It is then fed into the centrifuge, where the crystals of Magnesium Sulphate are

separated from the mother liquor. The mother liquor is taken back to the reactor for the

next batch. Water is pumped to the settling tank and the impurities left in the settling

tank are leached 4 or 5 times with water till it is free from Magnesium Sulphate. Then

it is filtered through a filter press and stored in weak solution tanks. The filter cake

obtained in the filter press is dried in the drying yard along with the un-reacted ore

removed from the settling tank periodically, pulverized, packed, stored and sold. The

Magnesium Sulphate crystals obtained from centrifuge is packed and dispatched, or it

is dried in the MgSO 4 drying yard and packed depending upon the requirement of the

buyer.

Reactor

The main reaction for the manufacture of Magnesium Sulphate takes place here. The

reactor is a circular M.S. tank with a dia. of 3M and a height of 4M placed at a height

of 2M above the ground level Reactor is fitted with an agitator, gear box & electric

motor. Fresh water, mother liquor and weak Magnesium Sulphate solution obtained

from the mud washers are taken to the reactor. Required quantity of LCM (MgO) is

added-Spent Sulphuric acid from the measuring tank is slowly added into the reactor


18/133



Settling Tank & Weak Liquor Storage Tank

Settling tank is a M.S. tank of 12.5 KL capacity with a size of 2 M x 5 M x 1.25 M.

This tank is used to store the impure MgSO 4 coming from the reactor.

The weak liquor storing tanks are made up of M.S with diameter of 2.4 M and a height

of 2.5 M. These tanks are used to store the weak MgSO 4 solutions.

Crystallizers

These are again made up of Mild steel and are half cylindrical at the bottom and

rectangular at the top. It is provided with stirrers for constant stirring.

Hot concentrated solution of Magnesium Sulphate from the filter press is drained intothese and is allowed to cool slowly to room temperature with constant stirring, when

crystals of MgSO 4 are formed. When the solution reaches the room temperature which

it normally does in 24 hrs it is drained into the centrifuge.

Centrifuge

This is used to separate the crystals of MgSO 4 present in the solution drained from

Raw Material Section:

Main raw material rock phosphate is available in the form fine powder / coarse chips. The

proposed plant is based on the use of fine powder, which is shipped and stored in loosecondition in the go down. The go down is land yard having retaining walls on both sides.

Rock phosphate is heaped in the yard. A hopper and conveyor will be provided in the go


24/133



Acidulation Section

In this section processing takes place. This section consists of mixer and den (Main &R.P.) and acid feeder. The mixer is a horizontal blending machine having mixing and knee

ding section. Ground rock phosphate and dilute Sulphuric acid is continuously fed into

Mixer in fixed proportion. Due to continuous agitation by rotating paddles. First two stage

of reaction take place over here and the mass is converted into thick slurry. A particular

temperature and suction is maintained over here, for proper reaction. The slurry is

discharged by mixer directly into the other slow moving machine called den. Den retains

the slurry for advancement of reaction. Retention time of material in this section can be

changed based on the process need. A slow speed cutter is installed at the discharge end of

den. The den cutter chops the solid material into fine pieces, before discharging it from

den. The material is discharged by den continuously & slowly up to 85-90 % of reaction is

completed at this stage.

The material being discharged by den is Green Super Phosphate. The balance reaction

continues & is completed slowly, in heap in next few days. Den discharged is shifted &

heaped in Curing yard. The material is directly discharged over rubber conveyer. A set of

conveyer belts is installed in go down for shifting heaping of Green Super Phosphate at

different location in go down for curing. The Green Super reshuffled 2 to 3 times & cured.

25/133



Curing and Storage

The semi-finished goods, Green Super Phosphate will be kept in green SSP curing yard.

The material is directly discharged over green super belt, be den A set of cross and

inclined belt conveyors is installed for conveying the discharge of green super belt over

the shuttle belt conveyor. The shuttle belt is used for heaping green super Phosphate at

deferent locations in curing go down. The green super is reshuffled 2 to 3 times and cured

with in 12-15 days.

Cured material is heaped and checked for quality after approval from QCD material

required for captive consumption is shifted to N.P.K. plant/granulation plant or powder

packing section.

Product Packing Storage & Shipment

The material for direct sale as single super Phosphate in granular or powder from is further

processed material is shifted to granulation plant for converting the powder into granules

of desired size and packed in HDPE bags and kept in go down for dispatch to dealers.

Material to be sold in powder from is screened in a rotary screen and fine powder is fed

into packing hopper for packing. The oversize grid is shifted to granulation plant for use

after crushing in chain / hammer mill.


26/133



Pollution Control

In Process:

During acidulation fluorine content of rock phosphate is evolved as SiF4 gas. Fluorine

bearing gases are evolved during the reaction are to be removed before discharge to

atmosphere. The gases evolved during reaction in mixer and den is sucked by a high

suction blower & is scrubbed in circulating water. This section consists of H.V. jet

scrubber, Ventury scrubber, cyclone separator, I.D. fan & Chimney for sucking the gases

from point of generation & discharging to atmosphere at height of thirty Five meter, from

ground level after due cleaning. All the specially designed equipment of the section is

lined with different anti-corrosive materials. This scrubber liquor, namely H2SiF6, is kept

in lined pits for settling. The solid silica in the liquor is separated here & kept. The clear

liquor is kept in storage tanks & is used in process for manufacturing of Green SuperPhosphate.

