Why we should conduct process mineralogy study?

Beneficiation is a very important process for producing qualified concentrate from low grade raw ore for smelting process. Nowadays, the high grade raw ore is getting less, to get enough raw materials, many of low grade ore has to be utilized. And beneficiation becomes essential. 

To evaluate the beneficiability of the ore and identify the most suitable beneficiation process, a process mineralogy process study can be very useful. Metalcess can provide Process Mineralogy Study service for clients with a nice budget. Our mineralogy study is conducted in the most advanced and authorized lab in China.

Process Mineralogy Study method

The process mineralogy study plays a crucible guiding role in the beneficiation of ores. By spectral analysis and quantitative chemical analysis, the types and contents of mineral elements contained in the ores can be quickly and comprehensively identified, which is important for a precise ore quality evaluation and making co-responding multi-element comprehensive recovery beneficiation process. The occurrence state of useful and harmful elements in ores is the basis for beneficiation test plans. The structural and textural characteristics of ores, the shapes of main mineral particles, the grain size, the embedding relationship and characteristics, etc., are of great significance to the ores beneficiability, directly determining the difficulty of liberation of useful minerals during crushing and grinding and the characteristics of associated minerals. 

The raw ore block samples are mainly used to study the primary state of the ores embedding characteristics. The crushed raw ore powder samples are used to study the distribution law of valuable elements in the ore and the beneficiation properties.Besides the combination of macroscopic observation and microscopic research, the samples are subjected to fluorescence spectrum analysis, chemical multi-element analysis, chemical phase analysis, etc. Then, more than 30 samples are prepared for grinding and polishing. After the pretreatment of the prepared samples, a series of studies are conducted by using high-precision optical microscopes, X-ray diffraction analyzers, scanning electron microscopes and energy spectrometers, and mineral automatic analysis systems,which provides a accurate and detailed mineralogical basis for the proper industrial utilization of the ores.
