CALA Mineral Processing - Consulting and Engineering


From material testing to the process, from the process to plant design... 





An overview of raw materials and processes we already dealt with in the past.




Slag Processing

Recover metal from slags – and find precious applications for the by-products



Dry processing

Save water and energy, have dry products, each time those issues are important



CALA - Short company history

Our associates look back on a long term professional experience in many fields of materials engineering covering a wide range of minerals such as ores and coal, industrial minerals, construction materials (sand, gravel, crushed rock, other aggregates) and the recycling of secondary raw materials.


Since CALA's establishment in 2006, we serve as your independent consulting partner for project and process development, project management and engineering services, especially if you are seeking creative solutions which are not „off-the-shelf".


We serve and advise on practically all traditional types of mineral beneficiation processes and raw materials, as for example iron and precious metal ores, industrial minerals, coal and construction materials.


A great portion of our activities is concerned with some modern and innovative fields of processing. Hence, we have developed special expertise in the processing and valorization of metallurgical slags and bottom ashes as well as in the development of alternative dry processes to save water and energy.


It is our pleasure to get into a discussion on your project - just contact us!
