PREFACE

The booklet “ANCILLARY ACTIVITIES & SCOPE FOR MSEs IN M&R

COMPLEX” is a maiden venture by Materials Management Department of M
& R Complex. This booklet provides readymade information in brief on
different spares/materials used at Mines & Refinery, which can be developed
and supplied by Micro and Small Entrepreneurs. Though the information
available in the booklet are not exhaustive but may be of interest to the
entrepreneurs to start with.

This booklet contains the following information on each item:

1. Colour Photograph
2. Specification
3. Annual requirement with an approximate unit basic price

If desired, the MSEs can see these items in the Plants and further
discussions with the Users / Technical Departments can be arranged.

The booklet is also informative in brief on downstream industries &

service providing units those can be established by interested entrepreneurs
in and around Damanjodi for mutual benefit of the entrepreneurs and NALCO.

It has been the endeavor of NALCO, since inception, to expand it’s

vendor base and preference is always given to the entrepreneurs within the
state. With the various policies enforced by Government of India for
development of MSEs and the facilities extended by Nalco, it is felt that this
booklet shall be of help to the MSEs to be the business partners of this
Company.

 NALCO

National Aluminium Company Limited (NALCO), the Asia’s

largest integrated Aluminium Complex, in the Public Sector,
incorporated in 1981 encompassing Bauxite Mining, Alumina
Refining, Aluminium Smelting & Power Generation, Rail and
Port Operations. Commissioned during 1985-87, Nalco has
emerged to be a star performer in production, export of Alumina
and Aluminium, and more significantly, in propelling a self-
sustained growth.

The Bauxite Mines and Alumina Refinery Plant of NALCO

are situated at Damanjodi in Koraput District. The Smelter &
Captive Power Plant are situated in Angul District of Odisha and
the Port Facilities at Visakhapatnam, Andhra Pradesh.

 BAUXITE MINES

Bauxite is the primary raw material to produce Alumina. NALCO has

a fully mechanized open cast Bauxite Mines on Panchpatmali hills of
Koraput District of Odisha having a capacity of mining 63 lakh tons per
annum, which serves to feed stock to Alumina Refinery at Damanjodi. The
transportation of bauxite is done through a 14.6 Km long variable speed,
single flight, multi-curve, cable belt conveyor. The capacity of the
conveyor is 900 to 1800 Tons Per Hour. The bauxite received at Refinery
is processed to produce Alumina Hydrate and Calcined Alumina.

ALUMINA REFINERY

The Alumina Refinery Plant of NALCO is situated in the picturesque

valley of Damanjodi. The energy efficient Refinery Plant has four parallel
streams of equal capacity. The annual production capacity of the plant is 21
lakh tons.

The Refinery is designed to feed Alumina to NALCO’s Smelter Plant at

Angul & exports the balance Alumina to overseas markets through
Visakhapatnam Port. Alumina is transported through Nalco’s own
dedicated BTAP wagons. In addition to above, a considerable quantity of
alumina is sold to the indigenous customers, which are transported by road.

3
 ALUMINIUM SMELTER

The 4,60000 TPA capacity Aluminium Smelter, located at Angul in

Odisha, is basd on advanced technology of smelting and pollution control.
The plant manufactures Ingots, Sows, Billets, Wire Rods, Strips and Rolled
Products, besides T.Ingot and Chequered Sheets.

CAPTIVE POWER PLANT

Close to the Aluminium Smelter at Angul, a Captive Power Plant of

1200 MW Capacity has been established for firm supply of power to the
Smelter. The coal demand of the Plant is met from a nearby mine of
Mahanadi Coalfields Limited. The plant is also connected with the State Grid
for sale of surplus power.

PORT FACILITIES
On the inner harbor of Visakhapatnam Port on the Bayof Bengal,
Nalco has mechanized storage and ship handling facilities for export the
Alumina and import of caustic soda. Nalco also exports metal from the ports
of Paradeep and Kolkata.

