Description
Technical field
The present invention relates to the method and apparatus of a kind of separating gold slice and solid fragment.
Background technology
Gold is the good conductor of electricity, and Never-rusty, and processing characteristics is very good.Computer, mobile phone etc. are pursued in the electric equipment products of small-sized microminiaturization, and gold is requisite material on the electronic circuit.For the needs of the utilization of resources and environmental protection, communication product factory introduces special-purpose device for disassembling one after another, picks out to contain gold dollar spare from loose mails such as the old computer that disintegrates, mobile phone.In recent years, eliminating sharply of electric equipment products such as old computer, mobile phone accelerated.Developed country all will reclaim a large amount of gold and silver every year from secondary resource.According to statistics, exploiting 1 ounce of gold needs 250 dollars～300 dollars, and reclaiming 1 ounce of gold only needs 100 dollars.If the old and useless battery of mobile phone the inside is reclaimed, save bit by bit 1 ton and just can therefrom extract 100 gram gold.And common gold containing ore (sand) 5 grams that can only extract per ton, many persons are no more than tens grams.We can say that old mobile phone is a kind of quite high-grade Gold Ore.According to statistics, developed country, 1981-1985, annual gold and silver, platinum, the palladium output that reclaims from secondary resource accounts for 30%, 40%, 10%, 54.7% of mineral products amount then respectively.This ratio is along with the rapid quickening of eliminating of electric equipment products in recent years also sharply increases.Simultaneously, because artificial exploitation, make that gold ore is petered out on the earth, therefore reclaiming gold from gold-containing scrap will be the important component part that gold is produced.Thereby this work has very important and profound significance.
Thereby how environmental protection in the scrap stock that produce from the gold-plated component of these electronic products and gold-plated component production process, efficient, economic recovery gold are the focus and the difficult point of research at present.
People adopt the whole bag of tricks to be dissolved in the gold-plated thin slice on the refuse material in the solution usually or make gold mud, and then by methods such as reduction, absorption and electrolysis gold are separated.Ordinary method has nitro-compound oxidation style, aqua regia dissolution method, molten method, thiocarbamide method and the electrolytic process etc. of soaking of nitric acid.These method shortcomings are many, as: cyanating solution severe toxicity, chloroazotic acid is seriously polluted, the rate of recovery is low, purity is low, complex process, cost is high and it is big etc. to invest.Therefore the investigator is devoted to explore the environmental protection and economy recovery method of gold-containing scrap.The modest and amiable Luo Kun of Lu of Metal Inst., Chinese Academy of Sciences is by extract gold from the expensive liquid of direct electrochemical cyaniding (patent 93115991.1).Zhongshan University once Chinese, Zhu Shiping, Lu Yun contacts activated carbon fiber with ADSORPTION OF GOLD with the gold-containing solution of various concentration, sorbing material and solution separating, obtains gold (patent 88108274.0) after calcination after contact for some time.Resin methods such as the Gong Chun of Changchun Gold Research Institute dragon, Chen Minyou, Du Shufen, Yuan Ling are handled gold mud purifying gold (patent 200610017035.1).University Of Qingdao crow good year moves back golden liquid with prussiate earlier and will give up the gold-plated complexing on transistor surface in liquid, to contain golden liquid diluting again and heat and be placed on the dc electrolysis groove, gold is deposited on the stainless steel cathode plate, and scrape then and get, clean with acid solution again, get gold (patent 95110534.5).Beijing precious metal smelting factory uses I
2-NaI-H
2The O system reclaims gold with reduced iron powder displacement or S-WAT reduction method again with the gold plate corrosion on the waste electronic device.The auri waste material (waste slurry, cotton balls, circuit element) that Kunming Institute of Precious Metals produces thick-film technique evaporates respectively, burns and be broken, concentrates roasting then, roasting hydrochloric acid for dreg eccysis soluble impurity, and chloroazotic acid leaches gold, platinum, palladium, uses Na
2SO
3The preferential precipitation gold.It is raw material that Kunming Institute of Precious Metals reclaims gold with spent catalyst, repeatedly leaches with hydrochloric acid and oxidizer containing chlorine, makes gold change solution over to, and zinc dust precipitation, hydrochloric acid add the oxidizer containing chlorine dissolving, oxalic acid reduce the proof gold powder.In recent years, Tsing-Hua University has synthesized diisooctyl thioether and diisooctyl sulfoxide, has studied the extraction ability of precious metal, has set up the technology that reclaims gold with diisooctyl thioether extracting gold from electron device.Abroad, the Louis Karstlo Enrique Miguez G of Spain Vigo has been invented a kind of method and apparatus (patent 98814359.3) that is used for separating the gold particles that is deposited on clay, earth and mud.In some gold mine enterprises, adopt flotation process to replace traditional concentration from placer, to reclaim gold.The method Lian Watede flotation machine that Denver company makes can be used for the recovery of gold dust.The flotation column that Russia national non-ferrous metal research institute makes, (pH=7～9) carry out flotation in neutrality or weak alkaline medium.These gold are " easily floating " gold and particulate gold in ore in sand form mainly, and granularity is very thin.In addition, also have flats and sheet macrobead (1mm) gold to be distributed in the crack of quartzy inclusion (forming in the placer handling process).
