Paper Manufacturing — Retention Aid & Wet Strength
Paper mills add guar gum at the wet end of the papermaking process to improve fiber retention, boost wet strength, reduce drainage time, and give finished paper a smoother surface. Typical dose: 0.1–0.5% of pulp weight (0.5–5 kg per MT of paper). For specialty papers — writing/printing, tissue, filter papers, release liners — guar outperforms many synthetic retention aids on cost and biodegradability. Modern integrated mills producing 100,000+ MT/year of paper can consume 50–500 MT of guar annually depending on paper grade.
Ore Flotation & Mining
In mineral processing, guar gum serves as a depressant in flotation circuits — selectively suppressing the flotation of talc, graphite, pyrite and some iron minerals so target metal values (copper, nickel, platinum-group metals, molybdenum) separate cleanly. It is also used as a thickener in heap leach solutions and as a viscosifier in dense-media separation. Mining buyers typically specify high-viscosity, high-protein grades.
Slurry & Emulsion Explosives
Slurry and emulsion explosives — used in open-pit and underground mining, quarrying, and construction blasting — use guar gum as a gelling agent. The gelled explosive holds its oxidizer-fuel structure together even in wet drill holes, dramatically improving water resistance and detonation reliability. Usage: 0.5–2% of total explosive formulation. Guar is one of the primary natural gellants used across the global commercial explosives industry (Orica, MAXAM, NobelClad and others).

Frequently Asked Questions
What viscosity is best for paper manufacturing?
4000-5500 cps is standard for most paper mills. Specialty papers (tissue, filter, release liner) may require tighter viscosity bands or faster-hydrating variants. Discuss your pulp furnish and target paper grade with our team for a custom spec.
Can guar gum be used in acidic flotation circuits?
Standard guar loses some viscosity below pH 4. For acidic mineral flotation (e.g., some copper and gold circuits), we recommend carboxymethyl guar (CMG) or carboxymethyl hydroxypropyl guar (CMHPG) — these derivatives maintain performance in a wider pH range. Available on contract basis.
How much guar gum per MT of explosive formulation?
Slurry and emulsion explosives typically use 0.5-2% guar gum by total formulation weight. Exact dose depends on explosive type (watergel, emulsion, bulk ANFO blend), temperature range and target water resistance. Explosives chemists optimize this per application.
Do you supply derivatized industrial grades (HPG, CMG, CMHPG)?
Yes, on contract basis. Derivatized grades carry a 30-50% premium over standard guar and have longer lead times (45-60 days). For high-volume industrial buyers committing to recurring quarterly orders, we arrange dedicated production campaigns.
What's the minimum order quantity?
One 20ft FCL (18-20 MT) is standard for new buyers. Established industrial buyers typically order 2-5 FCL per shipment or set up long-term supply agreements with monthly tonnage commitments.
