What mineral processing and mining additives does LigninCorp supply?
LigninCorp supplies mineral processing and mining additives for mineral slurry dispersion, particle binding, fines control, haul road dust suppression, stockpile treatment, pelletizing and material handling support. Key product families include sodium lignosulfonate, calcium lignosulfonate, magnesium lignosulfonate, Dispersant NNO, Dispersant MF and lignosulfonate dust-control grades. Buyers can use this page to match mining requirements with product families, prepare TDS, SDS/MSDS and COA requests, and send ore or site conditions for grade recommendation.

How are lignosulfonates dosed in mineral processing?
As a slurry dispersant, calcium lignosulfonate dispersant grade typically starts at 0.1–1.0% of the solids, added with the process water while stirring. In flotation and fine-ore slurries the useful dose is usually much lower and is found by laboratory testing on the ore. Our technical data sheets give the dispersant range; the flotation and slurry figures below are published practice for orientation only.
| Use | Typical starting dosage | Source and notes |
|---|---|---|
| Slurry dispersion (calcium lignosulfonate, dispersant grade) | 0.1–1.0% of solids | Our TDS. Add the powder to the water while agitating; adjust by solids loading and viscosity target. |
| Iron ore slurry thinning | About 0.05–0.2% of solids | Published practice. Viscosity can rise again above about 0.4%. |
| Flotation depressant | Tens of grams per tonne of ore | Published practice. Selectivity can drop at the high end; set by laboratory flotation tests. |
| Pellet and briquette binder | See the binder page | Covered on Industrial Binder. |
| Haul road dust control | See the dust control page | Covered on Dust Suppression. |
How to add it
- Make a solution: dissolve the powder in process water to a known strength so it can be metered accurately.
- Dose at the right point: add slurry dispersants before grinding or pumping; add flotation depressants in the conditioning tank before the collector.
- Find the minimum: run viscosity or flotation tests at several doses and use the lowest dose that reaches the target.
Points to check
Lignosulfonates are surface-active and can add froth and raise water recovery in flotation. Their effect depends strongly on ore mineralogy, water hardness and pH, so results from one ore do not transfer directly to another.
Trial checklist
- Slurry viscosity or grade and recovery at each dose
- Froth behaviour and water recovery
- Compatibility with collectors, frothers and lime
- Cost per tonne of ore treated
What details help LigninCorp recommend a mining additive?
- Application type, such as mineral slurry, ore processing, haul road, stockpile, pelletizing, briquetting or material handling.
- Target function, including dispersion, binding, dust suppression, fines control, slurry stability or handling strength.
- Ore or mineral type, solids content, pH, water quality, particle size and process temperature.
- Traffic level, road material, moisture condition, dosage target, application method and performance benchmark.
- Required documents such as TDS, SDS/MSDS, COA, specification sheet or sample request.
- Packaging, order quantity, destination country and shipment timeline.
Mineral Processing and Mining Additive FAQs
How are lignosulfonates used in mining?
Lignosulfonates may be reviewed as dispersants, binders and dust suppression additives in mineral slurry processing, haul road treatment, stockpile management and selected pelletizing or briquetting operations.
Can LigninCorp support mining haul road dust control?
Yes. LigninCorp supplies calcium lignosulfonate, sodium lignosulfonate and dust-control grades for mine haul roads, industrial yards, stockpiles and unpaved road surfaces.
Which products support mineral slurry dispersion?
Sodium lignosulfonate, Dispersant NNO, Dispersant MF and selected wetting-dispersing agents may be reviewed depending on ore type, solids content, pH, water chemistry and slurry stability target.
What documents are useful before sample testing?
Buyers commonly request TDS, SDS/MSDS, COA, packing information and application notes before lab or field evaluation. LigninCorp can prepare document support according to the selected mining or mineral processing additive family.
What is the typical lignosulfonate dosage in mineral slurries?
Calcium lignosulfonate dispersant grade typically starts at 0.1–1.0% of the solids. For fine-ore slurries and flotation the useful dose is often much lower, so it is set by laboratory tests on the actual ore.
