Purifying calcium-based products

 

 

OUR

APPLICATIONS

GYPSUM PURIFICATION

 

Upgrade low grade or waste gypsum to higher purity and whiteness. 

CHALK PURIFICATION

 

Upgrade low grade or waste chalk to higher purity and whiteness

PHOSPHOGYPSUM

 

Process phoshogypsum to produce higher grade gypsum and concentrate any Rare Earth Elements (REEs) that are present in the phosphogypsum.

OTHER APPLICATIONS

 

Our process is proven to work on calcium-based mineral products.

Contact us to find out about processing your feedstock.

The process works 
at moderate temperatures

The use of acid or
other harmful reagents
is minimised

The reagents are widely available and are recycled
for re-use

Recycling waste products reduces the need for new gypsum mines

The process is relatively quick and does not involve costly equipment

Heavy transportation avoided if local lower grade feedstock can be sourced

Extracting rare earths from  concentrated residual phosphogypsum waste reduces the need for more mines

The process produces a higher yield, creating considerably  less waste so requires less waste storage

 

THE CMP

PROCESS

  • Reagent recycled

  • Tailor the degree of purity

  • Integrated or standalone

The Calcium-based Mineral Purification (CMP) process  reacts with impure calcium-based minerals with a reagent solution at a moderate temperature and pressure.

Contaminants can then be released and separated out of the reagent solution.

The product is then converted to purer, brighter chalk or gypsum and separated out of the reagent solution.

The reagent solution can be re-used.

USING THE CMP PROCESS

PURIFYING CHALK AND GYPSUM

The CMP process can be used on a wide range of chalks and gypsums to purify lower grade material to higher purity and brightness.

The output can be tailored to the market's requirements, and the process  integrated into your own plant and workflow or used as a standalone plant.

PURIFYING PHOSPHOGYPSUM

The CMP process can be used to purify phosphogypsum to produce gypsum which can be tailored to meet the market's requirements.

The process can be used standalone or integrated with the producer's own plant to maximise on efficiency and conserve energy and other resources.

With an increased yield of higher purity gypsum, feedstock waste is minimised.

It also concentrates the impurities, which can contain Rare Earth Elements (REEs), in the final waste for further processing.

WASTE PHOSPHOGYPSUM

Phosphogypsum waste is a multi-billion tonne waste and pollution problem. 

Due to the efficiency of the CMP process, it can be used to clean the waste to produce highly saleable high purity gypsum. 

As an extra benefit, if mineral-rich phosphogypsum is processed using the CMP process, the residual waste provides a concentrated source of rare earth elements which can be sold to specialist refiners. 

OTHER APPLICATIONS

The CMP process works effectively with a wide range of calcium-based materials, notably:

  • Chalk: Low quality natural chalk and waste chalk (lime mud)

  • Gypsum: Phosphogypsum, flue-gas desulphurisation (FGD) gypsum, citrogypsum, fluorogypsum, titanogypsum, waste incineration gypsum, mine tailings, water treatment sludge and natural mined gypsum.

INTERESTED? CONTACT US FOR TESTING AND ANALYSIS

We provide a range of services to help potential clients evaluate their options. Send us your calcium-rich samples for testing and analysis. 

We also offer in-house process R&D, client project evaluation, process design and consultancy and full assistance to the CMP process installation and commission. We welcome opportunities to discuss your requirements.

 

ENVIRONMENTALLY

SUSTAINABLE

The CMP process ​is designed to help refiners and processors of calcium-rich minerals minimise the over-use of natural resources and minimise waste while increasing the value and purity of their output.
