Eco-Goldex (Eco-Gold Extraction) is a Canadian company that dedicats to develop and supply its innovative Eco-Goldex ® technology and products of precious metal (Au, Ag, Pd...) extraction in gold mining and E-waste materials recycling business.
Eco-Goldex's mission is to provide its simple, high performance and eco-friendly product to global users in gold extraction operations including gold mining and E-waste recycling.
Eco-Goldex proudly provide products and services to its clients from more than 48 countries that cover all the continents.
Eco-Goldex has developed and commercialized the following product series:
The O Series (it refers to Ores) is specially formulated and manufactured with the purpose of replacing the toxic sodium cyanide in gold/silver/PGM rock ore leaching.
The O series can compete sodium cyanide easily in most rock ore processing including gold leaching rate (similar or even better), agent consumption (similar or slightly higher) and leaching time (similar or even quicker); but the most advantage of the O series is it is low toxic and is classified as ordinary goods and can be purchased, transport, storage and usage without restriction.
Eco-Goldex O Series is suitable for most common gold ores such as oxide, semi-oxide, and non-refractory sulfide gold ores or oxide copper ores.
The O series share the same flowsheet with cyanidation, it can seamlessly replace cyanidation without change of existing operation system and is applicable to heap leach, Carbon in Leach / Carbon in Pulp, VAT leaching methods...
For most large e-scrap recyclers, the most common solution of precious metal recovery is selling e-scrap materials to one of the few large smelters in the world, and the smelters apply pyrometallurgical method (burning everything in furnace) to process these e-scraps and give the recyclers credits after many discounts and management fee charges. These recyclers only get a small fraction of the precious metal values in the e-scraps they sold to these large monopoly smelters.
Precious metal recovery through pyrometallurgical approach (Smelting) is not practical for small-medium scale recycling companies due to the facts of:
Understood these facts and the desires of recovery Au/Ag/Pd by themselves of these small-medium sized e-scrap recyclers, Eco-goldex has developed an hydrometallurgical (in water solution) method that can selectively extract precious metals (Au, Ag, Pd, Pt, In, Ir…) from e-scraps in a very simple and effective approach. Users with simple training can do the job without professional background requirements.
More importantly, eco-goldex provides flexible system/ flowsheet that allows clients to extract what they want based on their situations:
Eco-goldex’s technology/system can fit any operational scale from gold stripping hobbyist to recycling company with a daily process capacity of up to 50 tons. With less than 40,000$ investment, a 1 ton/day stripping/recovery system can be constructed.
Eco-Goldex E Series is a specially formulated chemical compound for gold stripping from E-Scraps and old jewelry scraps recycling. The E seris is characterized by its outstanding stripping speed and high performance in plated gold materials; more importantly, the E series stripping solution can strip multiple precious metals including Au,Ag,Pd from E-scraps.
Eco-Goldex has developed its propreitary two-stage precious recovery technology that can recover up to 99.6% gold from pregnant solution.
The simplicity of stripping process and high precious metal recovery rate make the Eco-goldex E series and its packages fit users with different skills and capacities from hobbyists to small scale E-scrap recycling operators to large scale recycling enterprises.
Eco-Goldex E product series have a unique feature that it can selectively strip precious metals (Au, Ag, Pd, Pt...) from plating electronic materials such as pins, connectors, RAM, CPU and PCB, while other metals like copper, nickel, aluminium are not or only slightly attacked.
This selective stripping feature makes precious metal stripping process much easier and simplier in E-waste recycling.
Eco-Goldex's proprietary technology of electrowinning + Active Carbon (AC) adosrption method warrants over 99% gold recovery rate in E-scrap pregnant solution. Eco-Goldex claims that the extraodinary high stripping efficiency and gold recovrey rate of Eco-goldex E agent making it stand out among its competitors in the market.
