  • Heap leaching of copper from the ores of Volkovskoe

    Heap leaching of oxidized complex and waste copper ores of the Volkovskoe deposit is considered. Based on the results of an investigation the preliminary granulation of milled ore with sulfuric acid (25–75 kg/t ore) is recommended. Introduction of this procedure leads to a decrease in the leaching time by 15–30 and allows one to obtain solutions more concentrated by copper.

    A process is provided for heap leaching ore to recover nickel. The process is particularly effective for ores that have a tangible clay component (i.e. greater than about 10 by weight). The process includes sizing the ore (where necessary) forming pellets by contacting ore with a lixiviant and agglomerating. The pellets are formed into a heap and leached with sulfuric acid to extract the
