ABSTRACT
The objective of practical training at Post graduate level is to give a student an
experience of real issues involved in the business world. Practical knowledge helps
us to identify how theories can be applied in business life.
In this report, I have put in best of the information about “Ashapura Volclay Ltd.” on
a common platform, analyzed their production process, and highlighted the
company’s profile. Also I have put my understanding from the project given to me.

1.1 PROJECT
Primary Objective and Scope of Project
To understand Production Process of Bleaching Clay
The scope of this project contains details regarding the manufacturing process
of Bleaching Earth and Clay Catalyst, which is carried out under the
certification of ISO 9001:2008 Standard at Ashapura Volclay Ltd.

1.2 COMPANY PROFILE2
Established in 1960, Ashapura Group is India’s largest multi-mineral solutions
provider.The flagship company Ashapura Minechem Ltd. is listed on India’s premier
exchanges.Ashapura Minechem Ltd. is a part of the BSE Midcap & BSE 500 indices.
The group has mining & mineral processing facilities in Gujarat, Maharashtra,
Karnataka, Kerala, Andhra Pradesh and Orissa. Today Ashapura Group has attained
global status withprojects in Belgium, Nigeria, Oman and Malaysia.
Ashapura Group is one of the significant global players in bauxite and is amongst the
world’s top five Bentonite companies. Ashapura also dominates the value added
segments in the country for Bleaching Clay, Geosynthetic Clay Liners, Clay
Catalysts, Calcined Bauxite, etc.
Ashapura has advanced from being a single mineral company to a specialist in
industrial minerals. Bentonite, the multi-tasking mineral, continues to be a core
product with diverse applications in industries that range from agriculture to
environment and foundry to edible oils and cosmetics to medicine New applications
for the industries presently being catered as well as for new industries are developed
every year through indigenous and global research. The company’s diversification
into bauxite was a major move and today Ashapura is among the key players in
Bauxite from India. Our strategy to expand our mineral portfolio is paying rich
dividends as we have added Kaolin, Attapulgite, Barites, Feldspar and many other
allied minerals to our product portfolio.
A new exciting area, with immense growth potential and limitless possibilities,
opened when the company decided to move into value added products. At present
our major value added products are Bleaching Clay, Clay Catalysts, Geosynthetic
Clay Liners (GCL), Calcined Bauxite and very soon it will be alumina.
All products come with a promise of ‘No compromise on quality’.

ANALYSIS AND INTERPRETATION
Bleaching Earth1
Bleaching Earth is manufactured from the best quality, selectively mined and
scientifically blended montmorillonite
making Bleaching Earth special care is taken in maintaining the important properties
like absorptive capacity, acid properties, catalytic properties, ion exchange capacity
and particle size distribution.
Bleaching Earth is manufactured by Dry process OR Wet process.
A Bleaching Earth is Activated adsorbent used for the general purpose of
Decolourisation of animal, vegetable mineral oils and waxes
Enhance stability of the Refined Oil.
Bleaching Earth is characterized by
High bleaching efficiency
Fast filtration rate
Low oil retention
Ability minimise the increase of free fatty acids
Removing impurities like soap & trace metals without affecting appearance,
flavour & nutritional properties of Oil
Important Points During Bleaching
Normally about 0.5%
vacuum during process which results in less oxidation & improvement in oil
colour.
Choice of Bleaching clay as per its characteristics.
The total acidity (titrable acidity) of clay is expressed as mg of KOH/g of
clay on a hot water extract.
The Moisture content of Earth is vital as activity of clay depends on the
evaporation of moisture from earth after its admixture with oil (15% max free
moisture is desirable)
Bleaching Earth is manufactured from the best quality, selectively mined and
scientifically blended montmorillonite clays under stringent process controls. While

Treatment with Acid Activated Bleaching Earth in post-bleaching step
removes traces of Nickel from hydrogenated oils (0.25-0.5% of earth used).
Oil Loss During Bleaching Process:
Spent Earth carries around 30% of oil on dry basis. By hot water washing of filter
can be brought down to 22% on the average. So loss of oil is
approx. 8% during the process.

Bleaching Earth - Oils1
Cooking oil is purified fat of plant origin, which is usually liquid at room
temperature (saturated oils such as coconut and palm are more solid at room
temperature than other oils).
Some of the many different kinds of edible vegetable oils include: olive oil, palm oil,
