AB  - This paper shows the result of examining lead, silver cadmium and copper extraction from lead-silver waste cake in the process of hydrometallurgical zinc production. Besides controlling of pH value, the lead-silver cake was leached at high temperature in calcium-chloride aqueous solution of different concentrations, different relations of cake quantities and leaching agent volume and different process duration time. It was noted that, at optimal chosen process parameters, the following can be extracted: approx. 95% of lead and silver, approx. 50% of copper and cadmium, and approx. 40% of zinc. The results show that chloride leaching can be a prospective method for increasing utilization of useful metals in the process of hydrometallurgical zinc production.

AB  - Many high purity salts are produced by dissolving pure metal in non-oxidizing mineral acids. If hydrogen overpotential on the given metal is high, then the rate of overall process is defined by reaction of hydrogen ion reduction. This study investigated the possibility of accelerated dissolving of metal zinc in sulphuric acid by introducing copper cathode on which evolving hydrogen is much easier than on zinc. It was found out that the acceleration of zinc dissolving is possible and, at constant surface of copper cathode depends on the quality of electrical contact between copper electrode and zinc.

AB  - Depending on the type of black sheet-iron pickling, with the acid sulphate (H2SO4) or sodium sulphate (Na2SO4), before electrolitic drifting of tin, at the production of tinned sheet-irons it was examined morphology of alloyed layer of FeSn2 using SEM microscope and diffraction of X-rays (X-RD). Supposed weight of tin is measured by EDAX analysis. Porosity of the surface was determined by ASTM specification and by potenciostic polarisation. Resistance on corrosion was measured through the ATC test, methods and AC impedance. Achieved results indicates on big importance of pickling type of white sheet-iron at his process of production.

AB  - Corrosion resistance of Cr - Ni (special steels) specimen is tested by electrochemical methods, numerical method of linear polarization and polarization resistance method in calcium-hypochlorite (Ca(OCl)2) solutions. With increasing of Ca(OCl)2 concentration, pH value of the solution increases, as well as active chlorine concentration and corrosion activity of the medium. According to the quantitative method of the corrosion resistance determination it can be concluded that the steels tested in 1 wt % Ca(OCl)2 solution are resistant, in 10 wt % solution constant, and in 50 wt % suspension less resistant. URANUS B6 showed the best corrosion resistance of all tested chromium - nickel steels in all tested corrosion mediums.

AB  - Phosphogypsum obtained by "wet procedure" for phosphoric acid production is actually calcium-sulphate dihydrate, CaSO 4 ·2H 2 O, which contains a high percent of impurities as well as radionuclides, originating from the basic raw material. Technology of phosphoric acid production by "wet process" intends for phosphogypsum to be a "sponge" that absorbs all impurities from phosphoric acid (except uranium) and to be left in deposits as an unnecessary burden. As an enormous amount of phosphogypsum results from phosphoric acid production (the ratio is 5:1), phosphogypsum deposits are a burden per se, from the view of environmental protection, because they occupy large areas and may contaminate the air, ground water, but also surface water that receive phosphogypsum in the form of dilute suspension. By the proposed procedure, phosphogypsum is transformed into hemihydrate, CaSO 4 ·1/2H 2 O. Im the process of removing radionuclides with barium-sulphate, 226 Ra isotope content decreases below the permitted concentration, but this process is directly dependent on the type of the phosphate utilized in phosphoric acid production.
