Identification method of properties of manganese ore and manganese smelting slag

Abstract

The invention relates to a method for identifying the attributes of manganese ore and manganese smelting slag. The method uses X-ray diffraction spectroscopy and infrared spectroscopy to identify the attributes of manganese ore and manganese smelting slag. Search for characteristic peaks of manganese oxide, bistrosite, rhodochrosite, etc., and analyze and compare with characteristic peaks such as iron silicate in manganese smelting slag to identify the properties of manganese ore. At the same time, it can be proved by infrared spectrum characteristics. ~400cm ‑1 There are two strong absorption bands in the range, and they are separately or simultaneously at 1420cm ‑1 There is a characteristic absorption peak at , and the manganese smelting slag is at 960cm ‑1 The nearby wide and strong absorption peaks can confirm and identify the properties of manganese ore at the same time. This identification method provides technical support for inspection and quarantine and customs, and provides scientific identification reports for traders to ensure border security and avoid environmental pollution and trade fraud.

Description

technical field [0001] The invention relates to a method for identifying manganese ore, in particular to a method for identifying the properties of manganese ore and manganese smelting slag. [0002] This method is applicable to the identification of manganese ore and manganese smelting slag properties by the inspection and quarantine system, customs, scientific research units, colleges and universities, testing centers and manufacturers. Background technique [0003] Manganese ore refers to manganese-containing minerals formed under natural conditions, and is mainly used for the extraction of manganese. In modern industry, manganese and its compounds are used in various fields of the national economy, among which the iron and steel industry is the most important field, and the amount of manganese used accounts for 90% to 95%. It is mainly used as a deoxidizer and desulfurization in the process of ironmaking and steelmaking agent, and used to make alloys. During the "Eleve...

Problems solved by technology

[0004] Under the conditions of marketization, disorderly competition has been triggered, and the pursuit of the maximum profit has caused illegal traders at home and abroad to shoddy good ones, pass fake ones as real ones, and mix smelting waste slag that is prohibited from importing in my country, which has seriously affected my country's The trade environment has harmed the interests of importers, and at the same time caused serious damage to our country's ecological environment

Manganese slag is mainly composed of oxides of silicon and calcium. The manganese content is low, the smelting value is very low, and it contains a large amount of toxic and harmful heavy metals, such as lead, zinc, arsenic, and copper. The above-mentioned harmful heavy metals will pollute surface water, groundwater and soil. Serious damage to the ecological environment

[0005] However, because manganese smelting slag has similar element composition and content with some manganese ores, it is sometimes impossible to accurately distinguish them only from the level of element content.

At present, there is no effective identification method for manganese ore and manganese smelting slag in my country, which makes the investigation and handling by customs and other departments quite troublesome. Therefore, it is urgent to establish an effective identification method for manganese ore and smelting slag, so as to better safeguard the national economic interests and protect the national ecological environment.
