DescriptionThe sustainable use of mineral resources, including side streams, should be enhanced. To make
testing, piloting and exploiting of the critical element resources easier, GTK’s modular recovery
process services for hydrometallurgy and water treatment will be enhanced and validated. Service
enhancement will be achieved through updating the pilot plant, piloting at active mine site, and
piloting recovery services for environmental applications.
PartnersGTK is a well-known provider of mineralogical and traditional processing services for the mining
industry worldwide. GTK’s process mineralogy focus has made the research center a leader in
mineralogical analysis in the development of concentration methods. GTK’s pilot water treatment
plant has been under development since 2012. The modular plant is designed to run longer term
tests at mine sites utilizing different possible technological combinations, based on which larger scale
water treatment processes and facilities can be designed. Besides water treatment, the pilot plant has
been noted to be suitable also for metal recovery, with some technological updates. So far, the pilot
plant has been tested in water treatment and base metal recovery. The pilot plant is co-owned by
GTK, Savonia and the University of Eastern Finland. Currently it consists of mixing and filtering
technologies from SMEs like Wetend and Sofi Filtration. To complement GTK’s service capacity, a
concept of modular recovery process service package for hydrometallurgy and water treatment will be
created and the pilot plant up-scaled and validated for hydrometallurgical processes.

Organic adsorbents have been developed to be a significant eco-efficient and non-waste method of
recovering metals and anions from mine water streams. For example, a selective metal recovery
innovation (N10O) has been patented in the year 2009 (UEF) and brought for business in 2013
named as CH-Collector. The CH-Collector or N10O has been demonstrated to be able to remove
metals from liquid concentrate and to be re-usable for tens of times. Other potential adsorbent
materials investigated at the UEF include target modified biochars, which can be utilized alone or
together e.g. with CH-Collector to boost the recovery. These organic adsorbents have been tested in
laboratory scale and piloting has been done regarding water treatment and base metals recovery. In
this project, the adsorbents would be piloted in larger hydrometallurgical scale and in environmental
water treatment and recovery applications.

Savonia UAS

Savonia is one of Finland's biggest and most versatile universities of applied sciences. Our campuses are situated in Kuopio, Iisalmi and Varkaus. There are almost 6000 students and 600 employees at Savonia. In education we implement Open Innovation Space (OIS), where we combine learning, development, research, and teaching.
