Real-time monitoring of As and Cd in a weak acid effluent

8

  • LIBS system was installed at the Glencore Horne smelter located in

Rouyn‐Noranda, Quebec, Canada.

  • It provides real time analysis for arsenic (As) and Cadmium (Cd) in weak

acid solution at 80 C prior to neutralization/precipitation step.

Real-time and direct analysis of slurries with no sample preparation

  • LIBS measurements carried out in

real time on a bypass from the slurry line.

  • LIBS system installed at nickel mine site

for real time analysis of nickel ore slurry (Mg, Ni, Si, Fe, Al, Mn, etc.) prior to smelting (Thompson, Manitoba).

  • LIBS system installed at Liberty mines,

Ontario, Canada for monitoring Mg and Ni in nickel ore slurry prior to smelting.

  • LIBS system installed at site to provide

continuous composition analysis (C, Ca, Mg, Al, Si) of the slurry prior to filtration and pelletizing. Quebec, Canada).

  • Oil sands: processed water and bitumen content
  • Nickel, Aluminum, Gold, Copper and Iron: prospection, ore slurries, refining

Mineral processing/ smelting process

  • Molten metals: Aluminum, Copper, Nickel, Zinc, Lead

molten electrolytes and Steel.

  • NRC team succeeded to implement the technology for

the first time to monitor 24/7 the chemical composition of molten metal.

  • 30 LIBS systems installed worldwide in automotive

industry for monitoring molten zinc.

  • For the first time, NRC team and its licensee obtained the accreditation ISO 17025 for

the LIBS method for soil analysis.

  • Analysis time is 1 minute per sample instead of 24h by conventional technique

Unique Proposition for NRC LIBS for Mining Applications

Feature So what? Photon counting for detection and fiber laser for generation

  • Low cost of system and ownership
  • Better sensitivity (LOD 10 ppb)
  • High sampling speed as 1000,000

samples/s. It takes 1 s to sample 1m2

  • Robustness for site conditions and harsh

environments.

  • Lifetime of laser head 11.5 years 24/7

Advanced chemometrics tools Already adapted to mineral ores, soil and oil sands Application methods Enable industrial use No gas shielding required Quantitative analysis of major, minor and trace elements Able to detect extremely low concentrations Access to bulk through successive shots of combination of 2 laser pulses Can penetrate contaminated surfaces that may not be representative of the bulk

Mining applications

  • LIBS has features and capabilities to be applied at

different stages of the mining value chain.  At line for fast analysis  On-line analysis  Standoff Analysis  Low cost of ownership  Robustness

  • Challenges for mining LIBS:

 Representative Sampling  Surface analysis vs bulk

Conclusions

  • LIBS opens new ways for fast and direct determination of

chemical quantities for mining applications.

  • LIBS can be applied and used for real time analysis at

different stages of the mining cycle and oil sands processing from exploration to finished products.

  • The advent of new detectors, lasers and spectrometers
  • pen

new

  • pportunities

for the LIBS in mining applications.

  • The sampling and surface vs bulk analysis are issues but

it can be resolved through different approaches that are currently under study.
