Flexicone technology for sulfide ores flexicone

Iodine-iodide technology for leaching gold, silver and palladium from ores and concentrates. We have developed an iodine-iodide technology for leaching gold in an environment with a pH of 4-9. This technology is versatile and makes it possible to operate the system in less corrosive conditions with a lower iodine concentration.

It Started With An Idea New Gold Recovery

This “modern” placer technology only recovers up to 40% of the gold from every ton of ore concentrate (finely ground ore) as it primarily targets nuggets and flakes of gold. The remaining 60% goes untouched. New Gold Recovery’s system recovers approximately 90% of the gold present per ton of concentrate, a fact which has been verified by ...
