Abstract

The invention discloses an optical fiber Raman system and method for tungsten flotation concentrate grade online detection. The method is based on a Raman spectrum technology, a flotation cell foam layer Raman spectrum online measurement device in tungsten flotation is designed, and a Raman spectrum data online processing system of foam layer minerals is constructed, so that tungsten flotation foam layer Raman spectrum related characteristics acquired in real time are extracted, a concentrate grade online quantitative calculation model is constructed, and finally, a tungsten flotation concentrate grade result is acquired online. According to the designed optical fiber Raman system, the tungsten concentrate quantitative analysis model is established on the basis of Raman spectrum feature vectors under different tungsten concentrate grades, the tungsten concentrate grade value in a foam layer is obtained in real time in the flotation process, important production and assessment indexes in tungsten flotation can be monitored online, and important parameters are provided for tungsten flotation whole-process control.

Description

technical field [0001] The invention relates to the technical field of on-line spectrum detection, in particular to an optical fiber Raman system and method for on-line detection of tungsten flotation concentrate grade. Background technique [0002] Mineral flotation is the most widely used beneficiation method for raw tungsten ore. Mineralization and foaming are carried out through extremely complex physical and chemical reaction processes. The application of mineral flotation technology is to improve the grade of raw tungsten ore and meet the requirements of reduction smelting of tungsten ore. The concentrate grade in tungsten flotation is the content of useful substances in the beneficiation process, and is an important process index in tungsten flotation. Online real-time acquisition of tungsten flotation concentrate grade can guide the reasonable addition of reagents and the setting of working parameters in the flotation process, so that the flotation process is in the...
