Mine Water Online Analysers

 

The use of water in mining has the potential to affect the quality of surrounding surface water and groundwater. In response to environmental concerns and government regulations, the mining industry worldwide increasingly monitors water discharged from mine sites, and has implemented a number of management strategies to prevent water pollution. Water issues and management vary from site to site and must be addressed locally.

lagoa_vermelha_na_mina_do_losal_05

How mines use water

Mining operations use water for mineral processing and metal recovery, controlling dust, and meeting the needs of workers on site. The amount of water required by a mine varies depending on its size, the mineral being extracted, and the extraction process used. For instance, metal mines that chemically process ore to concentrate metals such as copper and gold use much more water than non-metal mines such as coal, salt, or gravel mines.

Although a large mining operation may use a considerable amount of water, the minerals industry overall consumes a relatively small quantity of water at national and global levels. Mining accounted for 4% of the water used in Canada in 2005, versus 60% for coal and nuclear electric power generation, 18.5% for manufacturing, 9.5% for municipal water supplies, and 8% for agriculture. Mining accounts for 1% of water used in the U.S., and 2-3% of the total water consumed in Australia.

The rate of water reuse and recycling in mineral processing is often very high at mine sites, especially in areas with arid climates. A number of innovative water conservation practices  are being developed and implemented to reduce water use.

Types of mine water

There are a number of classifications of mine water, which can vary in their quality and potential for contamination:

  • Mine water: refers to any surface or groundwater present at the mine site
  • Mining water: water which has come into contact with any mine workings
  • Mill water: water used to crush and grind ore, may contain dissolved minerals and/or metals
  • Process water: water used in the chemical extraction of metals, commonly contains process chemicals
  • Leachate: water which has trickled through solid mine wastes and may contain dissolved minerals, process chemicals, and/or metals
  • Effluent: Mining, mill, or process water which is being discharged into surface water, often after being treated
  • Mine drainage water: Surface or groundwater which flows or has the potential to flow off the mine site

Typically, all the mine water at metal mines is collected and stored in tailing ponds before being treated and released to surface water if necessary.

Discharge management

OPAL-OIl Pollution Alarm - WQMS

Oil platforms, refineries and Tank farms generate produced water which requires close management. For every country in Oceania, there are regulations setting limits on the amount of hydrocarbons than can be disposed of overboard and a range of different lab techniques that can be used for reporting this amount. The OPAL and PAUTBAC II from SERES IR based analysers can provide continuous measurement of the oil concentrations in the discharge water from oil and gas processing and storage facilities.

Process optimisation


The OPAL and PAUTBAC II from SERES are respectively side stream analyser and oil tank de-watering systems based on IR light scattering. They not only can provide you with extremely accurate monitoring, but also sense for changes in the size of oil droplets and therefore in process conditions. Using the built in IR detector, the OPAL and PAUTBAC II analysers enable early detection of oil traces in all type of water, ensuring fast overview of the process conditions.
As the volume of your discharge water increases, you need a system that will meet your changing demands, work reliably and with minimal operator input required. Having provided hundreds of online monitoring systems worldwide, SERES is the best positioned to assist you along with your water management plan.

OFCEAS & Low Pressure Sampling

Continuous Emissions Monitoring and Process Control

Starting in 2012, AP2E launched the industrialisation of the ProCeas® and LaserCEM® product range, the continuous and multigas analysers using OFCEAS* patented laser spectrometry. This analyser range is based on several innovations, providing very high performance in terms of response time (less than a few seconds) and great accuracy of the analyses (wide dynamic range from ppb to %):

OFCEAS, CONTINUOUS INFRA-RED LASER SPECTROSCOPY TECHNOLOGY

The ProCeas® and the LaserCEM® are based on the OFCEAS coupled to a Low Pressure Sampling LPS (100 mbar absolute) developed and patented worldwide by AP2E (France), for the online analysis of several key gases in industrial, environmental and OH&S applications. It provides measurements with a very high spectral resolution in addition to an analysis system with a simplified sampling (no heated line nor treatment of samples) and an interference-free, fast and sensitive analysis, regardless of the matrix of the gas to be analysed.

