Marcxell Minerals is the African leader in refractories. We have the largest number of sites in Africa and the most innovative and reliable products and services. We also offer the strongest security of supply and quality, thanks to our exceptional vertical integration – from mining to the production of complete service solutions.

Our Services

For us, it’s about using our advantages to accelerate innovation in our sector and offer the best to our customers. So we don’t take our market leadership for granted. We want to remain number one in Zambia and drive positive change in our industry and the sectors that depend on us. As a mining company, we use our resources, our presence in Africa, and our expertise to produce high-quality gold and diamonds. Marcxell Minerals constantly applies the latest technology and environmentally friendly equipment in our production to ensure the highest level of safety for our staff and the environment.

Refractory products are used in all high temperature industrial processes worldwide. Without them, the steel, cement, lime, non-ferrous metal, glass, energy, environmental and chemical industries could not exist.

Refractories defy the harshest conditions to remain strong and stable at temperatures of 1200°C and above. To safely contain materials when burned, sandblasted, fired, melted and shaped. And to protect equipment such as furnaces and ovens from thermal, mechanical and chemical stress.

Marcxell Minerals

Our work consists in extracting minerals: GOLD – DIAMONDS – COPPER – MALACHITES and others. To these extreme challenges, to adapt the best solutions to our customers, we establish a geological expertise of more than 700 products. The basic materials we use for export are:
The andradite: Demantoid, Topazolite, Allochroite, Melanite187 / Chrysocolla: Chrysocolla quartz / Silicified chrysocolla145 / Demantoid: (Andradite variety) 32 / Treated diamond: (HPHT, annealed / heating, irradiation) 418 / Diamond / Dioptase / Indigolite / Indicolite (blue tourmaline) 38 / Leucite / Magnesia 310 / Malachite 92 / Samarskite-(Y) 354 / Wulfenite1 – remarkable materials which themselves require skillful handling: the melting point of fused magnesia is above 2800°C.



We establish a lasting relationship with our customers. Signature of the contract; establishment of a payment guarantee by the buyer’s bank; agreement on the price including administrative costs and transport of the goods. Payment after testing or refining within 24 hours by bank transfer. Our conditions of sale are binding and immutable.

Dear associates and friends, you have told me that you like the direction Marcxell Group is taking and I thank you for that. In my capacity as CEO, President and Founder of the Group, I will therefore, for this mandate, assume the leadership of our entrepreneurial adventures on the road to success, confirming the steps already taken; our national and international deployment, which will be accompanied by the distribution of our products and services in a range of markets made infinite by the development of e-commerce, which I am making my hobbyhorse at the head of our Group.
