Sandioss (SDS) is chemistry for the process soak gold from gold stone used in gold processing plants. This product was developed as a cyanide alternative with strong gold dissolving ability and more economical chemical costs.
 
 
 
Sandioss can be used on many types of gold stones, including:
 
 
 
 
gold oxide stone
 
 
 
 
semi-oxide goldstone
 
 
 
 
gold sulfide rock
 
 
 
 
fine gold stone
 
 
 
 
cyanide tailings
 
 
 
 
amalgam tailings
 
 
 
 
gold processing residue
 
 
 
 
anode mud and electronic waste containing gold
 
 
 
 
 
This product is suitable for various gold processing methods commonly used in mines.
 
Suitable Processing Method
 
 
 
Sandioss can be used in various gold processing systems, including:
 
 
 
 
Heap leaching (leach heap) / Siraman 
 
 
 
 
Pool leaching / soaking pool
 
 
 
 
Carbon in pulp (CIP / CIL) / Cask
 
 
 
 
Agitation tank
 
 
 
 
 
The process of using Sandioss basically the same as the cyanide process, so that gold processing factories usually no need to change the main equipment.
 
Rich solutions and poor solutions in the process too reusable, just like in the cyanidation process.
 
 
 
Sandioss Advantages
 
✔ Cyanide alternative for gold soaking
✔ High solution strength to dissolve gold
✔ High gold recovery
✔ Chemical costs are lower than some alternatives
✔ Can be used on various types of gold stones
✔ Suitable for various gold processing methods
✔ Powder form so it is easy to store and transport
✔ The solution can be reused in the process

Parameter
 
   
Mark
 
  
 
  
 
   
pH of the solution
 
   
around 10.5 – 11.5
 
  
 
  
 
   
ideal pH
 
   
around 11.2
 
  
 
  
 
   
Best working temperature
 
   
above 10°C
 
  
 
  
 
   
Solution concentration
 
   
around 0.2‰ – 1.2‰
 
  
 
 
 
 
 
 
If the pH is too high for a long time (above 12), it can affect activated carbon adsorption.
If the pH is too low (below 10.5), the gold soaking process may be less effective.
 
 
 
General Dosage
 
The dosage depends on the type of gold stone and the processing conditions.
 
 
 
Examples for gold oxide stones:
 
1 – 2 kg Sandioss per ton of stone
 
(or about 1.0 – 2.0‰ of the weight of the stone)
 
 
 
Actual amounts may vary depending on:
 
 
 
 
gold content
 
 
 
 
types of stone
 
 
 
 
sulfur or arsenic content
 
 
 
 
pH conditions
 
 
 
 
 
It is recommended to do pre-processing test to determine the best dose.
 
 
 
How to Dissolve the Product
 
Sandioss is in powder form and easily soluble in water.
 
 
 
General usage method:
 
 
 
 
Fill the mixing tank with water
 
 
 
 
Add the required number of Sandioss
 
 
 
 
Stir until completely dissolved
 
 
 
 
Add the solution to the soak tank
 
 
 
 
 
Dissolution is usually faster if:
 
 
 
 
water flow
 
 
 
 
sufficient stirring is done
 
 
 
 
 
Gold Recovery Method
 
Dissolved gold can be extracted using methods commonly used in gold factories, such as:
 
 
 
 
activated carbon adsorption
 
 
 
 
zinc powder precipitation
 
 
 
 
zinc wire
 
 
 
 
 
Storage and Security
 
Sandioss included common chemicals with characteristics:
 
 
 
 
non-flammable
 
 
 
 
not easily explosive
 
 
 
 
has no radiation risk
 
 
 
 
 
Storage:
 
 
 
 
store in a dry place
 
 
 
 
keep away from moisture
 
 
 
 
keep away from acidic chemicals
 
 
 
 
avoid contact with food
 
 
 
 
 
Operation Notes
 
Some important things when using Sandioss:
 
 
 
 
the gold soaking process is usually slower in the early stages, but faster in the middle to late stages
 
 
 
 
guard The pH of the solution remains stable
 
 
 
 
do periodic measurement of solution concentration
 
 
 
 
The chemical dosage must be adjusted to the condition of the gold stone.
