Chemical recovery
Scrap and concentrate are leached and purified. The liquor is crystallised into ammonium paratungstate.
Scrap and concentrate. One plant. Finished powder.
A greenfield recycling plant in the Pax Silica Economic Zone, Tarlac. Hard-metal scrap and mine concentrate become APT, then tungsten powder and carbide. The Philippines has no such plant today.
Two feeds into one metallurgy path.
~$127MIllustrative plant capital
~4,000 t/yFeedstock design capacity
~2,130 MTFinished powder and carbide
Phase 2Optional secondary recovery
There is no tungsten processing capacity in the Philippines today. CanPac is designing a greenfield plant to recover tungsten from hard-metal scrap and from mine concentrate. The two front ends meet in one downstream process, so a single plant can take both feeds.
Design capacity is about 4,000 tonnes of feedstock a year, with finished powder and carbide on the order of 2,130 metric tonnes. Illustrative capital is about $127 million, at the top of the stated range for chemical smelting to APT, concentrate co-processing, arsenic stabilisation, powder metallurgy, and civil works.
A later option, about $22 million, would recover molybdenum, tin, and indium. That tranche waits until Canadian concentrate is available. The engineering can be finished earlier so the modules are ready when needed.

From feed to press-ready powder
Arsenic control
A dedicated line captures airborne arsenic and fixes residues as scorodite, then as a cement-solidified product.
Powder metallurgy
APT is reduced to tungsten metal, then carburised to tungsten carbide for tooling and wear parts.
Ready-to-press
Carbide is milled with binder and dried into the spherical grades industrial buyers already purchase.
Products
The grades industrial buyers already buy
Scrap and concentrate become ammonium paratungstate, tungsten powder, carbide, and ready-to-press grades for industrial tooling and specialty uses.
- APT as the chemical intermediate
- Tungsten powder for fabrication and alloying
- Carbide and press-ready grades for hard-metal buyers
Intended products
One downstream path, from recovered tungsten units to press-ready powder.
- Ammonium paratungstate (APT)The intermediate chemical from recovered tungsten units.
- Tungsten powder (W)Metal powder for fabrication and alloying.
- Tungsten carbide (WC)Hard-metal feedstock for tooling and wear parts.
- Ready-to-press gradesPress-ready powder of the kind industrial buyers already purchase.
Build
Greenfield capacity where none exists
The plant is designed as greenfield powder metallurgy in Pax Silica, built at the same time as the waste facility. Concentrate from Mount Pleasant would be optional feed, and only if a dedicated upstream path opens.
- No tungsten processing plant in the Philippines today
- Built in parallel with the waste facility
- Canadian feed is optional, not a condition
