Eco-Goldex (Eco-Gold Extraction) is a Canadian company that supplies its Eco-Goldex ® brand reagent series for gold/siver ores leaching in gold mine operations and gold/silver/PGM stripping in E-waste materials recycling operations.
Eco-Goldex reagent series is characterized by their low toxicity while keep the same or similar gold extraction capacity as cyanide。 Eco-goldex is the next generation of gold extraction and be an alternative of sodium cyanide in gold extraction business including gold mining and E-waste recycling.
Eco-Goldex has expanded its product series to five different types to cover the most common and demanded commodity processes:
Eco-Goldex O-Series is suitable for most common gold ores such as oxide, semi-oxide, and non-refractory sulfide gold ores. It is applicable to heap leach, CIL/ CIP, VAT leach methods...
Eco-Goldex E Series is a specially formulated reagent for gold stripping from E-waste and old jewelry materials recycling.
The C-Series product is a specially formulated and developed reagent aiming to treat complex gold ores. This type of complex ore is usually referred as refractory gold ore, and are characterized by high contents of carbonaceous matters, ultra-fine (sub-microscope) gold grains locked in sulfide minerals such as pyrite, arsenopyrite, stibnite.
Though Eco-goldex O series still works very well on many silver ores, Eco-goldex developed a new reagent (Os series) specifically for solver ores or silver dominant dominated Ag-Au ores with the goal of better silver leaching performance. This reagent can process oxide or sulfide silver ores.
The Es reagent is specially formulated for silver stripping in silver plated Scrap metals. The Es stripping reagent is composed of three agents:A, B and C. This reagent works in alkanic condition, and silver is recovered directly through reverse electroplating method.
Eco-Goldex E / Es product series have a unique feature that it can selectively strip surface gold/silver from plating electronic parts such as pins, connectors, RAM, CPU and PCB, while other metals like copper, aluminium are not or only slightly attacked.
This selective stripping feature makes gold stripping process much easier and simplifies E-waste recycling processes into separate steps in which specific metals are separated and recovered.
