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 solid 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.
Our work consists of extracting minerals: GOLD – DIAMONDS – COPPER – MALACHITES and others. Marcxell Minerals performs geological expertise of more than 700 products to extreme challenges to adapt the best solutions to our clients.
