KMML Mineral separation unit

Hello sir, I am Pappu Gandhi. I am from Kerala. I want you to help me by giving me some information about the Kerala Minerals and Metals Limited (KMML), Mineral Separation Unit and its process. Can you help me?

As you have asked about the Kerala Minerals and Metals Limited (KMML), Mineral Separation Unit and its process, I am giving you information about it
The mineral-rich sands harvested from the captive beaches are first taken to the Mineral Separation Unit (MS Unit) where the separation of Ilmenite, Rutile, Leucoxone, Monazite, Silliminite etc from the beach sand takes place.

The MS Unit employs Gravitational, Magnetic, High tension electrostatic techniques for separation of minerals from the sand.

The Process at MS Unit is as follows:


Wet Concentration Plant

Beach washing sand having low grade heavy mineral content is
upgraded using spiral concentrators at various stages.

The concentrate thus obtained is washed with fresh water and
dehydrated using hydro cyclone

Dryer Plant

Fluidized bed dryer is used to remove the moisture and to maintain
sand temperature at 100 degree Celsius

Furnace oil is used as fuel for the fluidized bed dryer

High capacity fans are used for fluidization of sand

Dried concentrate is fed to dry mill

Dry Mill

Concentrate is separated into conducting and non-conducting fractions
by using high-tension electrostatic separators

Conducting fraction is further separated into magnetic (Ilmenite) and
non-magnetic fraction (rich in Rutile) by using magnetic separators

Non-conducting fraction is transferred to Zircon plant for producing
zircon

Non-magnetic fraction is transferred to Rutile recovery plant for the
separation of Rutile

Finished product of dry mill is Ilmenite

Rutile Recovery Plant

Non-magenetic fraction is processed at various stages using High
Tension Electrostatic Separators, Induced Roll Magnetic Separators and
seived in suitable mesh to produce specified quality Rutile.

Rutile is packaged in 50 Kg bags

Zircon Plant

Non-conducting fraction is fed through series of non-conductor cleaner
configuration High Tension /Electrostatic Separators fafter seiving with
suitable mesh for purifying non- conducting fraction

Air tables are operated to remove quartz and Sillimenite ifrom Zircon
rich sand

Zircon concentrate from air tables are fed through series of high
tension electrostatic / magnetic separators for the production of zircon

Zircon is packaged in 50 Kg bags
