AB  - In this paper the ability of three natural zeolites from different localities (Vranjska banja-VB, Igroš-I and Baia Mare-BM deposits) to remove copper has been investigated. These three zeolites were subjected to the elementary analysis as well as XRDP and DTA/TG analysis due to complete characterization. Cation exchange capacity of VB, I and BM zeolites were 150.1, 169.2, and 176.5 meq/100g. The maximum adsorption capacity for the copper adsorption on VB, I and BM-zeolites were 7.75, 8.51, and 11.18 mg/g. Based on the obtained results the mathematical expression that describes correlation between the CEC and copper adsorption capacity has been developed. This linear dependance has been tested with the vast variety of experimental results. According to this expression it is possible to predict the copper adsorption capacity for different zeolites based only on their CEC value.
AB  - U radu su prikazani rezultati ispitivanja uklanjanja jona bakra primenom tri prirodna zeolita sa različitih lokaliteta (Vranjska banja-VB, Igroš-I i Baia Mare-BM). U cilju karakterizacije zeolita, izvršena su ispitivanja elementarnog sastava, kao i rentgenska (XRDP) i termijska analiza (DTA/TG). Kapaciteti katjonske izmene (CEC) ispitivanih zeolita VB, I i BM iznose 150,1, 169,2 i 176,5 meq/100g. Maksimalni adsorpcioni kapaciteti bakra na VB, I i BM zeolitima iznose 7,75, 8,51, i 11,18 mg/g. Na osnovu ostvarenih rezultata, dobijena je matematička zavisnost koja dobro opisuje vezu između vrednosti CEC i adsorpcionog kapaciteta za bakar. Ova lineralna zavisnost je testirana primenom različitih eksperimentalnih rezultata. Primenom ove zavisnosti moguće je da se predvidi vrednost adsorpcionog kapaciteta bakra na različitim zeolitima poznavanjem njegove CEC vrednosti. .

AB  - This paper presents the results of research on mechanical activation of raw talc in a high-energy speed rotary mechanoactivator. The results of research on effect of mechanically activated talc on the degree of recovery Fe 2O 3 by hydrometallurgical method are also presented. The process and mechanism of mechanical activation in this type of mechanoactivator were achieved by impact. The variable parameters of the mechanoactivator operation were: rate of rotor revolutions (n 0 = 10,000 and n 0 = 20,000 rpm), circle sieve mesh (80, 120, 200 and 500 μm) and the current intensity. The following parameters of the dry mechanical activation process were studied: mechanical activation time, rotor speed, mechanoactivator capacity and specific energy consumption. The mechanically activated powder was examined by application of differential thermal and thermogravimetric analyses, analysis of the degree of mechanical activation and the specific surface area as well. According to the obtained results, the highest rate of mechanical activation was obtained with a nominal mechanoactivator load. The degree of mechanical activation increases with increasing the rate of rotor revolution, circle sieve mesh size and with the increasing mechanoactivator load. It was shown that high-grade talc concentrate with low content of Fe 2O 3 can be obtained by physical-chemical process. A new approach for obtaining high-grade talc concentrate was achieved trough mechanically activated talc effect on the degree of recovery of Fe 2O 3 by hydrometallurgical process.
