:: Gekko Supplies Cyanide Detox System for Phoenix Gold Project


Rubicon Minerals Corporation is an advanced-stage gold development company focused on the environmentally sustainable development of its high-grade Phoenix Gold Project in Red Lake, Ontario. Gekko Systems is pleased to be supplying a complete turnkey Cyanide Detox System, designed to reduce cyanide in the plant discharge to less than 1ppm weak acid dissociable (WAD) cyanide using liquid sulphur dioxide (SO2) and oxygen generators for the detoxification process.

The supplied plant will include the cyanide destruction tank, liquid SO2 handling, storage and dosing systems, oxygen generation system and process control instrumentation.

Gekko Systems is a company dedicated to improving processing outcomes for the mining industry, with a particular interest in capital-effective, low environmental footprint plants. Over the past 10 years the company has been instrumental in developing and applying alternative, low-energy flowsheets using gangue rejection and pre-concentration concepts to minimise comminution.

In early 2012 Gekko's Technical Team created a Cyanide Detox Group in conjunction with Randy Agius, the knowledge leader in this field. Work undertaken by the Gekko Cyanide Detox Group won the 2012 Mining Magazine's Environmental Excellence Award.

"Gekko's experience gives us great confidence in the successful design and operation of this critical process ensuring we continue a responsible and environmentally sustainable development," said Dan Labine, Vice President of Operations for Rubicon.

Gekko draws on proven technologies and methods for detoxifying cyanide, including SO2/O2, peroxide and Caro's Acid processes. The company understands the benefits and pitfalls of each detox method and will be providing specialist knowledge in the development of the Phoenix Gold plant design. Gekko provides a full range of client support from test work, design and supply to commissioning and process optimisation to ensure the best possible outcome.
