At the pre-stage of metal extraction, Metalcess provides mineralogy study, crystal texture and elemental analysis to identify the valuable minerals and its characteristics, facilitating the selection of extraction process and equipment.

The mineralogy study mainly involves Mineral Liberation Analyzer (MLA), an equipment consists of a set of FEI scanning electron microscope (SEM) and a set of EDAX energy disperse spectroscopy (EDS). The SEM scans the sample with a focused beam of electrons that interact with atoms in the sample and produces certain images readable by computer software. In combination of the image from SEM and energy dispersion signal from EDS, the MLA analyzes such information as mineral type, relative component and content, mineral liberation, etc. The analysis system is very efficient and it can perform measurement on 10,000 mineral particles within half hour. Specially, the sytem is good at searching for rare and precious metal such as gold, silver, platinum group metals, tantalum, niobium and radiative minerals. It provides reliable and trusty data for process design and optimization of ore beneficiation. 

X-Ray Diffraction (XRD) is the device for mineral texture analysis. The X-ray from XRD interact with crystal structure and diffract into specific direction, thus identifying the atomic structure of crystal. The test is non-destructive, reliable and highly efficient. 

Metalcess carries out inductive coupled plasma-atomic emission spectrometry (ICP-AES) test to identify the mineral elemental information to ensure high accuracy, stability and reliability.
