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.

The shovels used in RSMML mines are

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 .

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.

DRILL SECTION


14/22

DRILLING SECTION WORKING

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


15/22

Why Drilling is done ?

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.


16/22

DRILL ROD SIZE:

Length : 7.62mDiameter : 152mm (6)

Total drill depth : 30.48m (100)

Number of rods : Four

CRUSHING PLANT

Crushing is a process of converting rawmaterials to the required size of 12 mm.

In RSMM Ltd. there are two crushingplants:

Low grade ore crushing plant(LGO)

High grade ore crushing plant(HGO)


18/22

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 IBP 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.


19/22

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.


20/22

INDUSTRIAL BENIFICATION PLANT

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.


21/22

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 finalproduct.
