EIA/EMP Report of Beneficiation Plant –BRPL
transportation system design criteria. The concentrate shall also have
approximately 80% of (-) 325 mesh (- 45 micron) material and a nominal grade
of 64.5% Fe to meet the pellet plant process requirement.
Two identical beneficiation circuits, each with a capacity to produce 2 mio tpa of
iron ore concentrate are envisaged. Beneficiation process consists of:
• Primary wet grinding;
• Hydro cycloning;
• Two stage spiral classification;
• Single stage high gradient magnetic separation;
• Regrinding and thickening of concentrate received from both spirals; and
• Magnetic separators.
The details of main machinery/equipment envisaged for the proposed beneficiation
plant are as per given below:
Sn Particulars Quantity Capacity
1 Primary ball mill 2 330 tph (each)
2 Primary Hydro cyclone (26” dia.) 10 100 tph (each)
3 Primary spirals 308 starts -
4 Cleaner spirals 228 starts -
5 Secondary Hydro cyclone (10” dia.) 20 50 tph (each)
6 Regrinding ball mill 2 230 tph (each)
7 Linear screen 2 151.5 tph (each)
8 Cone splitter 2 28 tph (each)
9 HGMS 2 137.5 tph (each)
10 Intermediate Thickener (55m dia.) 1 303 tph
11 Concentrate Thickener (48m dia.) 1 558 tph
12 Tailing Thickener (60m dia.) 1 98 tph
13 EOT crane (Ball mill Bay) 2 60t/10t
14 EOT crane (HGMS Bay) 2 12t/3t
� Power
Total power requirement during operation phase of the proposed beneficiation
plant shall be 18.5 MW which is proposed to be obtained from the North Eastern
Electricity Supply Company of Orissa Ltd. (NESCO). One standby Diesel
Generator having a capacity of 750 KW is envisaged which shall be used in case
of power failure only.
