BACTECH ENVIRONMENTAL CORP

About the Company:

BacTech Environmental Corporation (“BacTech”) is a proven environmental technology company, delivering effective and eco-friendly bioleaching and remediation solutions to commercial operations to process and recover preferred metals (gold, silver, cobalt and copper) and safely remove and transform harmful contaminants like arsenic into benign EPA-approved products for landfill. Tapping into numerous environmental and economic advantages of its proprietary method of bioleaching, BacTech uses naturally occurring bacteria, harmless to both humans and the environment, to neutralize toxic mining sites with high-pay potential.

BacTech’s bioleaching process liberates precious and base metals from difficult to treat and generally harmful ores, concentrates, and tailings. BacTech's environmentally friendly processing benefits extend beyond the remediation of tailings and other mining stockpiles. Their solution strikes balance and considers benefits towards the planet, people, and profit.  

BacTech plans to build a new owner-operated bioleaching facility near Ponce Enriquez, Ecuador, in a region where arsenic is associated with gold ore (Arsenopyrite). The Company plans to build a 50 tpd bioleaching plant to treat high gold/arsenic material. A 50 tpd plant, processing 1.95 ounces of gold per tonne of feed, similar to feeds available to the Company from local miners, would produce approximately 30,900 ounces per year. Plant designs are modular and can be expanded without affecting ongoing production. The total concentrate market in the Ponce Enriquez area is estimated to be between 200 and 250 tonnes per day, allowing for increased potential with a larger plant.

The Technology:

  • Conventional gravity/flotation to remove sulphides from ore/tailings to make high-grade gold/arsenic concentrate

  • Sulphides are the source of acid release but also contain the valuable metal to be recovered

  • Bioleaching of arsenopyrite (arsenic/sulphide ore) concentrates produced from mining and/or tailings

  • The technology is commercially proven

  • BacTech has “in-house” capacity for the design, construction and operation of the plant

  • It is a continuous process which is safe, easy to operate and flexible

  • Scalable in a short period of time and capable of processing a wide variety of low to high grade concentrates
