This is an opencast mine producing iron ore. As such, no raw material from outside is

required for processing of iron ore. Run-of-Mine (ROM) from the mine is processed

to produce sized ore products. The ROM production during 2015-16 is 5.35 million

tonnes and during 2016-17 is 5.68 million tonnes.

Pollution discharged to environment / unit of output

a) Water Environment

Pollutants Quality of pollutants generated (mass/volume)

Concentrations of pollutants in discharges

Percentage of variation from prescribed standards with reason.

Standard

1. Process Effluent: The effluent generated from ore washing process is being treated in thickeners. The clear water from the thickeners is being recycled back and the under flow slurry is being discharged to the Tailings Pond. Though there is no direct discharge from the Tailing Pond, seepage from dam body is being discharged. The same is being monitored. The annual average quality of tailing dam seepage is follows:

(i) pH - 7.19 at 25OC 5.5 – 9.0 (ii) TSS - 5.80 mg/l 100 mg/l (iii) Oil & Grease - <1.40 mg/l 10 mg/l

2. Domestic Effluents : No Domestic effluents are discharged to Natural Streams. The

domestic effluent generated from the township is directed to Soak pits via intermediate septic tanks.

(i) pH - 5.5 – 9.0 (ii) TSS - 100 mg/l (iii) BOD - (iv) COD - (v) Oil & Grease -


b) Air Environment This is an opencast mine and the air emissions are fugitive in nature mainly containing dust particles. The fugitive emissions are being controlled through various dust prevention and control measures. Hence, the quantity of air pollutants discharged in Kg/day cannot be ascertained. The annual average ambient air quality in and around the mines for the year 2016-17 is given below:
