Presence: DTC has selected to grow its presence in Jharkhand, the most mineral-rich state of India.
Minerals: DTC principally mines four products - China clay and silica sand; graphite and granite (stone chips).
Focus: DTC mines niche minerals that are subsequently processed and beneficiated
Companies: DTC's mining business is conducted through its sister concern - Rajmahal Quartz Sand & Kaolin Co. (accredited with ISO 9001:2008).
Intellectual capital: DTC possesses a deep experience of more than 25 years in the mining sector. The result is an insight in untapped mineral segments.
Technology: DTC has invested in heavy chain-mounted excavators and their transportation is done by high capacity dumpers, an integral part of our commitment towards environmental conservation. GPS surveys are used to indicate optimal locations for conducting mining activities. The processing unit has been fully automated to deliver qualitative consistency.
Customer base: DTC addresses a broad customer base comprising of Bokaro Steel Plant, Heavy Engineering Corporation, Electrosteel Castings Limited, Bharat Heavy Electricals, Aditya Birla Insulators, Insulators & Electricals and Hindustan Sanitaryware.
Factory and mines: Rajmahal, Manghalhat Hills, District Sahibgunj, Jharkhand
Mines: Rajmahal Quartz Sand (RQS) operates two mines spread over areas of 10, 80,000 square feet and 26, 06,400 square feet respectively in Jharkhand.
Factory: RQS processes the material received from its mines at its own unit to beneficate and add value to the product. Through its automated process RQS has been able to provide high grade China Clay and Silica Sand as per the requirement and specification of its customer.
Applications: China clay is used in the manufacture of ceramic and pottery; the white variety is used in glazing. Silica sand is used in the iron and steel and glass sectors as it provides SiO2 for glass formulation.
Product mix: RQS produces silica Sand, customised according to the grain size requirements of customers, making it the sole entity to do so. The high durable china clay enhances end-product strength resulting in premium realizations.
Capacity: The Company is optimistic about increasing the capacity from present 1, 00,000 tonne to 1, 50,000 tonne, annually.
Customers: RQS' principal longstanding silica customer is Bokaro Steel Plant; recently RQS bagged an order from Bhilai Steel Plant. RQS is the sole supplier of china clay to prominent pottery and insulator users' pan-India.
Mines: Mahugain, Tulbula, District Bishrampur, Jharkhand
Nature of mines: It is in partnership with Jharkhand State Mineral Development Corporation
Applications: Due to stability at high temperatures and chemical inertness, graphite is used in the production of refractory bricks and production of 'Mag-carbon' refractory bricks (Mg-C). Graphite is also used to manufacture crucibles, ladles and moulds for containing molten metal. It enjoys an extended demand in the nuclear, electrical and stationery sectors.
Quality: DTC is planning to invest in world-class technologies to further beneficiate the graphite quality. It intends to make graphite with a purity of 99.9% from its unit.
Value-addition: DTC intends to enhance value-addition of materials to address the demanding needs of customers.
Category: DTC mines have been classified as A-grade by Jharkhand Mineral Development Corporation, validating its superior mineral quality. The mines are equipped with two high quality ores - amorphous and flaky, with high percentage of recovery from the ores.
Capacity: DTC plans to invest considerable amount to modernize the mines and construct a processing unit (200,000 TPA) to enhance extracted material from the mines.
Mines: Taljhari, Barharwa, Jharkhand
Capacity: DTC intends to commission two stone processing units (Taljhari and Barharwa) across leased 25 acres each. A crushing unit at each location (200 tonnes/hour) is proposed.
Technology: DTC intents to invest in VFI technology to in line with NHAI requirements. It intends to implement washing technology to use waste dust from crushing units to manufacture M-sand used in the construction industry.
New opportunity: M-sand, used in construction, is a river sand substitute that can potentially counter environment degradation.
Application: The stone chips are utilized mainly in building roads, dams and other civil projects.
Scope: The governmental has targeted 1 trillion USD investments in the country's infrastructure sector in the Twelfth Plan.
