The native gold containing high silver, extracted from gold bulk of few kilograms, was comprehensively researched. The studied through the optical microscope gold samples seem homogeneous and their fineness varies from 200 to 500 ppm. The fineness deviates from the mean value about ±20-30 ppm, however zonation is not observed. When the gold samples were dissolved in nitric acid, only silver was released into solution and gold remained in the insoluble remainder as the spongy-porous skeleton, consisting of pure gol...

Returnable and non-returnable losses rise during melting and casting of molten metal. Non – returnable losses arise by melting and metallurgical treatment of molten metal as a back wash of evaporation, chemical reactions between molten metal and refractory lining, molten metal and air and between molten metal and refining additions. Value of these losses depends on the kind of alloy, on used furnace and charge quality. Except non-returnable losses, the returnable losses creates by melting. They represent a differe...

Current management of phosphate-bearing resources (mainly rock phosphates, RPs), which in fact are finite non-renewable sources, is quite far from the principles of sustainability and may cause an escalating price increase mainly because of increases in RP-processing costs. One of the most studied approaches in solubilization of insoluble phosphates is the biological treatment of phosphate-bearing materials. In this work, we propose a microbial extraction of phosphate from insoluble inorganic natural sources as a ...

Industrial activities have the direct goal to help increasing the quality of life of the population. Beside positive direct and desired effects of industrial activities these have also negative, undesired and sometimes unthinkable effects on the environment and society. Especially mining based industrial activities have several unwanted impacts on environment, but not only on environment. With the goal of assuring the sustainable development of our human society it is therefore necessary to evaluate industrial pro...

This study was conducted to analyze concentrations of heavy metals in plants and soils of barley fields which were growing around of Konya city (Central Anatolia, Turkey). The samples of plants and soils were collected from different areas of two directions (North and South) and two distances (0 and 50 km) of the city. The samples of plants were analyzed for heavy metals (Pb, Zn, Cu, Cr, Ni) measured by ICP-OES.
