Real-time analysis of ore

Real-time analysis of ore enables the cost of beneficiation to be reduced, by allowing processes to be adjusted to take account of changing compositions. Doing this can save hundreds of thousands of dollars per month by avoiding unnecessary processing of low-grade or non-upgradable ore and allows optimal blends to be produced for downstream processing. For direct shipping ore (DSO), real-time monitoring also avoids penalties by ensuring consistent quality.

Malvern Panalytical provides equipment for real-time elemental analysis, mineralogical analysis and moisture monitoring, which together can provide a full picture of ore quality. In addition, we also supply instruments for real-time particle size monitoring and wastewater monitoring.

Real-time process control of elemental composition

Real-time process control of elemental composition involves grading of ore early in the process. This allows low-quality feed to be excluded from downstream beneficiation processes, improving efficiency and driving down costs – whatever the type of ore or the ultimate commodity.

Malvern Panalytical offers equipment using Pulsed Fast Thermal Neutron Activation (PFTNA) technology to provide elemental analysis directly on the conveyor belt. Used in conjunction with a mineral composition analyser, plant managers can obtain a complete picture of ore quality.

Real-time monitoring of mineral content

Real-time monitoring of mineral content on the conveyor allows significant cost savings to be made, by:

• Reducing the amount of acid used in beneficiation processes
• Improving heap-leaching percolation rates by accurately determining total clay content
• Providing information on gangue minerals, which is valuable when optimizing flotation processes.

Malvern Panalytical provides near-infrared (NIR) equipment that allows full analysis of mineral composition. Used in conjunction with an elemental composition analyser, a full understanding of ore quality can be obtained by the plant manager.
