Stop Relying on Cyanide
Learn How to Leach Gold Without Cyanide
Using Sandioss
Products + Operator Training for Real Mining Operations
Most companies only sell chemicals.
We teach your team how to run the process.
Promining provides Sandioss and sends experienced operators directly to your mine site to train your team.
The goal is simple:
helping mining operations transition away from cyanide in a practical and safe way.
All this at a cost roughly equivalent to the price of a drum of cyanide.
✔ Sandioss Supply
✔ On-site operator training at the mine
✔ Real operational knowledge

Calculate the Cost Savings of Sandioss vs Cyanide
Cyanide prices continue to rise and are often volatile. Many gold processing operations are now seeking safer and more cost-effective alternatives to cyanide.
Use the simple calculator below to calculate how much you could save by replacing cyanide with Sandioss for gold leaching.
Enter the number of cyanide drums you typically use and the price per drum, then instantly see estimated cyanide costs, Sandioss costs, and potential savings for your mining operation.
Calculate now and see how much savings you can get by switching from cyanide to Sandioss.
The Real Problem With Cyanide
Cyanide does work.
For decades, cyanide has been used in gold processing throughout the world.
But the main problem is not the chemistry.
The problem is business risk.
Mining operations often face:
• sudden spike in cyanide prices
• supply disruptions
• late delivery
• increased transportation costs
• increasingly stringent regulations
A mine that is very profitable today could become not profitable when cyanide prices rise.
Additionally, the use of cyanide requires:
• tailings detoxification system
• additional security procedures
• special storage
• environmental monitoring
All this means additional costs and operational complexity.
Efficient mining operations require:
✔ stable chemical costs
✔ reliable supply
✔ simpler handling
Because of this more and more miners are starting to consider Sandioss as an alternative to cyanide.

Pay the Equivalent Price of 1 Drum of Cyanide
and Learn How to Run the Sandioss Process
Conversion Training at Mine Sites
Service fees
35 million IDR
This amount is roughly equivalent to price of one drum of cyanide.
But instead of buying chemicals that will run out, you invest in understand the processes that your own team can execute.
Once the training is complete, your operators will understand how to run the Sandioss process independently.
Simple Calculations for Miners
The training fee is equivalent to the price
≈ 1 drum of cyanide
Sandioss initial requirements
350 kg
This amount is roughly equivalent to working capacity of about 7 drums of cyanide only in many gold processing operations.
Simply put:
Pay 1 drum → learn how to run the equivalent capacity of 7 drums.
What Happens During the 3-Day Training
Our operators come directly to your mining site and work with your team.
This is not a theoretical training course.
This is a training course based on real-world processes.
During the training, you will learn:
✔ how to change the leaching process from cyanide to Sandioss
✔ the proper preparation and handling of Sandioss
✔ dosing and mixing procedures
✔ leach testing using your ore
✔ how operators can run the process independently
Once the training is complete, your team will understand how to run the Sandioss process safely and efficiently.
Required Preparations
Your mining operation should already have equipment commonly used in the cyanide process, such as:
• leach tank / barrel
• pump
• agitator or mixer
• filtration or sedimentation system
Sandioss can be used in existing processing systems.
Important
Sandioss cannot be used on materials that have been treated with cyanide.
You need to prepare:
• new / raw ore
Minimum Sandioss requirements for training:
350 kg
Costs and Responsibilities
Additional costs borne by the client:
• transportation
• accommodation
Client’s Responsibilities:
• Site safety
• Workplace safety
• Legal compliance and permits
Alternative: Small-Scale Training
If you would like to understand the process before implementing it at the mine, laboratory-scale demonstration training is available.
In this training, we process a 30–50 kg batch of ore together with you and demonstrate the entire Sandioss process flow.
Topics covered:
✔ Principles of cyanide-free gold leaching
✔ Sandioss preparation and dosage
✔ Process control
✔ How to optimize chemical costs
Training costs
32 million IDR
Requirements:
Purchase 5 bags of Sandioss
The Main Goal is Simple
Your mining profit should depend on:
✔ ore grade
✔ process efficiency
not on unpredictable cyanide prices.
With Sandioss, mining operations can:
✔ stabilize chemical costs
✔ reduce the risk of toxicity
✔ simplifies storage and handling
✔ maintain more profit from every gold production
Costs and Responsibilities
Additional costs borne by the client:
• transportation
• accommodation
