Skip to content Running a mineral processing plant in Australia isn’t easy. Between tight budgets, delayed shipments, and the pressure to keep production running, every dollar matters. The right mineral processing reagents make a huge difference—but many plants pay far more than necessary on bulk orders.
Below are seven key chemicals every large-scale operation needs—plus a smart way to save thousands through direct bulk purchasing.
1. Xanthates (Collectors)
Purpose: Xanthates are flotation collectors that make valuable minerals attach to air bubbles, separating them from waste rock.
Usage: 50–200 grams per ton.
Bulk Tip: BenXin tests every xanthate batch before shipment to ensure consistent flotation results and stable performance.
2. Frothers (MIBC and Pine Oil)
Purpose: Frothers such as MIBC and Pine Oil create the bubbles needed for flotation.
Usage: 10–30 grams per ton.
Bulk Tip: Standard drum packaging ensures flotation circuits never run dry—ideal for continuous production lines.
3. pH Modifiers (Lime and Soda Ash)
Purpose: pH modifiers keep flotation systems stable and efficient.
Cost: Lime costs around $150–250 per ton in bulk. Soda ash provides smoother pH control for larger batches.
Bulk Tip: Jumbo bags cut handling time and shipping costs.
4. Depressants (Sodium Cyanide and Zinc Sulfate)
Purpose: Depressants prevent unwanted minerals from floating during separation.
-
Sodium cyanide for gold recovery.
-
Zinc sulfate for lead-zinc separation.
Usage: 50–500 grams per ton.
Bulk Tip: Safe, compliant packaging ensures uninterrupted gold processing.
5. Flocculants
Purpose: Flocculants speed up solid-liquid separation in tanks and ponds, cutting settling time by up to 50%.
Usage: 5–50 grams per ton.
Bulk Tip: Test small samples before placing large orders to avoid waste and optimize performance.
6. Activated Carbon
Purpose: Used in CIP/CIL gold recovery systems, activated carbon captures gold from leach solutions.
Cost: $2,000–3,500 per ton. Can be reused 6–8 times.
Bulk Tip: Smart jumbo packaging reduces delivery frequency and transport cost.
7. Grinding Aids
Purpose: Grinding aids improve mill efficiency, cutting power use by 5–15% and boosting throughput.
Bulk Tip: Stock up in advance to lower energy bills and maintain consistent milling performance.
💬 Why Most Buyers Overpay — and How to Stop
Here’s the truth: most Australian chemical suppliers buy from China, add their markup, and pass that extra cost to you.
BenXin takes a different approach—direct sourcing from verified manufacturers. That means no middlemen, no hidden margins, and transparent pricing straight from the factory.
You get:
-
Certified, tested reagents
-
Steady bulk supply for large operations
-
Factory-direct savings
