## Application of radiotracers in investigation of the selected hydrometallurgical separation processes

### Dominik Owczarek

#### Abstract

In the modern world, there is a constantly growing need for metals, particularly so called scarce metals, for example rare-earth elements. For this reason there is a need to use poorer sources and recover them as efficiently as possible. In this case the traditional smelting method cannot be used and in the case of poor materials/waste, the hydrometallurgy method of obtaining elements is developed. In this paper the above method was presented and it’s application for recovery metals was discussed. Descriptions of selected processes used in hydrometallurgical metals obtaining were also contained. In addition the basics of radiotracers technique were described. The experimental part includes results of a study, whose objective was optimiza-tion of the process of copper solvent extraction using radiotracers technique. The studies related to flotation waste and were done using mixer-settler from SX-Kinetics inc. It is laboratory pilot plant designed for countercurrent, multistage extraction and stripping in processes of separation/recovery metals from aqueous/organic solutions. The first stage was examination of effective separation of copper from waste. The impact of parameters such as concentration of the extractant or pH of the original solution on the extraction process was examined. The studies were conducted using the same volume of organic phase and water phase in the periodic process. Then the process of extraction in continuous-flow apparatus using radiotracers technique was done. As an indicator was used isotope of Cu-64 and Tc-99m. The work was made at the Institute of Chemistry and Nuclear Technique in Warsaw in cooperation with the International Atomic Energy Agency (within the Coordinated Research Project "F22065") within the project "Development of radiometric and radiotracers techniques for the hydrometallurgical process of recovery of deficit metals", which is cofinanced by the Ministry of Science and Higher Education.
