Services - from material testing to plant design

We offer a wide variety of services related to the processing of manifold raw materials - always involving highly qualified experts for the specific duties when required.


Our network consists of mining experts, metallurgical experts, electrical engineers, civil engineers, material scientists and many more to serve you exactly to your needs...

Processing tests

We plan, coordinate, execute  and evaluate sampling and processing tests in laboratory or pilot scale, that are conducted by ourselves or in cooperation with well equipped and highly qualified facilities (at suppliers, universities and other testing facilities) - whatever suits best to the task.

Process development

We design process flow sheets for the preparation of all types of raw materials - taking into consideration the application of state-of-the-art processes as well as the development of innovative processes for a more efficient material treatment.


Design work is usually based on the results of processing tests and includes mass and water balances, equipment sizing as well as capex and opex.

Plant concepts and budgeting

According to the process we also provide plant concepts with scaled GA drawings, cross sections and/or 3D-Models, including equipment lists for core equipment, material handling and transport, auxiliary devices, steel construction and electrical installations for the calculation of the according budgets.



Apart from or in addition to the above mentioned we offer the following techno-economic services:

  • Project development
  • Expert opinions
  • Feasibility studies
  • Technological studies
  • Process comparisons
  • Process optimization


Though CALA's focus is clearly on mineral processing, together with partnered companies we can  extend our scope of consulting to the adjacent fields of

  • Geology and Mineralogy
  • Mining
  • Metallurgy
  • Recycling
  • ...

Lecturing and training

We are well experienced in lecturing topics in between "fundamental processing for beginners" to "special processing issues".
