Abstract
The invention discloses a pretreatment method for recovering gold and silver from waste water adsorbing gold-carried carbon for precious metal refining. The specific steps of the treatment method include that firstly, acid pickling is conducted for impurity removing, filtering is conducted after acid pickling, the filtered adsorbing gold-carried carbon is added to an incinerator to be incinerated after being drained off, and cinder obtained after incineration passes through an impurity screen; secondly, the screened cinder obtained in the first step is added to an impurity removing solution, meanwhile, catalyst A is added to the solution for impurity removing, and filtering and washing are conducted after impurity removing; thirdly, the filtered cinder which contains gold and silver and is obtained after impurity removing, filtering and washing is sent to a conventional refining subsequent treatment technology, and the filtered solution obtained in the second step is sent to the first step to be repeatedly used. According to the pretreatment method, the process is short; intermediate products are few; the carbon content of the cinder is low; the obtained cinder containing gold and silver can directly enter a gold and silver refining system; gold and silver are enriched to the maximum degree; operation is simple; compounding and smelting are not needed; the purpose of fast treating the gold-carried carbon to recover gold and silver is achieved, the treatment cost is lowered, and the accumulating amount of gold and silver of the process can be reduced.
Description
Technical field
The present invention relates to a kind of precious metal refinery waste water absorption gold loaded carbon reclaims in the pretreatment process, particularly gold smelting industry of gold and silver, and in a kind of gold refining waste water absorption gold loaded carbon, carbon-in-pulp process production, useless gold loaded carbon reclaims the pretreatment process of gold and silver.
Background technology
What the every annual meeting generation of gold smelting enterprise was a large amount of contains gold and silver waste water, wherein mainly comprises cyanide barren solution, gold mud presoak, gold refining waste electrolyte etc.More or less all the precious metals such as a certain amount of gold and silver are contained in these waste water, usual employing reducing process reclaims this part precious metal, but gold and silver thoroughly can not be reduced recovery by reducing process, needed to adopt activated carbon treatment before sending water treatment, the valuable metal ions such as absorption gold and silver.Water treatment absorption gac, after absorption for some time, can reach the dynamically saturated of absorption, and further can not adsorb gold and silver, needs process to reclaim gold and silver.This part gac is while absorption gold and silver, and other base-metal ion that content is high also can be adsorbed, and thus this part charcoal absorption impurity ion content is also higher.The amount of absorption gold loaded carbon is simultaneously less, is not suitable for adopting resolving electrodeposition method process, adopts additive method process comparatively suitable.
Simultaneously, the smelting enterprise producing gold is carried out for all sliming cyanidation-charcoal slurry absorbing process, the gold and silver precious metal leached in charcoal absorption ore pulp is adopted in cyanidation-leaching process, with the prolongation of charcoal absorption time, the adsorptive capacity of gold and silver increases gradually, just need manipulation of regeneration to reclaim gold and silver close to gold loaded carbon during absorption saturated capacity, this type of gold loaded carbon adopts parsing, electrodeposition process recovery gold and silver usually, and the activated process Posterior circle of the gac after parsing utilizes.Gac is along with the increase of cyclic regeneration number of times, and its activity and loading capacity reduce, gradually until inactivation, just can not adsorb after inactivation and resolve gold and silver completely, must discard, wherein gold and silver grade is higher, and this part useless gold loaded carbon also needs process to reclaim the valuable elements such as gold and silver.
Gold loaded carbon substantially all adopts traditional burning-melting technology process, first this method burns gold loaded carbon, then carry out prepare burden (borax, soda ash, SODIUMNITRATE etc.), compound carries out pyrometallurgical smelting at about 1200 DEG C, need to topple over smelting slag for several times in fusion process, obtain gold containing material after melting, generally according to the subsequent treatment process that the one-tenth component selections of gained gold containing material is suitable, reach the object reclaiming gold and silver.This method mainly exist process thoroughly in many, the smelting slag of (incineration slag carbon content is high), melting intermediate product gold and silver be mingled with the problems such as loss amount is large, processing cost is high, long processing period.
Chinese invention patent application publication number is CN102409176A, invention and created name is " technique of gold loaded carbon comprehensive treating process " process to gold loaded carbon, technical process is longer, intermediate product is many, and complex process, have employed pyrogenic process, wet method and cyanide process three kinds of techniques, due to lower carbon content can not be ensured after burning, the process of batching pyrometallurgical smelting must be carried out, be not suitable for carrying out fast processing to gold loaded carbon, the object of quick output gold and silver can not be realized.Chinese invention patent application publication number is CN103660568A, invention and created name is " method from containing gold recovering golden waste charcoal end " process to discarded gac end, roasting is carried out by adding loess, starch and soda ash batching, although can lower carbon content be ensured, but technical process is long, slag returns cyanidation gold-extracted silver, adopt charcoal absorption to resolve after cyaniding again and reclaim gold and silver, and not direct gold and silver in charcoal end to be reclaimed, and be only suitable for process waste charcoal end, be not suitable for processing active gold-carrying carbon.
Therefore, provide a kind of simple to operate, flow process is short, with low cost, process active gold-carrying carbon that can be easy, greatly reduces intermediate product, and the gold loaded carbon improving the rate of recovery of gold and silver reclaims the pretreatment process of gold and silver, has been a problem needing solution badly.
Summary of the invention