ProCeas

The OFCEAS technology essentially differs from the CRDS (Cavity Ring Down Spectroscopy or Spectroscopy by resonance damping time) technology by its feedback principle: a part of the emitted radiation is returned from the chamber to the laser, enabling the tuning of the laser and the cavity resulting a resonance phenomenon. With a volume of only 15 cm3, the measuring cavity or cell is equipped with mirrors whose reflectivity exceeds 99.99%, providing an optical path between 1 and 10 km (approx. 10 meters in conventional technologies). The immediate consequence of this phenomenon is the identification of very intense absorption peaks with a very narrow spectral width. Given that the source used is a continuous laser, the system presents very high measurement stability: there is no zero drift and no need for new calibrations.

LOW-PRESSURE SAMPLING SYSTEM

The Low Pressure Sampling (LPS) System allows reducing the sample dew point (vapour pressure) to prevent the risk of condensation. The sampling method is achieved by the use of a sonic nozzle which allows reducing the sampling pressure down to 100 mbar. In these conditions the ambient temperature is almost always above the dew point eliminating the risk of condensation.

r4

  • No Sample heated line required to eliminate condensation: low power consumption, no related ongoing maintenance
  • True Direct Extractive CEMS/Process analyser (no dryer or scrubber)
  • No risk of absorption/desorption typical of high SO2/SO3 application
  • Low pressure accentuate the gas finger print
  • Cost effective multipoint monitoring
  • Standard system comply with ATEX standards

The integrity of the sample is therefore ensured. The very low airflow ensures a verylow response time and a minimal contamination of the system.

OFCEAS Detection limits

All these points enable to both increase the detection sensitivity and  simultaneously reduce the noise, which permits the detection of gases at very low levels of sensitivity (traces of H2S – LOD under 50 ppb, or traces of H2O – under 1 ppm).

ProCeas

Complete pre-calibrated multicomponent (H2S, CO, CO2, H2, H2O, HCl, HCN, HF, N2O, NH3, O2 and CH4) laser Infrared Spectrometer designed for online monitoring of combustion process, natural gas (LNG), pure gas (trace) and ambient air (trace).

 

LaserCEM

The LaserCEM is a complete pre-calibrated multi-component (NO, NO2, NOx, SO2, CO, HCl, CO2, H2O, H2S, NH3, N2O, COS, SO3, CH4, HF) laser Infrared Spectrometer designed for Continuous Emissions Monitoring and compliant to standard EN 15267-3 : 2008 and QAL 1 de EN 14181 . With the announcement of the continuous measurement of SO3 (sulphur trioxide) at the exit of combustion units, AP2E represents the link from an industrial point of view between regulatory measurements (EMC) and optimizing production processes. If SO2 is now properly measured, it does not fully reflect the sulphur emissions from combustion units subject to this requirement. In the presence of oxygen, SO2 does in effect form sulphur trioxide (SO3), a gas that is much more corrosive than SO2. And other chemical phenomena occur, particularly in de-nitrification (DeNOx), which in the presence of ammonia may lead both to an over-consumption of ammonia and to filter blockages. Not measuring SO3 entails the under estimation of sulphur emissions, and also additional maintenance costs and over-consumption of reagents. To have continuous and precise knowledge of the SO2 / SO3 couple enables the operator to choose the controlling conditions for limiting the formation of SO3 and its indirect costs.

*Optical Feedback Cavity Enhanced Absorption Spectroscopy: technology developed and patented by the University Joseph Fourier (France), coupled to a Low Pressure Sampling (100 mbar absolute) developed and patented worldwide by AP2E, for the on-line analysis of different gases. By the end of 2010, after two years of R & D studies, the AP2E ProCeas® was the award recipient of the USA “R & D 100” which rewards the 100 most innovative global technologies of the year.
