Abstract

The embodiment of the invention provides a flotation foam grade calculation method and device, electronic equipment and a medium, and belongs to the technical field of technological process data collaborative calculation. In order to solve the problems that at present, a specific flotation foam grade value cannot be given, and intelligent control over the flotation process cannot be achieved, the following scheme is provided: obtaining foam grade related variables of a flotation foam standard sample; constructing a flotation foam grade empirical model according to the foam grade characterization expression and the field production empirical data; according to the foam grade representation expression and the field production experience data, a flotation foam grade network model is constructed based on a neural network; fusing the flotation froth grade empirical model and the flotation froth grade network model to obtain a final flotation froth grade prediction model; and calculating the flotation froth grade through the final flotation froth grade prediction model. In this way, online prediction of the flotation foam grade is achieved through the final flotation foam grade prediction model, and intelligent control over the flotation process is achieved.

Description

technical field [0001] The present application relates to the technical field of collaborative calculation of process data, and in particular, to a method, device, electronic device and medium for calculating the grade of flotation foam. Background technique [0002] Grade refers to the mass percentage of useful elements in pulp, and is the most important flotation index in the flotation process. The two main products of the flotation process are concentrate and tailings. The production requires concentrates with high grade and output, and the lower the content of useful minerals in tailings, the better. However, due to the influence of ore properties and beneficiation technology, some useful minerals in tailings cannot be recovered, so real-time detection of flotation concentrate and tailings grade is very important. [0003] For a long time, the flotation site has mainly relied on the operator to observe the visual characteristics such as the color and size of the froth o...
