Magnesite

Eskişehir’s white ore. From our own licensed site at Ballık to industry since 1994.

Ballık magnesite site · Tepebaşı, Eskişehiryildizmadencilik.com.tr

Bringing Eskişehir’s magnesite to industry since 1994.

Our company was founded on 6 June 1994 by Gürsel Yıldız and Murat Yıldız as Yıldız İnşaat ve Madencilik Ltd. Şti. Today we work the magnesite mine at Ballık, within Satılmışoğlu in the Tepebaşı district of Eskişehir, under our own licence.

Since 2010 we have supplied our magnesite to markets in Türkiye and abroad. Our aim is to keep improving production and beneficiation by following technological developments, and to keep raising our quality and capacity.

Our site

The Ballık magnesite site

Magnesite ore is taken as run-of-mine ore from the benched open pit on our licensed site. We manage the whole process, from crushing to shipment, on the same site with our own teams.

Location: Ballık, Tepebaşı / Eskişehir
Licence: Owned by the company
Method: Benched open pit
Ore: Magnesite (MgCO₃)
Markets: Türkiye and abroad, since 2010

The ore

What is magnesite?

Magnesite is a magnesium carbonate mineral. Fired into magnesium oxide (magnesia), it is the basis of the refractory materials that every high-temperature industry needs. 75% of the world’s sintered magnesia is produced from magnesite.

Formula: MgCO₃
MgO content (pure): about 47.8%
Crystal system: Trigonal (rhombohedral)
Hardness: 3.5–4.5 Mohs
Density: ~3.0 g/cm³
Colour: White, light grey

Production

From pit to product

Run-of-mine ore is processed on two lines by grain size. At the end of both lines, the product is hand-sorted by colour.

01
Open pit
Ore is taken from the benched open pit as run-of-mine.
02
Crushing
Run-of-mine ore is reduced to workable sizes.
03
Screening
Screens split the material into two lines: 2–10 cm and 0.5–2 cm.
04
Washing
A washing drum removes clay and dust.
05
Hand sorting
Our teams sort the ore by hand using colour.
06
Magnetic separation
On the fine line, impurities such as serpentine are held back.

Applications

Where does magnesite go?

It is the raw material of the refractories every high-temperature industry needs, and of many other industrial products.

FeSteel and metals
Basic refractories for ladles, converters and arc furnaces
Sinter
CaCement and lime
Heat-resistant linings in rotary kilns
Sinter
SiGlass and ceramics
Refractory linings for melting furnaces
Refractory
NAgriculture
Feed additive and fertiliser
Caustic
MgChemicals and pharma
Raw material for magnesium compounds
Caustic
CRubber, plastics, paper
Stabiliser and vulcanising additive
Caustic

Why strategic? A plant that cannot get its refractories on time has to stop production. That is why refractory raw materials are of strategic importance to basic industry.

Environment and sustainability

Respect for the land, value for people

With the water spray system in our pit and covered processing plant we keep dust to a minimum, and we are regarded as an example in site management and occupational health.

Dust control
Dust is suppressed at source with water sprays in the pit and plant.
Covered plant
Ore processing is done under cover.
Safety
Trained teams and protective equipment.
Local jobs
Work for many people from the region every season.
