2.  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.
 Mining and basification of low grade rock phosphate to
produce high grade rock phosphate concerned at its IBP at
Jhamarkotra , Udaipur.
 Manufacturing and selling of low grade ore as phosphate
fertilizer called RAJPHOS for direct application.

3.  VTC is the training centre 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.  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 .

10.  Dumpers are used for the transportation
purpose of raw materials.
 Dumpers unload the raw materials to the
dumping yard ,IBP and crushing plant.
 Each dumper costs more than 3 crore .
 Currently there are 15 dumpers in the
RSMML.
 Tubeless tires are used in dumpers.

16.  Drilling on hole is the most important
operation in open cast mine. There are
three types of drilling machines and two
compressors are available.
 Types of drilling machines:
1. IDM-45D - 8.5” dia
2. IBH-10 - 6” dia
3. ICM-260 - 4” dia

17.  Firstly particular site is examine for drilling.
 After drilling is done blasting bombs are
inserted in the holes.
 After this procedure blasting takes place and
the material is loaded to dumpers by the
shovels.
 These materials then send to crushing plants
for further reducing in dimension nearer to 25
mm of size.

19. :
length : 7.62m
Diameter : 152mm (6”)
Total drill depth : 30.48m (100”)
Number of rods : Four

21.  In RSMML ltd there are two
crushing plants:
(a) Low grade ore crushing
plant(LGO)
(b) High grade ore crushing
plant(HGO)

22.  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 IBP plant.
 In LGO plant cone crusing and double
face jaw crushing are used.
 Then the final product is dumped in the
dumping yard and then sold in the
market.

23.  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.

24.  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.

25.  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.
