In the industrial sector, MIMI Tech GmbH has had varied tasks like FMEA risk analysis of metallurgical and manufacturing processes, environmental assessment of materials, literature reviews and state of the art benchmark, process chain design and process window definition, thermochemical modelling of metallurgical reactions and metal stability, Life Cycle Analysis (LCA), and more.
MIMI Tech GmbH MIMI has extended its operations in both domains: public as well as industrial sector. We account with public funded projects financed by public German entities like BMBF as well as at the European level with the EIT RawMaterials and EU Horizon 2020.
In the private sector, MIMI Tech GmbH has been quite active in sectors like lead, copper, aluminum, precious metals production, as well as, recycling companies and metallurgical plant constructors, between many others. you can also check some of our references and picture our strong network in europe.
here some of our most important public projects and some exemplary industrial work.
Green Silver (BMBF)
INTUITION (EIT Raw materials)
The supply situation of raw materials for Germany shows that silver is classified as particularly critical. With 10 % of a global silver consumption, Germany has high demands while 100 % dependency on imports. Canada is a major trading partner due to its rich precious metal resources has got a long history and considerable expertise in the field of precious metal production and in terms of raw material supply of silver. In the recovery of silver the leaching with cyanides is state of the art. However, due to their high toxicity, cyanides have a significant risk to humans and the environment.
This project aims to reduce, with an innovative combination of some known and some newly developed processes, the need for thiosulfate significantly and thus in addition to the already existing environmental benefits. Additionally it should be more economic as the leaching process using cyanides. One approach is the use of activated water. This allows the use of thiosulfate at constant efficiency and less needs of chemicals. The second approach is to convert thiosulfate out of the mine sulfur residues under same conditions carried out already in the Yukon Inc. stabilization of arsenic sulphide residues. Ideally, the environmentally critical cyanidation can be replaced by the ecological thiosulfate leaching with the use of activated water and the thiosulfate generated in situ without the need for additional chemicals.
CoFBAT Cobalt Free Solutions for Batteries (EU)
LIBRES Li-Ion Battery Recycling (Norwegian)
Norway has the highest EV fraction of new car sales in the world. Also in absolute numbers, EV sales are large. Norway also has a competent metallurgical industry and an efficient battery collection scheme. This combination is a strong basis for development of a successful LIB recycling process.
The commercial project partners (Batteriretur, Hydro, Glencore Nikkelverk and Keliber OY) have separate interests along the lithium battery recycling value chain. Together with R&D partners with relevant strong points (Elkem Technology, MIMI Tech (DE), Agder University (UiA,MIL) and NTNU), we aim to develop and commercialize a new LIB recycling process that shall be suitable for the large future volumes and have a much higher material recovery rate than today's state-of-the-art.

MIMI Tech GmbH is participating in CoFBAT project: Advanced material solutions for safer and long-lasting high capacity cobalt free batteries for stationary storage applications.
CoFBAT project aims towards development of novel solutions for battery storage with a modular technology, suitable for different applications fulfilling the increasing need of decentralised energy production and supply for private households and industrial robotised devices. CoFBAT will strengthen the EU competitiveness in advanced materials and the related battery value chain by developing a cobalt free solutions and safe polymer electrolytes. CoFBAT gathers the whole value chain in battery production from materials to battery manufacturing, including electrochemical characterization and life cycle assessment.
CoFBAT gathers a consortium of 19 partners from 9 countries having received a funding from European Commission of 7.9 M EUR.
Duration: 2018 - 2022

Vacuum metallurgy course
Key asset of the EIT RawMaterial Network is the knowledge present in systems and people at different partners. The big challenge is to structure this data, to make it accessible and to combine it into information that creates value for the users. The value of information is related to the degree of help in decision making.
The Information CapTurng of Industrial Needs and Solutions (INTUITION) project wants to verify on a real live case , whether the data model developed during the PEPS project, can establish a backbone for the RM Knowlegde-base as part of the INFOCENTRE service, registering needs and solution in process steps within a metallurgic value chain. The use of data model will be based on real value chain in metallurgic industry and checked to which level of detail industry is willing to share this information and which level of detail is required to be relevant for the users of this data.

Review on modern lead applications
In the extractive metallurgy aggressive chemicals are often used, which can negatively impact the environment. The use of transformative technologies ultrasound, microwaves and plasma is a promising alternative. A promising approach for optimization is to increase the reactivity of the solvent solution using microwaves, ultra-sonic or plasma technology. This pre-treatment increases the leaching efficiency while retention time and chemical consumption can be reduced significantly. With this simple process, less profitable ores, mining residues or secondary residues can be reused as raw materials.

SUBLIME Solid state sUlfide Based LI-MEtal batteries (EU)
Grant agreement ID: 875028
External link: Website
SUBLIME (Solid state sUlfide Based LI-MEtal batteries) aims at a wide deployment of electric vehicles (EVs) by addressing important consumer needs such as lower prize, long distance traveling, fast charging. In addition, a significant increase of EV adoption through the development of a complete value chain (from requirements to testing, including recycling path and life cycle assessment) for new sulfide electrolyte based solid-state battery cells (Li metal as anode, Ni rich NMC material as cathode) with high capacity and high voltage stability. The battery will be inherently safe and will be able to operate at room temperature or lower. Over the course of the project, interfaces displaying a fast Li-ion transport will be designed that increase the stability of the component. Partners will develop intimate and (electro)-chemically stable interfaces with strong mechanical features. Furthermore, deformability of sulfide allows good interfacial contact.
SUBLIME comprises a consortium of 15 partners from 8 countries having received a funding from European Commission of 7.89 M EUR.
