Nowadays, business environment is faster than ever in the field of new technologies. The firms are forced to find new ways to compete and survive through innovations. To meet these demands, different tools and techniques are used in order to measure capability of firms to innovate. One of them is the Value Innovation Potential Assessment Tool, which helps to identify appropriate opportunities for firms to use it to assess their effectiveness of innovation work. The main goal of this paper was to investigate the Value Innovation Potential under transitional conditions in some firms in South-Eastern Serbia. The research was done using a questionnaire taken from literature, which was applied to one hundred employees in mentioned Serbian firms. The data were statistically analysed, explained and main conclusions were obtained. Proposed factor model of Value Innovation Potential was tested using confirmatory factor analysis (CFA) on investigated population.

Copper flotation waste, generated as a byproduct of pyrometallurgical copper production, contains a significant amount of Cu together with trace amounts of other toxic elements such as Fe, Sn, Sb, As, and Pb. It is usually disposed in uncovered tailing ponds in the vicinity of a copper smelter plant. Heavy metals released into the water and soil can cause a number of environmental problems. The amount of copper in copper flotation waste is high enough to be extracted economically using appropriate methods. In this study, the leaching characteristics of copper flotation waste from the Bor Copper Mine, Serbia, were investigated to assess the feasibility of copper extraction.
