(Carbon in Pulp)
1. Gold floatation concentrate
2. Amalgamating ore tailing, gravitation separation tailings
3. Clayish oxide gold ore
As one of the gold ore dressing processes, Xinhai gold CIP (Carbon in Pulp) process
is extremely popular with various gold ore dressing plants because of its high
adsorption rate, high recovery rate and low investment costs. Compared with other
gold ore dressing processes, Xinhai CIP process not only eliminates the expensive
solid-liquid separation process, but also further optimizes each production link, so
that the efficiency is improved obviously. According to the statistical analysis of
projects, Xinhai CIP process can help customers save investment costs
by 30%-50% and reduce production costs by
Cyanide slurry is screened to remove coarse-grained material and wood dust
before the adsorption. And the activated carbon is polished to grind off
sharp corners and edges before entering the adsorption tank.
√ Prevent the impurities from adsorbing gold and activated carbon then
mixing into the rich carbon, and avoid the wood dust blocking the carbon
√ Prevent the activated carbon debris from entering the slurry, then
cause the loss of gold.
If you have any questions, please contact us by the following ways, and we will provide you with better help!
Add Xinhai coconut
activated charcoal into the high-efficient cyanide leaching tank, then the
activated carbon absorbs the gold from the cyanide pulp and becomes the gold
loaded carbon. After the adsorption, the activated carbon and slurry are
separated by carbon screen.
√ Compared with the almond shell activated carbon, the strong adsorbability
of Xinhai coconut activated charcoal greatly improves the adsorption amount
and recovery rate of gold in associated metals; meanwhile, its great wear
resistant property reduces the loss of gold loaded carbon powder.
√ Xinhai washing thickener
adopts continuous discharging, which reduces multiple cycles of hydrothermal
gold, extends the time of pulp concentration and increases the washing
Gold loaded carbon is changed into gold mud and lean carbon in Xinhai desorption electrolysis
√ Xinhai high-temperature and high-pressure (150 ℃, 0.5 Mpa) can desorb 99%
of the gold in just 2-6 hours;
√ The cyanide complex ions of gold and silver in pregnant solution has is
relatively high concentration, which can be transformed to high purity solid
gold by Xinhai desorption electrolysis system.
After the simple pickling and impurity removal process, the gold ingots can be
obtained directly by high frequency melting furnace.
√ Ensure that the gold mud fully mixes with agents in the acid pickling
agitation tank, which can remove the impurities from the gold mud or acid
soluble inorganics from the solution.
After the regeneration, the lean carbon can be reused by adding a proportion of
new activated carbon.
√ After the desorption electrolysis, Xinhai coconut activated charcoal should
be pickled with dilute sulfuric acid (nitric acid), which can remove the
accumulation materials (such as carbonate). Then, it is sent to regenerative
furnace to recover the adsorption activity. Finally, its iodine value can
restore to 95% at least.
The continuous development and innovation of Xinhai has won countless honors, which is a
witness of the continuous progress.
