July 1 2013, Minelco changed name to LKAB Minerals

The Minelco brand has, since its formation in 1989, become well-known in the world of minerals. Today we feel it is time to build one strong global brand together with our owner LKAB. We remain the same company and the same people - application and mineral processing experts, with a focus on sustainability and customer value creation. From now on you will find us online at www.lkabminerals.com.

Mineral fillers

Minerals are used extensively in many plastic and rubber applications. LKAB Minerals manufacture and supply a wide range of mineral products developed for this industry which impart a vareity of properties from flame retardancy to reinforcement.

Reinforcement and dimensional stability

We manufacture both muscovite and phlogopite mica products for the plastics industry. When used in plastics, LKAB Minerals' Mica, a functional filler, imparts many benefits. One advantage is the platy nature of Mica; the particles align in the same direction during moulding. This means that Mica significantly increases plastics stiffness and greatly reduces distortion. As Mica is inert it can be used in variety of polymer types and end use applications. Excellent mechanical properties can be achieved with mica addition levels as low as 10 to 20%.

Char promoting fire retardancy

UltraCarb is the brand name for our flame retardant mineral product range.  UltraCarb is produced from natural deposits containing two minerals; huntite and hydromagnesite. UltraCarb is a natural and inorganic mineral flame retardant and smoke suppressant. It is used in a wide range of polymers such as polyethylene, polypropylene and PVC. The high heat absoprtion of UltraCarb protects polymers from a rapid thermal degradation and the formation of combustible products.

High density

MagniF is the brand name for magnetite grades which are used as a filler in polymer and rubber applications. MagniF is used primarily for its high density however it is also thermally and electrically conductive, ferri-magnetic and heatable by microwaves. MagniF filled polymers are considered straightforward to compound and mould. MagniF is particularly suitable for sound and vibration dampening applications within the automotive industry.

Viscosity control

The cut grades dolomite (FordaDol) we manufacture have a very specific particle size distribution with low fines which can contribute to high viscosity. FordaDol is useful in applications where process viscosity is a factor such as PVC plastisols.  FordaDol can also be used in polypropylene applications to provide a cost effective final product.

Decorative effects

DekorFlake is the brand name for our decorative mica products; this range is available in a variety of particle sizes and four natural colours. DekorFlake is compatible with a variety of organic and inorganic matrices and systems. The flakes are resistant to UV, weather, chemical and thermal degradation. Typical uses of DekorFlake include sanitary ware, polymer based flooring, solid surfacing, consumer plastic parts and containers, toys and cosmetic packaging.

Whiteness and high density

In general plastic mouldings the final weight is increased using Barytes additionally a moulding can be produced that is solid in appearance and cost effective to the moulder. Barytes provides a polymer with a high level of chemical resistance, the whiteness of Barytes is particularly useful in plastic applications.


FireCarb is the brand name for our expandable graphite product range. FireCarb is used in PVC door seals and pipe collars in the passive fire protection industry. The expansion of the FireCarb filled seals when exposed to heat provides a barrier to flame and smoke thus inhibiting the spread of fire.

Cost reduction

MicroCarb is the brand name for our chalk product range. Chalk whiting is used as a general purpose filler in rubbers and plastics to reduce overall costs and to enhance the polymer’s properties. Coated grades of MicroCarb are particularly well suited to PVC applications as they reduce plasticizer demand, assist dispersion and act as a processing aid.

Flame retardancy and smoke suppression

FordaGard is the brand name for our range of ATH products. ATH is used in plastics primarily for its fire retardant action. FordaGard is a non-smoking, low toxicity, halogen free flame retardant mineral making it useful in a variety of applications. Typical FordaGard applications include glass reinforced plastic (GRP), encapsulation resins, cable bedding compounds, solid surfacing, carpet backing and foam.

Mineral fillers products

  1. UltraCarb
    • UltraCarb is a natural halogen free mineral fire retardant filler suitable for plastics and rubbers, produced from a deposit of two minerals - huntite and hydromagnesite. Each of these two minerals are flame retardants in their own right, the combination, however, results in a unique new product whose specific properties may be adjusted by selected mining and processing to fit a variety of applications.

  2. Phlogopite Mica
    • Phlogopite Mica is a hydrated silicate of potassium, aluminium and magnesium, which has a bronze gold colouration. LKAB Minerals extract Phlogopite Mica from their unique source in Finland and using extensive mineral processing knowledge produces a wide portfolio of grades to suit many applications.

  3. Muscovite Mica
    • Mica is a group of lamellar silicate minerals distinguished by their high aspect ratio and visual glimmer. Muscovite Mica, the most common type worldwide, is a hydrated silicate of potassium and aluminium, and is predominately white in colour.

  4. MagniF
    • LKAB Minerals develop and market Magnetite, a natural iron oxide with unique properties. MagniF is the brand for specially developed Magnetite grades to be used as a functional filler for polymers and rubbers. Mined and processed at our own group resources in the north of Sweden ensures a long-term, reliable source of consistent quality material.
