Minerals

The latest addition to PMC’s list of minerals is Garnet – Almandine. This is mined at PMC’s own Sri Venkata Sai Mines, located in Nellore Dist. AP. Almandine Garnet (sometimes wrongly referred to as Almandite) is twelve sided crystal. It is a very hard material with a Moh’s Scale hardness of 6.5 to 7.5.

This garnet is not got from beach sands like most other garnets in India and so is very eco-friendly. When garnet is mined from beach sand, large areas of the beach gets polluted and spoilt.Garnet is a very safe and eco-friendly material which can be used in various applications.

• Abrasives-Sand Paper, Cutting and Grinding Wheels.
• Sand Blasting -Cleaning and preparing of metal surfaces,Ship body Cleaning,Oil Refineries and out door equipment.
• Cutting -High Pressure Water Jet Cutting
• Water Filters-Water Medium
  

As a medium for sand blasting, Garnet is the preferred over Silica Sand, Quartz and metal slag. Garnet can be reused several and is non-polluting. And the fine dust produced during blasting is not carcinogenic like it is for Silica Sand or quartz.

Processing :

• The Garnet from the mines is cleaned with water to remove the mud and non garnet materials.
• These are ground in mills.
• Material is then sieved on vibro-sieves to get the required grain sizing.
• Finished product is tested in the lab and packed as per requirement.

We supply optimum quality of quartz  and Feldspar, the most common mineral on the face of the earth. These quartz mineral are found in different varieties and colors. Our range is best known for their durability and is widely used as a semi-precious gemstone. All our assortment of quartz minera is offered in white export grade.

The PREMICA™ range includes the following Silica Sand products, catering to the needs of the global market:

 AGGREGATES : Aggregates are a blend of two or more grades of sand having a different particle size distribution and characteristics. When these different types are blended in a correct proportion the resulting product will have a unique characteristic and a correct matrix of particles that provide extra strength and better troweling properties.These aggregates are used in seemless floorings systems.

COLORED : High grade silica sand is required in different colours for various applications such as floorings and decorative uses. PMC can provide a wide range of colours of artificially coloured sands.

GROUTS : Grouting has become a very technical and requires very specific grades of sand. PREMICA provides these very high specification grades of silica sand.

MOULDS : Very pure and clay-free silica sand is required to make moulds in the foundry industry. PREMICA grades of sand are most suited for this application

GLASS MANUFACTURE:The silica sand from the southern state Andhra Pradesh in India, where PMC sources its silica sand from, has been approved by the largest glass manufacturer in the world, due to its purity (Silica content - 99.8%). This same grade can be supplied by PMC.
