    Yanqul – Block 10 Rakka & Bishara Tailings Project Gold was successfully mined in Rakka and Bishara between 1994 and 2009, when environmental concerns over the contaminating and harmful nature of using cyanide to leach gold from the ore, which was also affecting nearby farms and villages, led to the closure of the mines and the Rakka gold processing plantThe processing technology uses onestage grinding, preferential flotation process The gold and copper concentrate product can be recovered once In general, the gold recovery method of gold tailings is mainly the allslime cyanidation CIPGold Tailings Reprocessing Technology xinhaiepc[Process Introduction] There are mainly several methods of gold tailings reprocessing: 1 The iron recovery from gold tailings can adopts common processing technology such as gravity separation, magnetic separation, flotation, roasting magnetic separation andgold tailings processing equipment, gold tailings recovery