The H 2SiF 6 liquor can also be used for manufacturing other Fluorine based chemicals,

such as Sodium Silico Fluoride. The silica can be sold or used as filler after sun drying.

As the liquor generated is recycled & used in process hence there will not be any liquid

discharge from the plant.

CHAPTER 3 DESCRIPTION OF THE ENVIRONMENT

3.1 BASELINE ENVIRONMENTAL STATUS

The baseline status of the environment quality in the vicinity of the project site serves as

the basis for identification, prediction and evaluation of the impacts. The baseline

environmental quality is assessed through field studies within the impact zone for various

components of the environment, viz. air, noise, water, and land and socio-economic. The

baseline environmental quality has been assessed in the winter season (December 2010

February 2011) in a study area of 10 km radial distance from the project site.

Knowledge of baseline environmental status of the study area is useful for Impact

Assessment Process of assessing and predicting the environmental consequences of the

significant actions. Significant action depicts direct adverse changes caused by the action

and its effect on the health of the biota including flora, fauna and human being, socio-economic conditions, current use of land and resources, physical and cultural heritage

properties and biophysical surroundings.

Baseline data generation of the following environmental attributes essential in EIA studies

have been studied and included in the report.

1. Meteorology

2. Ambient Air Quality


35/133



3.2 ESTABLISHMENT OF IMPACT ZONE

Deciding whether a proposed action is likely to cause significant adverse environmentaleffects is central to the concept and practice of EIA. Before proceeding for baseline data

generation, it is important to know the boundary limits and framework, so that the data

generated can be utilized for the effective and accurate prediction of the environmental

impact assessment of the proposed project.

3.3 METEOROLOGY

Air borne pollutants is dispersed by atmosphere motion. Knowledge of these motions,

which range is scale from turbulent diffusion to long-range transport by weather systems,

is essential to simulate such dispersion and quality of impacts of air pollution on the

environment. The purpose of EIA is to determine whether average concentrations are

likely to encounter at fixed locations (Know as the receptor), due to the given sources

(locations and rates of emission known), under idealized atmospheric conditions. It is

imperative that one should work with idealized condition and all analysis pertaining to air

turbulence and ambient air or noise pollution should be done with meteorological

conditions, which can at best be, expected to occur.

3.6 AIR ENVIRONMENT

3.6.1 Design of Network for Ambient Air Quality Monitoring Locations

The air quality status in the impact zone is assessed through a network of ambient air

quality monitoring locations. The tropical climatic conditions mainly control the

transport and dispersion of air pollutant emissions during various seasons. The baseline

studies for air environment include identification of specific air pollutants prior to

implementation of the project. The Environmental Impact Assessment (EIA) study

requires monitoring of baseline air quality during one season. Accordingly, air quality

monitoring was carried out in the winter season from Dec. 1, 2010 to Feb. 28, 2011. The

baseline status of the air environment is assessed through a systematic air quality

surveillance programme, which is planned based on the following criteria:

Topography / terrain of the study area Regional synoptic scale climatologically normal Densely populated areas within the region Location of surrounding industries Representation of regional background Representation of valid cross-sectional distribution in downwind direction

The dust laden gases enter the pre- separation plenum

1. Where they meet the low baffle plate

2. The baffle wall protects the sleeves against the direct flow. The air velocity isreduced in the pre- separation plenum. The coarse dust fraction leaves the airflow and falls into the dust collection hopper.

3. The gas laden with the fine remaining dust enters the filter plenum.

4. After deflection by the baffle plate.

5&6. The sleeves (6) fitted over supports (5) receive the flow in the outside. The finedust is deposited on the outside of the filter sleeves.

When the diaphragm valves have closed, the cleaned filter sleeves are onceagain ready for the normal filter process. All rows of sleeves are cleaned in afixed sequence. The cleaning time is so short that practically always the wholefilter surface of the filter is available. Moreover the necessary compressed airquantity in relation to the flow volume is the same up- and down- line of thefilter.The compressed air impacts are controlled by an electronic timer. Impactedregularity can be continuously set with the electronic timer, depending on thetype and amount of dust.

3.7 WATER ENVIRONMENT

3.7.1 Design of Network for Water Sampling LocationsThe water quality status in the impact zone is assessed through a network of water quality sampling

locations. The baseline studies for water environment include identification of specific parameters

of the pollutants prior to implementation of the project. The Environmental Impact Assessment

(EIA) study requires monitoring of baseline water quality during one season. Physico-chemical

parameters have been analyzed to ascertain the baseline status of fresh water in the existing surfacewater and ground water bodies. Samples were collected once during the study period for winter

season on December 2010 & February 2011.

The baseline status of the water environment is assessed through a systematic water quality

surveillance program, whic
