Abstract
The invention discloses an electrolyte for recycling silver from smelting slag. The electrolyte comprises the following components: 30-50 g/L of silver nitrate, 80-100 g/L of 5,5-dimethyl hydantoin, 40-60 g/L of succinimide, 25-45 g/L of EDTA (Ethylenediamine Tetraacetic Acid), 60-80 g/L of niacin, 20-50 g/L of potassium pyrophosphate, 40-60 g/L of potassium citrate, 20-30 g/L of 2-hydroxypyridine, 50-80 g/L of sodium thiosulfate, 15-25 g/L of fatty alcohol-polyoxyethylene ether, 10-20 g/L of polyethylene glycol, 2-4 g/L of sodium selenite, 10-15 g/L of 2-aminothiazole, 5-10 g/L of diethyl thiourea, and the balance of de-ionized water. Compared with traditional electrolyte, the electrolyte for recycling the silver from the smelting slag, disclosed by the invention, has a relatively simple requirement on electrolysis condition, can separate silver from the smelting slag, has high production efficiency and low environmental pollution, reduces refining cost and has a silver recovery rate of more than 99.5%.
Description
Technical field
The present invention relates to a kind of electrolytic solution, be specifically related to the electrolytic solution that a kind of smelted furnace cinder reclaims silver.
Background technology
Silver, a kind of silvery white, can break, plastic and the precious metal of reflecting power arranged, as decorative coating, widely apply at the artworks such as tableware, jewellery and artwork, because its good specific conductivity and solderability also are widely used in the industry such as electrical equipment, electronics, communication equipment and instrument manufacturing.At present, the electrolytic solution that smelted furnace cinder reclaims silver nearly all contains prussiate, and prussiate has extremely strong toxicity, and environment is caused severe contamination, and the harm people comes healthy.Along with the day by day enhancing of International Environmental Protection consciousness, be badly in need of a kind of novel environment friendly cyanide-free electrolyte of exploitation.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of smelted furnace cinder that does not contain prussiate to reclaim the electrolytic solution of silver.
Technical scheme of the present invention is as follows:
A kind of smelted furnace cinder reclaims the electrolytic solution of silver, it is characterized in that, comprise following component: Silver Nitrate 30-50 g/L, 5,5-T10 80-100mg/L, succimide 40-60mg/L, ethylenediamine tetraacetic acid (EDTA) 25-45g/L, nicotinic acid 60-80g/L, potassium pyrophosphate 30-50mg/L, Tripotassium Citrate 40-60mg/L, 2 hydroxy pyrimidine 20-30mg/L, Sulfothiorine 50-80mg/L, fatty alcohol-polyoxyethylene ether 15-25mg/L, polyoxyethylene glycol 10-20g/L, Sodium Selenite 2-4mg/L, thiazolamine 10-15mg/L, diethyl thiourea 5-10mg/L, all the other are deionized water.
Described smelted furnace cinder reclaims the electrolytic solution of silver, it is characterized in that described electrolytic solution electrolytic condition is: electrolysis temperature 70-90 ℃, and current density 200-500A/m
2, bath voltage is 2-4V.
During use, with the smelted furnace cinder 40-50 order powder of pulverizing, be laid on bottom of electrolytic tank, form slurry with the electrolytic solution mix and blend, be heated to 70-90 ℃, be incubated 1 hour, the beginning electrolysis is in the electrolytic process, silver ions in the slag, migrate to negative electrode, in cathodic deposition, thereby the silver in the copper mine is separated.The silver separation efficiency is high, and 95% can separate from slag with silver in the copper mine, is deposited on negative electrode.
The present invention does not contain prussiate by improving electrolyte prescription, and electrolytic solution is stable and toxicity is low, eliminated in the electrolytic process prussiate to the harm of human body and environment, the passivation of electrolytic process Anodic is well suppressed, and anode dissolution is normal, but the electrolytic solution long-time continuous is used.The present invention compares with traditional electrolytic solution, to electrolytic condition require fairly simplely, can at short notice the silver in the smelted furnace cinder be separated, production efficiency is high, environmental pollution is little, the rate of recovery of silver is greater than 95%.
