Our applications
Gypsum purification
Upgrade low grade or waste gypsum 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.
Chalk purification
Upgrade low grade or waste chalk to higher purity and whiteness
Other applications
Our process is proven to work on most products with a high level of calcium. Contact us to ask us about testing your feedstock.
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 use by phosphoric acid producers to produce higher purity gypsum as a by-product after separating the phosphoric acid from their phosphoric rock.
The CMP 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 in the final waste. This can be sold to specialist refiners to access the Rare Earth Elements (REEs).
Waste phophogypsum
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 (REEs) 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.
Test your feedstock
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.
