Matasukh-Kasnau mines are situated near villages Kasnau & Matasukh of Nagaur district in the central Rajasthan, which is 42 Km from district head quarter. The commercial production of Lignite from these mines, was commenced from November 2003 with envisaged capacity of 12,00,000 MT per year. These mines are located in central part of Rajasthan, thus having better accessibility to markets in Uttar Pradesh, Haryana and Punjab. Lignite of these mines has added advantage of low sulphur and ash contents.
LIGNITE & ITS APPLICATIONS
Lignite, a premature variety of coal is a dark brown to black combustible mineral formed over millions of years by the partial decomposition of plant material subject to increased pressure and temperature in an airless atmosphere. In simple terms, lignite is a brown coal. In its natural form, lignite is porus, light in weight and contains a high percentage of moisture and volatile matters as compared to Fixed Carbon. Because of this, its transportation, over long distances is uneconomical. Therefore, this fuel is ideally suitable for running Lignite based power generation plant located close to pit head.
Mining Lime Stone
SANU LIMESTONE UNIT, JAISLAMER
High quality Limestone is a technological necessity for Steel Plants with the basic oxygen furnance technology where it is used as a flux. After the closure of limestone quarries at Dehradun by the historic judgment of the Hon’ble Supreme Court the limestone from Jaisalmer found enormous importance in thev Steel Industry. It was the recommendation of the technical team constituted by Govt. of India in the year 1986 after assessing the various limestone deposits available in the country that the low silica limestone available from Jaisalmer is the best suited for use in the Steel Industry. Based on the recommendation mining of Limestone was commenced by the company since 1988 for supply to different Steel Plants from their mines at Sanu. Jaisalmer limestone is best suitable for use in Steel Industry because of low silica and high decrepitation index. Hence the total production is dispatched to various Steel Plants of SAIL and TISCO. The company is the largest producer & supplier of steel grade limestone in the country.
This high grade, low silica, hard compact limestone is available in Khuiyala formation of Eocene age of Tertiary period. The company have around 20.00 square KM area near village Sanu at a distance of 56 Km from Jaisalmer on Jaisalmer – Ramgarh road & is well connected with all weather tar road maintained by Border Road Organization. The total mineral reserves under the areas held with the company are167 Million Tonnes of S.M.S grade limestone & 2153 Million Tonnes of Cement grade limestone. Company has enhanced its mineral reserve status by applying few more areas in the same belt.
LIMESTONE UNIT, GOTAN
Limestone Unit, Gotan is located near Village Gotan District Nagaur of the State Rajasthan. It is 90 kms. from Jodhpur. It is well connected with rail link on Jodhpur-Jaipur Broad Gauge Line.
The limestone deposits of Gotan are a part of the famous Sojat-Bilara-Nagaur limestone belt of Vindhyan Supergroups. Mining of limestone at Gotan was started by company in the year 1974.The company has three leases in the name of Gotan-I, Gotan-II & Basani with total area 4915.18 hects covering mines of Heera, Sawai,Sona, Dhanappa, Kerli, Keria, Ganthiyala & Pawani. These mines are around 10 KM from Gotan. The limestone deposit of Sawai-Heera & Sona mines of Basni lease are considered to be the best available deposit in the entire Sojat-Bilara-Nagaur belt. The deposit contains very low silica, high calcium and moderate decrepitation index. All the grades of limestone is produced from these mines & supplied to steel plant, chemical plant, white & gray cement plant & local kilns of limestone.
Mining is carried out by mechanized two bench opencast mining method, deploying HEMM and deep hole blasting. Sizing & loading is carried out by manual means. The company is planning to commission its own sizing & screening plant at mines of the capacity 40 TPH during current financial year 2005-06. The different size products are dispatched FOR mines as well as by rail from Gotan Railway sidings (BG).

Mining – Gypsum
We are the country’s leading producer of natural Gypsum and Selenite producing about 1.0 million tonnes per year. These are mined in the heart of the Thar desert areas where the working conditions are very harsh. The deposits are shallow and scattered over large areas. Most of the land is owned by private cultivators.
The mining of Gypsum of purity of +70% CaSO4, 2H2O is a co-operative effort between the land owners and RSMML. The farmers gives up his gypsum bearing land to RSMML in return for an assured share of profits. After mining, the Company improves the land condition and returns back to the farmer for cultivation.
