Embodiment Construction

[0055] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0056] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0057] Unless otherwise def...

Abstract

The invention discloses an intelligent magnetic iron ore separating method and device. The method comprises the following steps that the lowest grade and the particle size range of to-be-separated magnetic iron ore are confirmed; the magnetic field intensity and position of a magnetic source capable of making the lowest-grade magnetic iron ore in the to-be-separated magnetic iron ore generate a detectable signal are determined; signal acquisition is conducted on the ore randomly selected from the to-be-separated magnetite ore to obtain signal acquisition data, and the signal acquisition data are preprocessed to obtain preprocessed data; dimension transformation is conducted on the preprocessed data to generate corresponding ore samples, and the ore samples are divided into a training set and a test set; the training set is trained, and a model is tested through the test set to judge whether the test result meets the current mineral separation standard or not; and if yes, the deep learning model is trained successfully, and the deep learning model and a data acquisition system are embedded into an automatic separation device to conduct magnetic iron ore separation. The selected grade of the to-be-separated magnetite ore is expanded, and the ore utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of ore intelligent separation, in particular to a magnetite ore intelligent separation method and equipment. Background technique [0002] my country is rich in iron ore resources, but there are few rich ore, lean ore and refractory ore. It is necessary to continuously import foreign iron ore to ensure domestic iron ore production, resulting in excessive dependence on foreign iron ore and affecting the development of my country's mineral processing enterprises. For this reason, domestic enterprises improve the comprehensive utilization rate of iron ore through pre-selection and discarding, thereby reducing the waste of mineral resources and reducing the cost of mineral processing. [0003] The pre-selection and discarding method specifically uses the difference in magnetic force of different grades of magnetite ore in the same magnetic field for separation, which improves the utilization rate of the ore to a...
