious mining and export of graphite in Sri Lanka began in 1824 with graphite exports peaking in 1899.
Sri Lankan production declined slowly with small revivals during the First and Second World Wars, when 30,000 metric tons of natural graphite was exported per year and over 6,000 shallow workings, pits and Graphite (locally known as ‘Miniran’) mines were mostly located in North Western and South Western parts of the island, with working pits located in Aluketiya, Meegahatenna, Matugama and Agalawatta.
Sri Lanka is the only country to mine ultra-pure highly crystalline vein graphite with more than 98% of carbon purity in the world over the last 100+ years, and it is world renowned for its superior quality and uniqueness.
Natural graphite from Sri Lanka is of very high quality reaching 99.9 percent carbon and the averages vary from 90 to 96 percent. Both lump and flake varieties will be in this range and the main industrial applications are manufactured of crucibles linings of steel furnaces by carbon aluminum bricks, specially in the USA and Japan, carbon brushes, refractory bricks, carbon –cinema arcs, electrodes, paints lubricants and golf sticks. Graphite of high purity is used in TV screens and reactors as a shield to prevent emission of radiation in nuclear power plants.
The Board of Investment (BoI) is now promoting companies especially from China and Australia to invest in mining ventures for graphite in abandoned mining areas and a recent news item in the local media has highlighted an Australian company investing heavily on a survey for graphite around the KK mines.
