Metal mineral phase analysis
Phase analysis based on a variety of minerals in the ore mainly in a variety of different solvent solubility and dissolution rate, in all kinds of solvents under different conditions, different concentration of ore sample processing analysis, make all kinds of minerals in the ore separation, some elements of the sample can be measured is what minerals exist and how much content.
Spectral analysis and chemical analysis can only find out the elements contained in the ore types and content, also can't point out various elements is a what kind of compound exist, only through physical phase analysis and rock ore appraisal and so on work, to know what certain elements in the ore in mineral.
According to the existing data, physical phase analysis can be performed to the following elements:
Copper, lead, zinc, manganese, iron, tungsten, tin, antimony, cobalt, bismuth, nickel, titanium, aluminum, arsenic, mercury, silicon, sulfur and phosphorus, molybdenum, indium, germanium, and beryllium, uranium and cadmium, etc.
Various elements which need to analyze several phase, can find the relevant information, don't go into here.
To depend on the microscopic analysis as the main method of rock ore appraisal and phase analysis operation faster, accurate quantitative, but can't will distinguish all minerals, more important is unable to determine the spatial distribution of these minerals in the mineral and disseminated, Mosaic relations, therefore in the mineral composition is an auxiliary method in research work, can't replace rock ore appraisal.
For processing staff, does not need to command phase analysis of the technology, mainly to understand the phase analysis which elements can do? Each of these elements need to analyze several phase? That each element is what kind of mineral? All kinds of mineral optional sex? Constitute a, for example, the spectrum analysis of tungsten element is roughly content, chemical analysis of tungsten oxide content, but what exactly are tungsten oxide is scheelite and wolframite, or both, it must be through the phase analysis and rock ore appraisal and so on comprehensive analysis to determine: such as scheelite, according to its disseminated extent by gravity separation or flotation method; Such as wolframite is generally only use gravity separation method; If both have available heavy - float joint method processing. With these basic concepts, to phase analysis put forward reasonable requirements, to correct analysis and the plan of using phase analysis data. If now can't do, don't send sample phase analysis.
Due to the complexity of ore properties, some elements phase analysis method is not mature enough or in continue to research and development, must therefore be comprehensive analysis of phase analysis, rock ore appraisal and other data analysis methods, to draw the right conclusions.
