Technical Field
The utility model relates to a processing field of gold leaching barren liquor especially relates to a device that removes zinc iron in gold ore gold leaching barren liquor.
Background
The cyanidation method is a method of using a mixed solution composed of cyanide and the like as a solvent for leaching gold, and currently, a method of using a NaCN aqueous solution to leach gold in gold-containing ores and then extracting the gold from a gold-containing leaching solution is commonly used. The cyanidation method for extracting gold mainly includes cyanidation leaching, in the presence of oxygen or oxidant in cyanide solution with certain concentration, gold in gold-bearing ore reacts with cyanide to produce complex of gold and dissolves in the solution.
Since gold ores generally contain other metal elements, the cyanide tail solution often contains metal ions such as Zn2+, Fe2+, Pb2+, Cu2+, and the like, in addition to cyanides. For the recovery of metal ions, the traditional recovery mode cannot better separate and recover zinc and iron.

The utility model aims at providing a remove device and method of zinc-iron in gold ore gold leaching barren liquor can deposit the gold leaching barren liquor that contains zinc-iron ion and filter and get rid of zinc-iron plasma, realizes the high-efficient sediment of zinc-iron ion, and separates. After separation, the supernatant can be continuously returned to the gold leaching system for use, so that better recycling is realized.
In order to solve the problems, the utility model discloses a device for removing zinc and iron in gold leaching barren solution of gold ores, which comprises a tube mixer for preliminary mixing raw materials, a buffer tank, a reaction kettle for chemical reaction, a thickener and a filter press for removing zinc and iron; the tube mixer is connected with the buffering feed inlet of the buffer tank, the buffering discharge port of the buffer tank is connected with the reaction feed inlet of the reaction kettle, the reaction discharge port is used for feeding the thickener, the upper layer of the thickener is provided with a clear water outlet, the bottom end of the thickener is provided with a precipitation discharge port, and the precipitation discharge port is connected with the filter press zinc iron mud.
Further, a buffer tank is arranged between the thickener and the filter press and used for temporarily storing zinc-iron mud sediment, and a pressure filter pump is arranged in the buffer tank and used for supplying materials to the filter press.
Further, the filter-pressing pump is provided with two pumps, wherein one pump is a working pump, and the other pump is a standby pump.
Further, an upper layer of paddle and a lower layer of paddle are arranged on the stirring shafts in the buffer tank, the reaction kettle and the buffer tank.
The beneficial effects of the utility model reside in that:
through the utility model discloses a device that removes zinc, iron in gold ore gold leaching barren solution can carry out effectual sediment and separation to the zinc iron ion in the gold ore gold leaching barren solution, and this reaction generates the cyanide coprecipitation of zinc and iron, and addition polyacrylamide flocculation, through the pressure filter solid-liquid separation after, the supernatant adds the alkaline back of sodium hydroxide and returns the gold leaching system and recycle.
