More about the TAC and WAD

TAC on-line cyanide analysers have been successfully used to control free cyanide in the Gold/Silver leach process for over twenty years.

The TAC analyser introduced in 1992 was the first unit to achieve sustained operation of closed loop cyanide addition control. TAC addressed the three basic problems that had plagued earlier equipment: reliable sampling, accurate analysis and advanced cyanide dosing control strategy.

TAC analyzers users see cyanide savings and improvement in recoveries. Plants with TAC analysers show both lower and more consistent cyanide levels in tailings.

The latest TAC 1000 model is the third generation in the TAC analyzer series.

WAD 1000 on-line weak acid dissociable cyanide (CNWAD) analysers have been used to monitor and control WAD cyanide in the Gold/Silver tailings since 2004.

The WAD 1000 assists plants in meeting residual cyanide targets in tailings as per local regulations or cyanide code compliance. Many units are used to control cyanide detoxification processes.

The WAD 1000-S analyzer ensures code compliance, reduces cyanide destruction process operating costs and forms a historical record of CNWAD values in tailings.
