Gujarat Mineral Development Corporation (GDMC) was incorporated in 1963 and is engaged in business of mining and mineral processing. The company was set up to produce major mineral resources in the state of Gujarat. GDMC started its operations with a small sand crushing facility located at Surendranagar that delivered sand to consumers in the state. Sand is majorly used by sodium silicate and glass manufacturers.
The company entered its next venture of beneficiation of fluorspar in the year 1968. Fluorspar is rare mineral and has applications in industries like steel, aluminium, hydrochloric acid, foundry flux and welding electrodes.
In 1970, the company commissioned mining of lignite in the Kutch district. Lignite is a cheaper substitute for coal. Later 1984, GDMC started its mining operations at Rajpardi near Ankleshwar in order to supply lignite to textile industries.
GMDC is the largest merchant seller of lignite in the country. GMDC has brought technology known as TAKRAF of Germany for its exploration activities.
The Corporation first implemented ISO-9001 at Corporate office in 2010 and is planning to obtain for all the mines in operation with Occupational Health and Safety systems(OHS-18000) along with Environmental Management systems(ISO-14000) which are intended for achieving excellence in all areas where its people and stake holders are connected.The Corporation also embarked on a sophisticated Enterprise Resource Planning system in 2010 covering the whole ambit of mining operations throughout Gujarat to achieve efficiency and complete the tasks in time with the minimum resources required.
Lignite– GMDC owns four lignite mines -- Panandhro, Rajpardi, Mata-No-Madh and Tadkeshwar. In 2007-08 the production of lignite from these mines was 81,32,966 MT, 3,90,642 MT, 6,64,504 MT and 7,79,052 MT. Lignite, also known as brown gold, has applications in industries like textiles, chemicals, ceramics, bricks, captive power, etc.
Fluorspar- The company manufactures two grades of fluorspar namely acid and metallurgical.
Bauxite- GMDC owns two bauxite reserve located at Kutch and Jamnagar. Average total bauxite output is about one lakh tonnes per year.
Others projects- In 2001, the company entered into a MOU with RBW Minerals Industries for the production of clean concentrates, which shall be the raw material for different smelters elsewhere in the country for extraction of metals like lead, zinc and copper.
1963GMDC was incorporated in the year 1963 to develop major mineral resources in the state and commenced with a small silica sand quarrying plant near Thangadh to crush and screen the silica required for glass manufacturing. 1964Bauxite mining were commssioned as a scarcity work initiallly during 1964 at Kutch which was later expanded to six operating mines that produced refractory grade bauxite which was also suitable to metallurgical purposes. 1971In 1971, a beneficiation plant was commissioned to process 500 M.T of fluorspar ore and to produce calcium fluoride used for the maufacture of Hydro-fluoric acid and as flux in metallurgical industries. A captive mine at Ambadungar was established also to feed the plant. 1976The availability of lignite in the state was established which gave an oppurtunity for the Corporation to develop its first lignite mine at Panandhro in Kutch in the year 1976. The textile and processing houses benefitted in using the fuel which is competetive compared to coal. 1980A small pilot plant with a capacity to process 50 tons of multi-metal ore containing copper-lead and zinc was established at Ambaji in the year 1980. A captive mine was established and developed to supply to the plant at that time with a total metal content of about 10%. 1983A small lignite mine was also opened at Rajpardi in Bharuch in the year 1983 to cater to the industries located in south gujarat. 1988-89To develop the first lignite mine with advanced technological mining methods, the Corporation went ahead with the expansion plans by deploying continuous mines systems of Bucket Wheel Excavators at a total cost of 100 crores in the year 1988-89. 1992As a value addition to bauxite mining, the Corporation commissioned in 1992 a calcination plant at Gadhsisha in Kutch with a capacity to produce 50000 tons of calcined bauxite which is a major raw material for refractory products. 1996To mainly use the Kutch lignite resources, the Corporation established a 250 (125 X 2) MW thermal power plant at Nani-Chher in Kutch with circulating the fluidised bed cumbustion technology (CFBC). Tendering was done in 1996 with an investment of about 1400 Cr. 1999To bring in efficiency and profitability in all areas of its working, the government of Gujarat being the sole owner dis-invested 26% of its stake and the Corporation became a listed entity (BSE&NSE) in the Corporate world in the year 1999 and is occupying a position within the top fortune 500 companies in our country with an annual turnover surpassing 1000 Crores with considerable annual growth rate. 2002A Corporate office at Ahmedabad with an eight storied building was constructed to house all the departments and occupied the building in the year 2002. 2005-06A small lignite mine at Tadkeshwar in Surat district was also established during 2005-6 to cater to the industries located in south Gujarat. 2006-07The Government of Gujarat mandated the Corporation to develop the Manganese resources near Shivarajpur in Panchmahals. Hence a small project to handle the manganese waste was established in 2006-7. Simultaneously survey, exploration activities were initiated so as to develop a full fledged mine cater to the need of the metallurgical industry. 2008-09A lignite mine near Bhavnagar was established 2008-09 for the fuel supply to industries located the saurashtra region. By developing various lignite mines in the State, the Corporation became the largest merchant seller of lignite in the country. 2009The Corporation also went into harnessing the wind energy and commssioned 19.5 MW wind turbines near Malya in Kutch in the later part of 2009 which will be expanded further to the tune of 100 MW in various stages of implementation. 2010The Corporation first implemented ISO-9001 at Corporate office in 2010 and is planning to obtain for all the mines in operation with Occupational Health and Safety systems(OHS-18000) along with Environmental Management systems(ISO-14000) which are intended for achieving excellence in all areas where its people and stake holders are connected. 2010The Corporation also embarked on a sophisticated Enterprise Resource Planning system in 2010 covering the whole ambit of mining operations throughout Gujarat to achieve efficiency and complete the tasks in time with the minimum resources required.
2011: GMDC bagged the Best Maintained Public Places award.
