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
Technical field
The present invention relates to a kind of method for improving the rate of filtration, more particularly to a kind of to improve the desorbing electrolytic gold mud rate of filtration
Method.
Background technology
People began to that gold silver is reclaimed from gold-containing solution with activated carbon early in 1880.But as a kind of new work for carrying gold
Skill is until 20 century 70s are just developed rapidly and are reached perfection.From U.S. Homestake carbon pulp factory in 1973 go into operation with
Come, carbon-in-pulp process technique has worldwide become a kind of main gold extracting method for generally adopting at present.
Carbon-in-pulp process is the gold leached using activated carbon adsorption, and after desorbing electrolytic, the gold mud of generation is obtained again through refine
To ingot.When electrolysis, the conventional material of negative electrode has steel wool and NACF (charcoal felt).Carbon fibe has reinforcing electrodeposition
Process, improves cathode-current density, under identical electrolytic condition, with the deposition response rate and speed ratio steel wool of carbon fiber gold
When it is much higher；Because carbon fiber is inert electrode, redox reaction is participated in unlike steel wool, so electrodeposition gold mud out
Impurity content is few.Based on these advantages of carbon fiber, increasing manufacturing enterprise is used for carbon fiber in production.But pass through
The gold mud that carbon fiber electrodeposition is obtained, the problem for being difficult to filter is frequently run onto in subsequent wet refine, and filtration time is short then several
Hour, long then tens hours.The reason for gold mud filtration difficulty, except there is gold loaded carbon not wash clean clearly, carry a part of thin
It is outer that mud is produced into gold mud, and topmost reason is that the extremely fine carbon fiber mixed in gold mud is caused.Gold mud mistake
Filter difficulty causes refinery activities, and time-consuming, causes personnel, equipment fatigue, increased energy consumption, while also giving safeguarding work band
Carry out certain hidden danger.Therefore, study a kind of method to solve the problems, such as that desorbing electrolytic gold mud filtration hardly possible is very necessary.
The content of the invention
It is an object of the invention to provide a kind of method for improving the desorbing electrolytic gold mud rate of filtration, solves gold mud filtration
Difficult problem, shortens refining time, improves work efficiency.
The method of the present invention is：Gelatin and Polyethylene Glycol are added in desorbing electrolytic gold mud solution, is then sufficiently stirred for mixing
Close, after adding gelatin and Polyethylene Glycol to be thoroughly mixed, the rate of filtration of desorbing electrolytic gold mud solution is accelerated；Gold mud can be improved
Filter effect.
Described gelatin adds water and is configured to saturated solution.
The key technology of the present invention is being used in combination for gelatin and Polyethylene Glycol.
The step of the present invention is as follows：
First, the preparation of gelatin and Polyethylene Glycol：Gelatin is added water and is configured to saturated solution；
2nd, use：
Gelatin saturated solution and Polyethylene Glycol are added in the aqueous solution or acid treating solution of desorbing electrolytic gold mud, stirring is equal
Filter after even.The addition of gelatin and Polyethylene Glycol can be determined by experiment, and the gold mud consumption of different batches is different.
Beneficial effects of the present invention：
The rate of filtration of desorbing electrolytic gold mud is remarkably improved, shortens refinery activities' time, reduce energy consumption.
Specific embodiment
The method of the present invention is：Gelatin and Polyethylene Glycol are added in desorbing electrolytic gold mud solution, is then sufficiently stirred for mixing
Close, after adding gelatin and Polyethylene Glycol to be thoroughly mixed, the rate of filtration of desorbing electrolytic gold mud solution is accelerated；Gold mud can be improved
Filter effect.
Described gelatin adds water and is configured to saturated solution.
Experimentation has been carried out using the present invention to two kinds of gold mud.Test adopts 2XZ-4 type vacuum pumps, 2500ml sucking filtration
Bottle, Φ 150mm buchner funnels.
