INTMET Questionnaire

The project

INTMET is a European funded project titled. “Integrated innovative metallurgical system to benefit efficiently polymetallic, complex and low-grade ores and concentrates” ( The INTMET approach represents a unique technological breakthrough to overcome the limitations related to difficult low grade and complex ores to achieve high efficient recovery of valuable metals (Cu, Zn, Pb, Ag) and CRM (Co, In, Sb). Main objective of INTMET is applying on-site mine-to-metal hydroprocessing of the produced concentrates enhancing substantially raw materials efficiency thanks to increase Cu+Zn+Pb recovery over 60% vs. existing selective flotation. Three innovative hydrometallurgical processes (atmospheric, pressure and bioleaching), and novel more effective metals extraction techniques (e.g. Cu/Zn-SX-EW, chloride media, MSA, etc.) will be developed and tested at relevant environment aiming to maximise metal recovery yield and minimising energy consumption and environmental footprint. Additionally, secondary materials like tailings and metallurgical wastes will be tested as well for metals recovery and sulphur valorisation. The technical, environmental and economic feasibility of the entire approaches will be evaluated to ensure a real business solution of the integrated INTMET process.
INTMET will be economically viable thanks to diversification of products (Cu, Zn, Pb), high-profitable solution (producing commodities not concentrates), with lower operation and environmental costs (on-site hydroprocessing will avoid transport to smelters) and allowing mine-life extension developing a new business-model concept based on high efficient recovery of complex ores that will ensure mining industry competitiveness and employment.


With the following questionnaire, INTMET would like to invite you to take part in the further course of process development and its commercial application. It is a recommendation of the European Commission that funded research projects should look for commercialisation of their results. Therefore, we are forwarding a couple of questions to obtain an overview of the potential market for our process. The objective of the questionnaire is to collect information as detailed as possible about the processing of low-grade and/or complex ores in order to adapt the parameters of the INTMET process and, subsequently, identify potential application cases for it.
The questions mainly relate to your operational environment and parameters of the input and output of the processes you are using. To identify the individual case in the further assessment process, few questions concerning your organisation are included as well.
We would very much appreciate your contribution to our work. In any case of question, please don’t hesitate to contact us.

We thank you very much in advance for your contribution.
