#0183;#32;Cyanide leaching has become the dominant gold extraction technology since the 1970s replacing previously used less efficient and more toxic mercury. These gold mines discharge effluent containing toxic cyanides into natural water bodies posing the greatest threat to the quality of water intended for human use.

Some of alternative reagents in relation to cyanides will be tested during the research. In order to recover in an ecoefficient manner the gold contained in the solutions resulting from leaching tests, the research examines direct magnetoelectrowinning techniques for different conditions to determine parameters that could be translated to further prototype developments.
Major applications of this interdisciplinary technology include biomining concepts, mineral beneficiation, metals extraction sulfide ores, limestone, ocean nodules, as well as goldbearing ores are analyzed with respect to role of indigenous microbial habitats and direct cyanidefree goldbiodissolution and biodegradation of cyanides.
metal ores (lt;1% copper, lt;1g/ton gold, lt; % nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009). In consideration of ore types, a generalized diagram showing the applicable ore beneficiation technologies for oxide and sulphide ores versus ore grade is given in Figure 2.