 SCOPE FOR MSEs IN DOWNSTREAM INDUSTRIES USING
NALCO’S PRODUCTS AND BY-PRODUCTS
Brief profiles of some of the possible downstream projects, utilizing Alumina, Fly
ash and Red Mud are given below;

1. Fused Alumina
Fused Alumina is used in the manufacture of abrasive, high Alumina
Refractory bricks.
(i) Capacity 5000 MT of Fused Alumina per annum
(ii) Project cost ` 4 Crores
(iii) Location In and around Damanjodi
(iv) Raw materials Alumina, bauxite etc.
(v) Employment potential 100

3. Fly ash based Products:

Fly ash bricks (Details shown separately in this booklet)
Fly ash based tiles

4. Red Mud Based Products:

Red mud Bricks can be produced using red mud as the major raw material
at Damanjodi
(i) Capacity 1 million bricks per annum
(ii) Investment ` 3 Crores
(iii) Location In and around Damanjodi
(iv) Turnover ` 0.6- 0.7 Crores
(v) Raw material Red Mud, Clay, Talc Powder
(vi) Major equipment & fuel Kiln & Coal
(vii) Employment potential 50

5. Lime Grit based products:

Fly ash bricks, Tiles & Other cement based products

6. Zeolite, Alumina hydrate, Spl. Grade Hydrate,SGA Based products:

Alumina Hydrate: For making Insulator, Alum

SGA: For making refractory bricks, Castables, Ceramic balls,

synthetic marbles, paints and pigments.

Spl Grade Hydrate: For making fire retardant builder materials.

Zeolite: Used as builder material for detergents. Brand like Tide and
Henkel use our product.
NOTE:
Nalco supplies Fly ash & red mud free of cost to the MSEs. Lime
grit can be supplied at a cost to MSEs for their Brick Plants.

99
 Scope for MSEs in Service Sector

(i) Fabrication, machining and repair workshops in the vicinity of Damanjodi

meeting requisite quality standards for attending to emergent repair jobs.

(ii) Motor winding shops

(iii) Tyre Retreading workshops in the vicinity of Mines & Alumina Plant.

(iv) Pump repair shop

(v) Pulley, Roller, Idlers & Polyrim manufacturing unit for belt conveyor

(vi) Automobile and Earth moving equipment repair shop.

(vii) Repair of Air-conditioning equipments, maintenance and supply of spares.

100
 SCOPE FOR MSEs FOR PRODUCTION OF FLY ASH BRICKS
Fly Ash Bricks can be produced by utilizing the ash generated in Steam & Power Plant (SPP)
at Alumina Refinery, Damanjodi. This is an economically viable project.
(i) Capacity 5 million bricks per annum
(ii) Investment `30 lakhs
(iii) Location In and around Damanjodi
(iv) Raw materials Fly ash (60%),Sand(30%),Lime grit(5%), Cement
(5%)
(v) Electrical Energy 50 KWH (For 1000 bricks)
(vi) Employment potential 20 to 25
For the above plant, Fly Ash can be supplied by Alumina Refinery Free Of Cost.
Features
Some of the attributes of fly ash bricks are as follows:
» Eco friendly
» Low water absorption
» Dimensional accuracy
» High compressive strength
Advantages of Fly Ash Bricks:
Less Energy Consumption: Much energy is consumed in firing clay bricks in kilns. By using
fly ash bricks instead of clay bricks, much energy is saved in brick manufacturing.

Reduces air pollution - Fossil fuel is used in heating clay bricks in kilns. Burning such fuel
generates air pollution and greenhouse gas (CO2), contributing to global warming. Fly ash
bricks are manufactured at room temperature and there is no fossil fuel burning and emission
of green house gas (Co2).

High Strength: Due to high strength, there is practically no breakage during transport & use.
Due to uniform size of bricks mortar required for joints and plaster reduces almost by 50%.

Less Water Consumption: Due to lower water penetration seepage of water through bricks
is considerably reduced. Gypsum plaster (plaster of Paris) can be directly applied on these
bricks without a backing coat of lime plaster. These bricks do not require soaking in water for
24 hours. Sprinkling of water before use is enough.

Usage of Fly Ash Bricks: Because of above advantages, Fly Ash Bricks are getting preference
in construction works over the conventional clay bricks.
