industrial training of 30 days at rsmml, jhamarkotra udaipur, for ece students.

1. Bachelor of Technology In the Department of Electronic & Communication Engineering Summer Training 2023-2024 at RAJASTHAN STATES OF MINERALS AND MINES LIMITED Duration:14 June to 13july,2024 SUBMITTED TO : SUBMITTED BY: Dr Navneet Agrawal Head Of Department Electronic And Communication Engineering Nandinie Jhala III YEAR (ECE)

2. CONTENT Introduction to RSMML and the Jhamarkotra site VTC Department and Power Plant operations Shovel Section and Industrial Benefication Overview of the Instrumentation Department Projects undertaken and skills acquired during the internship Conclusion and future aspirations

3. Company Overview RSMML is multi mineral and multi location enterprise engaged in mining  of Rock Phosphate The company is mainly responsible for the production of rock phosphate. The very objective of the company is to achieve cost effective technological innovations in the mining of minerals. Company is focused about mining and marketing of high grade rock phosphate ore at Jhamarkotra , Udaipur, , Largest rock phosphate mines in India. Mining and basification of low grade rock phosphate to produce high grade rock phosphate concerned at Jhamarkotra , Udaipur. Manufacturing and selling of low grade ore as phosphate fertilizer called RAJPHOS for direct application.

4. VOCATIONAL TRAINING CENTRE VTC is the training center which provides safety training to every member of the company. In this section training officer provides complete detail about the company. In this centre training is provided by Engineers or the managers of the company so that workers can work efficiently in their respective working areas.

5. LOW GRADE ORE CRUSHING PLANT Obtain from open cast mines. It contains 16% to 19% of phosphate. This low percent ore is made rich upto 34% of phosphate in an plant . In LGO plant cone crushing and double face jaw crushing are used. Then the final product is dumped in the dumping yard and then sold in the market .

6. HIGH GRADE ORE CRUSHING PLANT There are two HGO plants in RSMML. (1) Old crushing plant – capacity 120 tones/ hr , established in 1971. (2) New crushing plant- capacity 180 tones/ hr , established in 1992. It contains 34% of phosphate and can be directly sold to the market. Jaw crushers are used in HGO plant .

7. Shovel Section The shovels used in RSMML mines is hydraulically operated. After blasting the fragmental material it is loaded in to dumper by hydraulic excavators. It can load 10 to 12 dumpers in one hour. All shovels are of beml company and each costs above 3 crore

8. Industrial Benification The low grade ore which contain 16% to 19% phosphate is treated with some chemicals like phosphoric acid, sulphuric acid. Then it converted into high grade ore with 34% phosphate concentration. After this the output product is dumped in the dumping yard. From dumping yard these final product is loaded in the dumpers.

9. Industrial Benification There can be more than 200 products made from treating this final material with different ingredient and then they can be directly used. For final product the material is given to many small companies like Rama Phosphate etc. which makes final product .
