Uniform solution distribution
Pressure-compensating emitters and full-pad coverage deliver lixiviant where the ore actually sits — instead of channelling through hot spots.

Proven field outcomes
Where the gains come from
The numbers below are not marketing — they are reported by operators after they converted from sprinklers or conventional drip to Ore-Max heap leach systems. Three design choices do most of the work.
Pressure-compensating emitters and full-pad coverage deliver lixiviant where the ore actually sits — instead of channelling through hot spots.
Mining-grade emitters with oversized screens and turbulent flow paths keep dripping in iron, gypsum, and grit chemistries that close conventional emitters down.
Drip collars and pressure regulators let operators leach side slopes and steep terraces that sprinkler systems leave behind — recovering ore most pads stop charging for.

Featured case studyGold Mining
After Max-Emitter conversion in 2003 at a major South American gold mine, 7 consecutive monthly production records were set. First quarter 2004 results confirmed a 26% gold extraction increase compared to pre-Max-Emitter performance.

Ore-Max heap leach systems are running in North America, South America, Africa, Asia, and Australia — in climates from the Atacama to the Arctic Circle. The case studies above are a sampling of the operating record.
Why the results look this way
