Description
Technical Field
The utility model relates to the technical fields of mineral processing, metallurgy and chemical industry, in particular to a comprehensive recycling system for volatile smoke dust generated by chloridizing, reducing, roasting and volatilizing cyanide tailings.
Background
The full mud cyanidation method is one of the most widely used gold extraction methods for gold production enterprises at present. Since the 80 s of the last century in China, along with the increase of mineral resource exploration and the discovery of a large number of gold-containing mineral deposits, the gold extraction process technology of the full-mud cyanidation method is rapidly developed, and the full-mud cyanidation method becomes a production process which is most widely applied in the provincial gold production enterprises, and the principle flow is as follows: raw ore crushing, ore grinding, grading, thickening, cyaniding, carbon adsorption, gold-loaded carbon, analysis, electrolysis, purification and ingot forming. The process adopts sodium cyanide for cyanide reaction to produce a great amount of cyanide-containing tailing waste slag, and the cyanide-containing tailing waste slag is piled up for a long time, so that the environmental hazard is great. Therefore, cyanide-containing tailing waste residues are urgently needed to be treated, and potential hazards are eliminated.
The technology for treating the cyanide-containing tailing waste residue by an alkaline chloridizing method and an incineration method has the characteristics of simple process equipment, easy operation, intermittent treatment, continuous treatment, readily available raw materials, quick response, relatively small investment and the like, and becomes a technical method for treating the cyanide-containing tailing waste residue with practical application value at present.
The incineration method is to put the cyanide-containing tailing waste residue into an incinerator, and burn the cyanide-containing toxic substances into non-toxic products under certain high temperature conditions. During incineration, the cyanide-containing tailing waste residue, coal and clay (containing quicklime) are mixed and stirred at a ratio of 6:4:1, then are subjected to ball making by a ball making machine, are placed into a special incinerator (the furnace temperature is less than 850 ℃ and the micro negative pressure is operated), and the waste gas is discharged into a 30m high chimney by a draught fan after dust removal by a dust remover and then is discharged into the atmosphere. Wherein, the quicklime plays a role of sulfur fixation, the dust collector collects smoke dust and is used for making balls, the combustion ash slag is crushed and then used for making bricks, the removal rate of cyanide in the cyanide-containing tailing waste slag can reach more than 90% after incineration, and the removal effect is obvious.
The cyanide-containing tailings overcome the reaction activation energy at a certain temperature (600 ℃), the CN-energy of the cyanide-containing tailings is completely oxidized, and the oxidation mechanism is generally considered as follows:
the chloridizing roasting refers to a process of separating and enriching valuable metals and other components by converting certain components in materials into gas or condensed-phase chlorides under certain conditions under the action of a chloridizing agent. The chloridizing sintering process is mostly used for treating pyrite cinder, high titanium slag, nickel-poor ore, laterite ore, tin-poor ore, complex gold ore and bismuth-poor composite ore.
Chloridizing roasting is one of the most widely used chloridizing processes. In the case of direct chlorination, as mentioned earlier, it has been used in production to treat gold and silver ores as early as the eighteenth century. Since more than a century, direct chlorination has been studied for extended application in the treatment of many mineral raw materials containing heavy non-ferrous and noble metals, with the most successful comprehensive utilization of pyrite cinder. Heretofore, neither medium-temperature chloridizing roasting nor high-temperature chloridizing roasting has been successfully used for comprehensive utilization of pyrite cinder on an industrial scale. As for reductive chlorination, it is known that the use of the processes such as chlorination of titanium dioxide (the main component of rutile or high titanium slag) and chlorination of magnesium oxide (or magnesite) has been an important link in the production of metallic titanium and magnesium.
The chlorinating agents commonly used for chloridizing roasting are: cl2, HCl, naCl, caCl, etc. The main factors influencing the chloridizing roasting are temperature, chloridizing agent type and concentration, gas phase composition, gas flow speed, material granularity, void fraction, material mineral composition, chemical composition, catalysis and the like.
The waste gas generated in the process of chloridizing reduction roasting tailings mainly comes from a roasting process, a great amount of chlorine-containing flue gas and smoke dust are generated by adopting a reduction chloridizing roasting process, although hydrochloric acid and chloride salt are recovered through leaching absorption, the flue gas still contains a small amount of chlorine, standard emission can be realized after alkali absorption treatment generally, even standard non-standard conditions exist, the volatilized products mainly comprise ZnCl2, pbCl2, cuCl2, auCl, agCl and the like, the formed products are the mixture of corresponding salts of the metals, the metals are treated by the flue gas, and the metals are not recycled, so that the value of the smoke dust containing the chloride salt is not fully reflected.