Beneficiation
Looking to the scarce rock phosphate resources in India, RSMML has put continuous effort for utilization of its low grade ore resources, which are abundant at Jhamarkotra but require beneficiation before its utilization by fertiliser industries as raw material. Intensive research was carried out for ten years and a breakthrough in processing technology was achieved when this LGO was enriched to produce a very high-grade concentrate (+34%P2O5), rated as equal to or better than any naturally occurring ore. From reserves conservation point of view RSMML has put up a beneficiation plant for processing of 9 Lacs MT of low-grade ore per annum0
Wind Power
With a view of diversification activities and to protect environment degradation, RSMML has entered into wind power generation business in 2001. RSMML has commissioned 14x350Kw wind energy turbine on 70 mtr. high lattice towers at Badabagh area of Jaisalmer. The wind farm at Badagarh was expanded with additional 14x350Kw WET's in May 2002. In 2004, RSMML has commissioned 4x1250Kw WETs in Pohra Village of Jaisalmer. 6x1250 Kw (7.5 MW) was added in March 2006. In current fiscal year 25x600 KW (15 MW) wind farm is installed at Bharmsar- Pohra at Jaisalmer. Now the total wind farm capacity of RSMML is 37.3 MW. Annual Generation of grid quality power is now 665 lacs Kwh from echo friendly windpower. Further Company is in process of setting additional 15 MW windpower in 2007.
Bio Deisel
The vision of Hon’ble Chief Minister, Rajasthan, Smt. Vasundhara Raje for developing the vast degraded waste-land of Rajasthan as a viable resource for generating renewable energy by cultivating Jetropha curcas (Ratanjot), inspired RSMML management to explore the possibility of putting up a Jetropha based bio-diesel pilot plant in Jhamarkotra Rock Phosphate project, Udaipur, as a part of company’s continuing quest for better environment management.
Udaipur division is naturally endowed with wild Jetropha groves with pockets, yielding good quality seeds. However, to encourage farmers to plant Jetropha on large scale, confidence about getting reasonable price and assured market, need to be built up. RSMML management adopted a strategy of end product driven growth, in which farmers will directly feel the marketability and quality of the end product, i.e. superior bio-diesel used in mining machinery (thereby creating a strong and permanent demand) which would encourage them to plant more trees. Being critically dependent on seed price, better production economies of bio-diesel can only be achieved if seeds are available aplenty at a support price remunerative to the supplier villager.
RSMML and other mining companies consume huge quantity of fossil fuel for mining operations. Partial replacement of such petro-oil by bio-diesel will open up effective rural employment on a major scale and will also help in reducing pollution.
Plantation of Jetropha will also take care of greening of mined out land in the leases of the companies.
Management of RSMML was aware that Central Salt & Marine Chemicals Research Institute, Bhavnagar, Gujarat, (A CSIR Laboratory), in association with Daimler Chrysler had carried out a road test of bio-diesel, derived from Jetropha by using one E-220 CDI Mercedes car in April, 2004. The test was reported to be a success. Shri R.K.Mishra, IAS, MD, RSMML visited CSMCRI in April 2004 and formulated the project after discussion with Director, CSMCRI. 3000 kg of wild Jetropha seeds from Udaipur were sent to CSMCRI laboratory for producing bio-diesel
RSMML also used 368 litres of neat bio-diesel for running a 850 HP HEMM (85T BEML make dump truck) for 4.7 hours on a test mode. Again, the performance exceeded expectation. The company also arranged for the testing of bio-diesel so received from CSMCRI at Bharat Earth Movers Ltd., Bangalore (a Central PSU) for an independent evaluation. BEML submitted a detailed report based on short run testing of the sample sent by RSMML and concluded that the results were satisfactory.
Research by Daimler Chrysler shows that, though heat value of bio-diesel is 15% less than HSD, yet there is minor reduction in mileage.
The board of RSMML approved to set up a pilot bio-diesel plant with 1 TPD seed processing capacity (260-270 Lt. Bio diesel per day) to evaluate the economics of operation and to get familiar with the technology
RSMML has already consumed 2350 Kg. (valued at Rs. 24/Kg.) of soap in the rock phosphate beneficiation plant. The oil cake will be sold in the market for production of bio-fertilizers. There are already several commercial enquiries for oil cakes received by the Company. Glycerin and Potassium Sulphate are high value by-products, which will be sold after considerable accumulation.
Taking into account all factors, the cost of production of high quality bio-diesel is around Rs. 27.50, at a cost of Rs. 7/- per Kg. of seed.
RSMML has also distributed 2.5 lakhs saplings of Jatropha plant procured from Forest Department in all Panchayat Samities of district Udaipur, free of cost.
RSMML has ambitious plans to enter into large scale plantation of high yielding variety of Jatropha Curcas in association with Biodiesel Authority of Rajasthan, Forest Department and local village Panchayats. The pilot plant has given enough exposure in terms of production methods, quality of bio-diesel, its test in real time and dynamics of production economics. RSMML’s experience will be helpful for Government to decentralize production of high quality bio-diesel synchronized with local collection of wild seeds in a number of tribal panchayats.
