Number mass balance counting method in mineral separation industry

Abstract

The invention relates to a number mass balance counting method in the mineral separation industry. The number mass balance counting method comprises the steps that firstly, a mass balance equation is listed according to the fact that the actual total mineral separation industry procedure input mass is equal to the total output mass; secondly, the priori knowledge serves as a constraint condition, and the mass balance equation is converted into a non-linear optimization question; thirdly, the non-linear optimization equation in the second step is solved, the obtained measurable value serves as a measurable modification value seen in the specification, the obtained solved value serves as a calculation value of the solved value seen in the specification, and the number mass balance question is solved. According to the number mass balance counting method in the mineral separation industry, the priori knowledge is fully utilized, the pure mass balance equation is converted into the non-linear optimization question based on the priori knowledge to be solved, very large tolerance is provided for the error of field measuring, the unreasonable measuring value can be automatically modified even when large errors exist in measuring, the reasonable and credible results can be reckoned, and the number mass balance counting method can be widely applied to the field of the mineral separation industry.

Description

technical field [0001] The invention relates to a method for calculating the number and mass balance in the field of mineral processing industry, in particular to a method for calculating the number and mass balance of the mineral processing industry. Background technique [0002] The beneficiation industry is the industrial process of screening the target metal components from the raw ore. The raw ore is crushed, grinded and flotation to obtain the final product. Any concentrator hopes to improve the performance of each process, thereby increasing the quality and yield of products. Obviously, it is necessary to have a detailed understanding of the production conditions on site in order to find ways to improve performance. If you don't know the production conditions on site, even the best engineer can't do anything. Therefore, data that can reflect on-site production conditions, such as pulp flow, water flow, metal yield, metal grade, etc., are of great significance to the ...
