MINERAL PORTFOLIO

Gypsum

CaSO₄·2H₂O

CarboCore supplies gypsum for construction, cement, agricultural and industrial processing applications.

Gypsum begins with geology, but its value is proven in production. Egypt’s gypsum formed as ancient saline waters evaporated, leaving mineral-rich sedimentary layers across Sinai and the Gulf of Suez–Red Sea corridor. Origin alone does not decide performance. Purity, host geology, processing conditions and the final specification do. That is where every CarboCore order begins.

APPLICATION MATCHING

Matched to What You Make

Different requirements deserve different specifications. Tell us yours.

If you produce…	Your priority is…
Cement	Consistent purity, sulphate contribution and controlled moisture
Plaster and gypsum products	A stable raw material for reliable calcination
Decorative casting	Fine detail reproduction and handling strength
Wall plaster	Suitable working time and smooth application
Ceramic moulds	Controlled absorption and durability
Agriculture	Suitability for the intended use

PRODUCT FORMS

Two Forms. Two Different Jobs.

Natural Gypsum

Control starts with chemistry.

Natural gypsum keeps its chemically bound water. It is the mineral raw material for cement, plaster production and suitable agricultural uses.

Price per tonne is only the start. Purity, sulphate contribution, moisture and compatibility with your formulation decide whether a grade fits.

Calcined Gypsum (Plaster of Paris / POP)

Performance starts with processing.

Heating removes part of the bound water and creates a reactive binder that sets when mixed with water.

Whiteness and fineness are not the full story. Calcination conditions, particle characteristics and formulation shape water demand, working time, strength and dimensional stability.

IMPORTANT The values above are typical reference values published for initial buyer screening. They are not universal guaranteed limits. Current source/lot COA, approved sample, agreed specification and formal commercial quotation govern final acceptance.

Rock and lumps: Specify minimum and maximum size, with acceptable fines and oversize.

Ground material: Specify sieve residue or particle-size distribution.

Free moisture: Establish a separate acceptance limit; chemically combined water is part of gypsum’s mineral structure.

Whiteness: Confirm the required value and measurement method for appearance-sensitive applications.

Natural gypsum: Requires appropriate processing for plaster and board manufacture. Finished calcined plaster needs a separate specification, including setting and strength performance.

QUALITY ASSURANCE

Quality & Documentation

Request the Technical Data Sheet (TDS), Safety Data Sheet (SDS), and batch-specific Certificate of Analysis (COA) for the selected material.

Technical approval should confirm purity, sulphate content, impurities, free moisture, and sizing. The COA should identify the batch and distinguish tested results from specification limits.

PROCESS

How an Order Works

Tell us your application.

What you make and which properties matter most.

We propose the grade.

Matched to your process, not to a catalogue.

You receive a clear offer.

Specification, packaging and shipment terms defined upfront.

We coordinate shipment.

One point of contact until it reaches your port.

WHY CARBOCORE

Why Buyers Choose CarboCore

We start with your process.

Your application guides the selection, then we propose a product.

Specifications that mean something.

Chemistry, physical characteristics and processing behaviour are considered together, not a single purity figure.

Clarity at every step.

Requirements are defined before the offer, so technical and commercial evaluation is straightforward.

One commercial partner.

Egyptian supply, product selection and export coordination, handled together.

Applications are indicative and subject to the selected grade’s chemical composition, particle-size distribution, surface treatment and processing characteristics. CarboCore’s technical team supports customers in selecting the appropriate grade for their formulation and manufacturing process.

Food, feed, pharmaceutical, cosmetic, medical and potable-water applications require separately evaluated and approved grades. Compliance should not be claimed unless the relevant certification and regulatory documentation are available.
