Abstract

The invention relates to a method for distinguishing iron ore with sintered ore and return ore. The X-ray diffraction spectroscopy and the scanning electron microscopy are adopted in the method, wherein the analysis comparison is performed to the spectrum peak of calcium magnesium iron silicate through X-ray diffraction spectrum, whether the remarkable characteristics of the sintered ore or the return ore exist or not is judged, and the attribute of the iron ore, the sintered ore and the return ore is distinguished gradually. The distinguishing method achieves the purpose of preventing the name of commodities in import cargoes from being changed from source, provides technical support for quarantines and customs, provides scientific survey report for traders, ensures border security and avoids environmental pollution. The distinguishing flow is provided and established for the first time, the working procedure of distinguishing is standardized, and the method is instructive in distinguishing all the imported waste raw materials.

Description

technical field

[0001] The invention relates to an inspection method of iron ore, in particular to an identification method for distinguishing iron ore from sintered ore and returned ore. This method is suitable for the inspection and quarantine system, customs, scientific research units, colleges and universities, testing centers and manufacturers to identify iron ore, sintered ore and returned ore. Background technique

[0002] Iron ore refers to iron-containing minerals, which can be used for refining elemental pig iron, steelmaking and many other purposes. It is the most basic and most demanded smelting raw material in the iron and steel industry.

[0003] Since the reform and opening up, China's economy has developed rapidly, and the demand for iron and steel has increased year by year. With the rapid development of the iron and steel industry, my country's iron ore output is far from meeting the needs of the iron and steel industry. Imported iron ore has become one of...
