High-purity lead oxide and mining reagents, delivered with precision and consistency. 18 years supplying mining and metallurgical operations.
GGI Chemicals Group is a direct manufacturer of high-purity lead oxide (litharge), producing it at our own lead mine and processing facility located in Hebei, China. For 18 years, our focus has been consistent: high-purity raw materials, delivered with the precision and consistency mining and metallurgical operations require.
To offer a complete portfolio of solutions for the mining industry, we also commercialize a range of mineral processing reagents — fire assay flux, sodium isopropyl xanthate, potassium ethylxanthate, potassium amyl xanthate, sodium sulfide, sodium hydroxide, and lead nitrate — used in flotation and assay processes, including gold recovery.
Eighteen years in this industry means we understand what operations require from a chemical supplier: consistent purity, dependable supply, and a partner who treats reliability as non-negotiable. That is the standard we hold ourselves to on every shipment.
Exact technical grades for mining and industrial production.
High-purity yellow-to-red PbO, manufactured in-house for fire assay flux and flux-grade use.
Strong alkali for pH control and ore leaching, supplied as flakes, pearls, or solution.
pH control & neutralization; ore leaching (gold cyanidation, alumina refining); base input for soap, detergent, and pulp production.
Ready-to-use litharge, borax, soda ash, silica and reducing agent blend for fire assay fusion.
Fusing crushed ore samples; cupellation preparation; precious metal grade determination.
Balanced xanthate collector for Cu, Pb, Zn and Au-bearing sulfide flotation.
Sulfide ore flotation (Cu, Pb, Zn, Au-bearing sulfides); default collector for base-metal flotation circuits.
Short-chain xanthate built for selectivity — the choice for cleaner and finishing stages.
Cleaner / finishing-stage flotation; copper and lead sulfide flotation.
Reactivates oxidized Cu, Pb, and Zn mineral surfaces ahead of xanthate flotation.
Sulfidizing oxidized mineral surfaces; leather tanning; pulp/paper processing; heavy-metal precipitation in wastewater treatment.
Water-soluble lead salt used to activate cyanide gold-leaching circuits.
Gold-leaching circuit activator; mineral processing and chemical synthesis applications.
The strongest xanthate collector — built for maximum recovery on oxidized sulfide surfaces.
High collecting-power flotation; oxidized/tarnished sulfide surfaces; gold recovery from sulfide ore.
Practical answers from the field.
SIPX, PEX, or PAX — how selectivity and collecting power should drive your reagent choice.
From fusion to cupellation, the chemistry behind the lead button assayers rely on.
Recovering value from oxidized copper and lead surfaces before flotation begins.
Cyanide leaching only works in a narrow pH window — here is where caustic soda fits in the circuit.
A small lead nitrate addition can measurably lift gold recovery on sulfide-bearing ore — here is the mechanism.
A quick-reference comparison of the three xanthate collectors GGI Chemicals supplies, and when each one is the right call.
The chemistry is identical; the physical form is what determines how well it fits your dosing system.
The same reagent that reactivates oxidized sulfide minerals also pulls dissolved heavy metals out of process water.
Fire assay lives or dies on consistency — here is what changes when a lab switches from mixing flux in-house to a pre-blended supply.
A practical checklist for evaluating a Chinese chemical supplier — beyond just comparing price per tonne.
