Abstract

The invention discloses a method increasing the rate of filtration of desorbed and electrolyzed gold mud. According to the method, gelatin and polyethyleneglycol are added into a desorbed and electrolyzed gold mud solution and then are fully stirred and mixed. After the gelatin and the polyethyleneglycol are added and fully stirred and mixed, the rate of filtration of the desorbed and electrolyzed gold mud solution is increased. Water is added into the gelatin to prepare a saturated solution. The method can remarkably increase the rate of filtration of desorbed and electrolyzed gold mud, shorten the refining working time and reduce energy consumption.

Description

A kind of method improving desorbing electrolytic gold mud filtration velocity
Technical field
The present invention relates to a kind of method improving filtration velocity, particularly a kind of method improving desorbing electrolytic gold mud filtration velocity.
Background technology
People just started as far back as 1880 from gold-containing solution, to reclaim gold and silver with gac.But as a kind of novel process of gold of carrying until 20 century 70s are just developed rapidly and reach perfection.Since U.S.'s Homestake carbon pulp factory in 1973 is gone into operation, carbon-in-pulp process technique has worldwide become the main gold extracting method of the one generally adopted at present.
Carbon-in-pulp process is the gold utilizing charcoal absorption to leach, and after desorbing electrolytic, the gold mud of generation obtains ingot through refining again.When electrolysis, the material that negative electrode is conventional has steel wool and activated carbon fiber (charcoal felt).Carbon fibe has strengthening electrolytic deposition process, improves cathode current density, under identical electrolytic condition, much higher during the deposition rate of recovery and speed ratio steel wool with carbon fiber gold; Because carbon fiber is noble electrode, unlike steel wool, participate in redox reaction, so electrodeposition gold mud foreign matter content is out few.Based on these advantages of carbon fiber, increasing manufacturing enterprise by carbon fiber for the production of in.But be through carbon fiber electrically and amass the gold mud obtained, usually run into the problem being difficult to filter when subsequent wet refining, filtration time is short then several hours, long then tens hours.The reason of gold mud filtration difficulty, except there being gold loaded carbon not wash clean clearly, carry in the thin mud to gold mud of a part outside producing, topmost reason is that the extremely fine carbon fiber mixed in gold mud causes.Gold mud filtration difficulty causes refinery activities length consuming time, causes personnel, equipment fatigue, adds energy consumption, also bring certain hidden danger to safeguarding work simultaneously.Therefore, study a kind of method to solve desorbing electrolytic gold mud to filter difficult problem be very necessary.
Summary of the invention
The object of the present invention is to provide a kind of method improving desorbing electrolytic gold mud filtration velocity, solve the problem of gold mud filtration difficulty, shorten refining time, improve working efficiency.
The method of the present invention is: in desorbing electrolytic gold mud solution, add gelatin and polyoxyethylene glycol, be then fully uniformly mixed, and add after gelatin and polyoxyethylene glycol be fully uniformly mixed, the filtration velocity of desorbing electrolytic gold mud solution is accelerated; The filter effect of gold mud can be improved.
Described gelatin adds water and is mixed with saturated solution.
Gordian technique of the present invention is the conbined usage of gelatin and polyoxyethylene glycol.
Step of the present invention is as follows:
One, the preparation of gelatin and polyoxyethylene glycol: gelatin is added water and is mixed with saturated solution;
Two, use:
In the aqueous solution or acid treating solution of desorbing electrolytic gold mud, add gelatin saturated solution and polyoxyethylene glycol, filter after stirring.The add-on of gelatin and polyoxyethylene glycol is determined by experiment, and the gold mud consumption of different batches is different.
Beneficial effect of the present invention:
The filtration velocity of desorbing electrolytic gold mud can be significantly improved, shorten the refinery activities time, reduce energy consumption.
Embodiment
The method of the present invention is: in desorbing electrolytic gold mud solution, add gelatin and polyoxyethylene glycol, be then fully uniformly mixed, and add after gelatin and polyoxyethylene glycol be fully uniformly mixed, the filtration velocity of desorbing electrolytic gold mud solution is accelerated; The filter effect of gold mud can be improved.
Described gelatin adds water and is mixed with saturated solution.
Two kinds of gold mud are adopted and invention has been experimental study.Test adopts 2XZ-4 type vacuum pump, 2500ml filter flask, Φ 150mm Büchner funnel.
