Rate is seriously higher, the problem of increasing enterprise's production cost.
The technical solution adopted by the present invention is that：Include the following steps：
(1), using the ore handled by carbon slurry therapy extracting gold method, fineness corresponding with carbon slurry therapy extracting gold method and matter are prepared
The ore pulp of concentration is measured, -74 μm of ore fineness accounts for 70%~90%, mass concentration 30%~50%；
(2), activated carbon is subjected to dry screen with the sieve that sieve pore is respectively 3.35mm and 1.0mm, screens out bulky grain therein
Charcoal and particulate charcoal remain larger than 1.0mm and the activated carbon less than 3.35mm；
(3), the ore pulp for (1) preparing step (2) treated activated carbon with step is with water quality ratio in activated carbon and ore pulp
It is 1:3~1:5 ratio mixing, and in dischargeable capacity 0.05m3Stirred tank in mechanical agitation polishing pretreatment 1~3 hour,
Stirred tank specifications parameter：Groove body height 500mm, groove body diameter 450mm, four leaf blade impellers, impeller diameter 180mm, impeller are most
Big rotating speed 580r/min；
(4), step (3) after treatment, the sieve for being 1.0mm with sieve pore isolates activated carbon from ore pulp, and screens out
Particulate charcoal less than 1.0mm, remains larger than the activated carbon of 1.0mm；
(5), the activated carbon that step (4) obtains fully is washed with clear water, then filters moisture, is dried for standby.
The pretreatment of activated carbon is a vital link in gold industry production, passes through the reasonably side of pretreatment
Method polishes off the wedge angle, seamed edge and open texture of activated carbon, and charcoal wear rate, less can be reduced using pretreated activated carbon
The loss late of gold.
The method have the advantages that：Using the consistent ore pulp of ore fineness in being produced with carbon slurry therapy extracting gold method and mass concentration
As medium, mechanical agitation pretreatment is carried out to activated carbon in the stirred tank of certain specification parameter, has effectively polished off work
Wedge angle, seamed edge and the open texture of property charcoal, and in preprocessing process activated carbon loss late it is low.With activated carbon in stirred tank with
Water is that the churned mechanically preprocess method of medium progress is compared, the activity that Activated Carbon Pretreatment method disclosed by the invention is obtained
Carbon surface is smooth, and wear-resisting property is good, and the wear rate of charcoal is lower when being used in gold extraction by CIP process.
