Gold Extraction With Electrochlorination

The ClorTec® Gen III On-site Sodium Hypochlorite generator produces a 0.8% solution of sodium hypochlorite which has been used and proven as an alternative to the conventional method of extracting gold with cyanide in the mining industry. CECHLO® systems generate up to 12.5% hypochlorite solution for larger applications, which can reduce the volumes of hypochlorite required.

The mining industry is under growing pressure to develop environmentally safe and friendly processes that do not produce toxic liquid effluent. The use of cyanide has been conventionally used in the extraction of precious metals, but the toxicity of cyanide has forced several global mining jurisdictions to eliminate or reduce its use. Sodium hypochlorite solution produced on-site is the most economical and safe alternative.

Why ClorTec?

Why ClorTec?

The ClorTec Gen III is modular with an optimized footprint and can be configured to deliver the large capacities of sodium hypochlorite typically required for mining applications. 

  • The ClorTec Gen III produces a low concentration (0.8%) of non-hazardous sodium hypochlorite solution which can be used in the process of extracting of gold without producing toxic liquid and affect the environment. 
  • The ClorTec Gen III uses non-hazardous precursors – water, salt and electricity. 
  • The ClorTec Gen III offers the highest efficiency in salt consumption which translates into 15% salt cost savings.

Why CECHLO?

CECHLO-M-NS-1

CECHLO MS Generators can generate up to 12.5% sodium hypochlorite from delivered salt.  For large applications, this can greatly reduce chemical solution volumes, reducing pump and pipe sizes.

  • Safely and economically produces chlorine gas (Cl2), sodium hydroxide (NaOH) and high-strength 12% sodium hypochlorite (NaClO) without the risks associated with delivery or storage of hazardous chemicals such as high-pressure chlorine 
  • More than 40 years of experience and improvement of ion exchange membrane electrolysis technology 
  • Long, stable operation and easy maintenance, with world-proven ion exchange membrane electrolyzer
