METSO A413146 Timer & Memory Management Module

The demand for accurate and well-maintained elemental analyzers continues to rise

as ore grades decline in the mining industry. In particular, the extraction of precious

metals such as gold presents a significant challenge due to their low concentration in

tailings. To address this issue, the Ada Tepe mine, owned by Dundee Precious Metals,

located in southeastern Bulgaria, sought to improve its gold recovery and process control,

all whilst reducing any losses to tailings.

As the first greenfield mine in the country in four decades – and boasting one of the highest

 open pit gold grades in the world – Ada Tepe required a cutting-edge solution capable of

real-time and reliable elemental analysis measurements.

Specifically designed for on-stream analysis, the Courier® 6G SL analyzer revolutionizes the

direct measurement of gold, platinum, and other valuable metal concentrations in ore feed,

concentrate, and tailings streams. By delivering fast and accurate elemental analysis data,

the analyzer enables mining operations to have more efficient process control, thus enhancing

process stability and maximizing recovery rates. The typical measurement time for gold in feed

is one to five minutes, for concentrate streams 30 to 60 seconds and in tailings five to 20 minutes

due to lower elemental concentrations. Total cycle time for feed, concentrate and tailings streams

can be as low as 30 minutes, which enables operators to react much faster to changes in the process.

Courier legacy upgrade is a low-risk pathforward to the latest industry-leading

analyzer technology. Courier analyzer systems offer unrivaled sensitivity and

the shortest cycle times for process management, monitoring, and control of all

types of mineral processing plants.

The new generation XRF Courier analyzersare based on the same industry-leading

Wavelength Dispersive X-ray Fluorescence (WDXRF) measurement principles as

their predecessors but enable higher analysis accuracy with reduced cycle

times. In addition to the WD measurement channels, the new Courier analyzers can

also be equipped with Energy Dispersive X-ray Fluorescence (EDXRF) measurement

channels to measure additional elements.

Increased safety, performance and availability

Upgrading results in reduced maintenance and guaranteed spare part availability with

additional features such as digital tools for enhanced diagnostics and easier fault

tracking. The user-friendly operator interface with enhanced connectivity to other systems

provides an easier way to maximize process performance.

The latest software assures better usability, improved remote support and enhanced

network security. Service agreements can be included to ensure peace of mind knowing

that the analyzer will operate with maximum availability and accuracy.
