Instrument for identifying metal content of mineral qualitatively and automatically

Abstract

The invention relates to an instrument for identifying the metal content of mineral qualitatively and automatically. The instrument consists of an X-ray tube (1), a high-voltage power supply (2), an integrated semiconductor detector (3) and an X-ray processor (4). The original-level X rays generated by the X-ray tube (1) and the high-voltage power supply (2) are the excitation source of the instrument for identifying the metal content of the mineral qualitatively and automatically. The integrated semiconductor detector (3) adopts an integrated structure formed by an X-ray detector, an amplifier (31), a digital pulse processor (32), a power supply and interface (33) and a +5-volt power supply (34). An X-ray spectroscopy principle is utilized, the mineral passing through an original-level X-ray irradiation area at the front end of the X-ray tube (1) is automatically identified by the X-ray processor (4), whether the mineral contains useful metal or not is determined, and an accurate processing signal is provided for an execution mechanism to decide to maintain or remove the mineral. The instrument has the advantages of compact and simple structure, capability of mounting a plurality of automatic identifying instruments, high measuring accuracy and the like, has high detection level, high excitation capability and excellent measuring precision, and avoids nuclear pollution.

Description

technical field [0001] The invention relates to an ore metal content detection technology, in particular to an ore metal content qualitative automatic identification instrument. Background technique [0002] In the process of mineral processing, the on-line analysis technology of ore metal content has a wide application space, and the use of X-ray fluorescence analyzer to analyze ore metal content has many significances. [0003] Ore metal content detection technology is an ore metal content analysis technology that uses primary X-ray photons or other microscopic ions to excite atoms in the mineral substance to be tested to generate fluorescence (characteristic X-rays) for mineral composition analysis. This technology mainly includes excitation, dispersion, detection, recording and data processing units. Determine whether the ore contains useful metals, provide accurate processing signals for the executive agency, decide whether the ore will go or not, and waste rocks will ...
