树脂工艺的十大优点
（与炭浆工艺比较）
阿希金矿在选择提金工艺过程中，进行了炭浆法和树脂法提金工艺的设计方案，比较后，选择了树
脂法提金工艺，阿希金矿消化实施的实践表明，树脂提金法与炭浆法比较，在许多方面优于炭浆法：
（1）由于树脂表面圆滑，机械强度高，磨损小，载金树脂损失小：另外树脂提金的选择吸附能力
强，金的选冶回收率比炭浆法高3.36%。
（2）由于粗粒金经重选单独回收，流程的矿浆细度-0.074mm95%降至-0.074mm90%，从而提高磨
矿系统处理能力10%左右。
（3）树脂法浸出！吸附矿浆浓度比炭浆浸出工艺提高5%-7%。
（4）因粗粒金单独强化回收，在树脂法浸出吸附过程中粗粒金减少，树脂法浸出时间比炭浸出工
艺缩短为16h，减少浸出吸附时间33%。
（5）炭浸工艺设计氰化钠消耗量为1.1kg/t,而树脂工艺设计氰化钠消耗量仅为0.795kg/t,树脂
法比炭浸工艺减少氰化钠用量28%。
（6）树脂消耗量每处理一吨矿石仅用25g/t，是活性炭消耗量的1/4，即降低单耗75%。
（7）树脂吸附选择性强，解吸电解后的金泥品位高，金泥含金60%，含银25%，是炭吸附电解金泥
品位的3倍，同时含贱金属很少，大大简化了冶炼工艺，冶炼回收率高达99.8%，合质金品位99.9%。
（8）树脂和活性炭相比，再生简单，不需在高温过程中进行，在生时不发生吸附剂的破损，也不
增加金银的损失。
（9）炭浆工艺比树脂工艺生产成本高，炭浆法工艺消耗活性炭100g/t,消耗氰化钠1100g/t,而树
脂法工艺消耗树脂仅25g/t,消耗氰化钠795g/t，仅主要材料消耗，使炭浆工艺生产成本比树脂工艺高
50元/两左右。
（10）炭浆法工艺设计总回收率89%，树脂法工艺设计选冶总回收率92.36%，树脂法工艺净增回收
率3.36%，每年可为国家多产黄金1540两树脂法工艺因成本下降，每年节省资金约146万元，提高回收
率，增加产量，净增收入462万元，每年增加效益共计608万元。
Instruction book for D301G ion
exchange resin
With over 30 years development and with the vigorously
help of Nankai University
of Tianjin,Hebei langfang New Age duilding materialxco
Ltd.has become an ion
exchange resin producing corporation with a certain scale
and with the integration
of scientific research and production.Now we produce over
50 types of resin.
D301G is a kind of macropore polystyrene ion exchange
resin.it is used exclus-
ively in gold extraction from alkali cyaniding mineral
immersion liquid.Owing to
the peculiar skeleton structure of polymer,this resin
has excellent physical and
mechanical properties and extremely high wear resistant
property.It has also a high
gold exchange speed and high adsorptive capacity.It can
separate gold and other
metal ion well.The elution and reproduce is easy.So it
is reslly an ideal material
for gold extraction in wet-process metallurgy.

Ten Advantages of Resin
Technique
(Compared with carbon-in-pulp
technique)
Gold extraction with carbon-in-pulp method and resin
method are compared as
optional gold extracion technique for Axi Gold Mine.After
compare,gold extraction
with resin method is adopted,which shows the following
advantages compared with the
carbon-in-pulp method on digestion and implementation
of Axi Gold Mine；
(1)Because of smoothness of resin surface,high mechanical
strength and small
abrasion wear,the loss of gold carrying resin is small.In
addition,because of the
high selective adsorption capacity of resin on gold extraction,the
recovery ratio
of gold selection and refining is 3.36% higher than carbon-in-pulp
method.
(2)Owning to the independent recovery of reselected
coarse gold,the fineness
-0.074mm 95% of ore slurry in flow chart is lowered to
-0.074mm 90%,which improve
about 10% of processing capacity of grinding system.
(3)Resin method improves the concentration of leaching
absorption ore slurry at
5%-7% compared with carbon-in-pulp method.
(4)Because the coarse gold is independently recovered,the
coarse gold in
leaching adsorption process in resin method is reduced,which
saves 16hours leaching
time compared with carbon-in-pulp technique,namely 33%
of leaching adsorption time.
(5)The consumption of sodium cyanide in carbon-in-pulp
technique is 1.1kg/t,and
for resin technique,it is 0.795kg/t,saving 28% of sodium
cyanide consumption.
(6)The consumption of resin for treatment of a ton of
mineral is 25g/t,which is
1/4 of that of active carbon,namely saves 75% of unit
consumption.
(7)Resin has high adsorption selectivity,The desorpted
and electrolyzed gold mud
has a high quality,containing 60% gold and 25% silver,which
is 3 times of carbo-
absorption electrolyzed gold mud.Meanwhile,there are few
metal-sheets,which
simplify smeltering technique greatly.The smeltering recovery
ratio is as high as
99.8% and the quality of smelted gold is 99.9%.
(8)The reproduce of resin is simple compared with active
carbon,need no
pyroprocess and there is no wastage of adsorbent during
reproduce and causing no
loss of gold and silver.
(9)The production costs of carbon-in-pulp technique
is higher than resin
technique.Carbon-in-pulp technique consumes 100g/t active
carbon and 1100g/t sodium
cyanide,while resin technique consumes only 25g/t resin
and 795g/t sodium
cyanide,saving about 50yuan/tael compared with carbon-in-pulp
technique.
(10)The overall recovery of carbon-in-pulp method is
89% while it is 92.36% for
resin method,with 3.36% net growth of overall recovery,which
brings 1540tael of
gold for our nation.Resin method saves 1.46million yuan/yesr
because of the
descending of cost,and increases Income of 4.62 million
Yuan/year because of
improving of recovery ratio and rising of output.The benefit
increased by resin
method amounts to 6.08million Yuan/year.
