矿物砂：具有重要重视的小粒度的创新分析
Rare and valuable, heavy mineral sands provide resources that are critical to the modern economy. Heavy mineral sands are paleo dune, beach, or river deposits enriched in high density minerals such as ilmenite, zircon, leucoxene, monazite and rutile. Less commonly garnet, magnetite, sapphire, diamond and staurolite are also mined from heavy mineral sand deposits. The natural hydrodynamic processes of ancient environments sorted sands by density,which can also be seen on modern beaches as dark sand layers. Heavy mineral sands are used as raw feedstocks in industrial processes and as products themselves. Zircon is used for control rods in nuclear reactors. Rutile is the primary source of titanium for white paints. Some sand is also used as proppant for hydraulic fracturing in oil and gas wells and as a source of high-purity silicon. The possibility of extracting rare earth elements from mineral sands is being actively explored.

元素测定
用X射线荧光进行元素测定
X-ray fluorescence spectroscopy (XRF) provides one of the key methods for elemental assay of mineral sands for quality assessment and grade control. Elemental analysis of heavy mineral sands is a critical step in certifying prospectivity of discoveries and confirming grade in product streams. Bruker’s elemental analyzers can be calibrated with matrix-matched calibrations to specific deposits and customized to meet the need of any analytical workflow. From portable analyzers at the excavation site to central laboratory analysis, Bruker is your partner for analytical success.

解放和粉碎
通过计算解放度来节约能源
这comminution process is one of the most energy intensive phases in the mining value chain. Mineral liberation analysis is used to optimize this process by calculating the degree of liberation of a sample. Liberation is the degree of freedom of a target mineral phase from its surrounding matrix. Automated mineralogy combines Scanning Electron Microscopy (SEM) with energy dispersive spectroscopy (EDS) to quickly and accurately quantify mineral texture in samples and calculate the degree of locking or liberation for a target mineral. Bruker AMICS automated mineralogy platform is leading the industry with recent advances in the price and usability of both the software and application on compact or desktop SEMs; Automated mineralogy is now accessible to any sized operation.
快速的纹理分析
一种用于分析矿泉水的新型自动化学和矿物测绘方法
Grades for economic deposits of heavy mineral sands are low, with typical values of target mineral grains between 1% and 3%. This complicates exploration, as the low-grade peripheries of deposits may be below the detection limit of XRF or XRD. The uniqueness of each deposit requires specific approaches to processing, commonly requiring complex arrays of density separation equipment. Detailed optical or chemical characterization of sediment texture becomes an important factor in exploration, processing plant design, and ongoing grade control and deposit management. Micro-XRF is emerging as new method for quick-look mineral identification and textural assessment. Some key features of this method:
