AXT Pty Ltd has recently added an automated sample loading accessory for the TESCAN Integrated Minerals Analyzer or TIMA system. AXT Pty Ltd represents TESCAN in Australia and New Zealand.
The TIMA is a scanning electron microscope tool, designed specifically for the rapid analysis of rocks, ores, concentrates, tailings, leach residues or smelter products and various geological samples.
The newly developed automated loading system allows robust, continuous and unattended sample loading with the robotic system able to accommodate up to 100 epoxy blocks 25mm or 30mm in diameter and facilitating 24/7 operation with minimal user input and effort.
The TIMA system combines Backscatter Electron imaging (BSE), cathodoluminescence (CL) and Energy Dispersive X-Ray Analysis (EDX) to perform functions such as minerals analysis and identification, minerals concentration, particle size distribution and liberation/locking parameters in an automated fashion. It is also able to perform bright particle/phase searches for PGM, heavy metals and gold-silver ores.
The seemingly complicated functions are easy to perform with TESCAN engineers having designed the system for simple operation.
AXT’s Managing Director, Richard Trett comments that a large capacity autoloader is a game changer for large users with extended unattended operation improving efficiency and allowing for the mineralogist to focus on analysis rather than sample management. Built-in traceability via barcodes and visual identification also allow for ease of repeat analysis and refinement on a large stock of samples.
The TIMA minerals analyser with automated loading system is ideally suited to continuous operation and can greatly assist operations of mining and minerals exploration companies in monitoring ores and analysing drill cores.
AXT will have the TIMA on display at the upcoming ACMM23/ICONN2014 conference, where both AXT and TESCAN are gold sponsors. The TIMA will be available for personalised demonstration by appointment throughout the event.
