TOPAZ Cerium – Rare Earth

Rare Earth

rare earth element (REE) or rare earth metal (REM) is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties.

Despite their name, rare-earth elements are relatively plentiful in Earth’s crust, with cerium being the 25th most abundant element at 68 parts per million, more abundant than copper. They are not especially rare, but they tend to occur together in nature and are difficult to separate from one another. However, because of their geochemical properties, rare-earth elements are typically dispersed and not often found concentrated as rare-earth minerals in economically exploitable ore deposits.

Uses of Rare Earth ElementsRare earth metals and alloys that contain them are used in many devices that people use every day such as computer memory, DVDs, rechargeable batteries, cell phones, catalytic converters, magnets, fluorescent lighting and much more.

Most of us use rare earth elements every day – without knowing it. These little-known and fascinating elements make modern electronics possible.

Mining Rare Earth

Rare Earth Minerals Processing. There are two major REE ore minerals from which predominantly LREE can be extracted with relative ease: bastnaesite and monazite. Bastnaesite, a fluorocarbonate mineral and monazite, a phosphate, contain predominantly either cerium, lanthanum or yttrium.

The run of mine material is passed through a cascade of physical processing steps including crushing, screening, grinding and flotation finally producing a bastnaesite pre-concentrate from which products with different REO contents are derived in subsequent thermal and chemical processing steps.  The REE mineral concentrate is digested in hydrochloric acid and the resulting REE laden liquor is passed through a sequence of solvent extraction with several mixer-settler steps. Final products of this element-selective extraction processes are either separated REO or other products following customer requirements.

Online Monitoring in Rare Earth Minerals Processing

The TOPAZ Rare Earth fulfils the requirements of the REE mining industry with the measurements of three key compounds:

Rare earths analyser

The online analysis of REE in condensate water, cooling tower and discharge water enables early leak detection along the mining process. Contaminated cooling water and condensate must be diverted and treated in WTP prior to be discharged. The TOPAZ Rare Earth from SERES Environment is specifically designed for to meet the REE industries in terms of environmental compliance and Process control.

Ammonium Bicarbonate analyser

Ammonium bicarbonate is used to precipitate the solution of cerium 4, the title of this solution, principally made from NH4 and CO2, determines the quality of the precipitate.  Accurate and fast monitoring of Ammonium Bicarbonate enables automated plant operations and optimal dosing.

Cerium analyser

Measurement of cerium 3 in cerium 4 for quality control and product categorisation depending on the specifications of the finished product.

ENVIRONMENTAL MONITORING

NOx Emissions Testing

The emission of pollutants resulting from a multitude of activities (industry, transport, …) alters the atmospheric composition and degrade air quality. Control of gaseous pollutant emissions in the atmosphere has become a major challenge for the protection of human health and the environment. To avoid these risks, the regulation has established discharge limits thresholds for certain pollutants and requires periodic inspections whose frequency depends on the type of activity (from 3 months to 3 years). Accredited stack testing companies and/or Site Environmental Managers are responsible for conducting short to medium term environmental compliance monitoring tasks in a wide range of industries and processes such as power plants and large manufacturing facilities including paper mill, foundry, waste recycling facilities,  refineries…

Flammable and toxic Offgas

Recent incidents have occurred in several open cut coal mines where flammable and toxic gases (NOx, SOx, CH4, CO, CO2 and H2S) have been found in areas where normal mining activities are being undertaken. Flammable and toxic gases have been found emitting from blast holes, post blast areas and strata, including spoil dumps and accumulating in the bottom of pits during temperature inversion events. Ignitions of methane have occurred during blasting operations and evidence of spontaneous combustion has been identified with the accompanying noxious gases. Methane gas has also been detected in product coal recovery tunnels, including in the cavity surrounding the coal chutes.

Hazards are evident when personnel and equipment operate in close proximity to these sources of flammable and toxic gases. Mine workers undertaking duties in and around the areas nominated should be made aware of the potential risks, their measurement and controls.

The following information may be useful in alerting mine workers in the characteristics of some the more commonly occurring gases found in open cut mines and their current recognised exposure standards.

With reference to the Coal Mining Safety and Health Regulation 2001 s142 Flammable or toxic gas, it is recommended that all open cut coal mine operators regularly review the mine Safety and Health Management System specifically related to the management of toxic and/or flammable gases on the mine site.

More specifically this review should focus on the effective implementation of the Standard Operating Procedure required under the Coal Mining Safety and Health Regulation 2001 s142.
