Abstract

The invention discloses a composite force field sorting machine for magnetite sorting and a sorting method thereof. The sorting machine comprises a housing, wherein the housing is of a hollow verticalcolumn type cylindrical structure; a guide plate, a dispersing cylinder and a sorting cylinder are sequentially arranged in the housing from top to bottom; the axes of the dispersing cylinder, the sorting cylinder and the housing are on the same line; and a hollow coil capable of generating a magnetic field is arranged outside the housing. By using the device and the method provided by the invention, all that is needed is to adjust the feeding amount, the amount of flushing water, the height of the sorting cylinder, the magnetic field strength and the magnetic field position of the sorting machine according to the sorting process requirements, the adjustment and control of a particle distribution rule can be realized, thereby realizing sorting optimization. The composite force field sorting machine provided by the invention integrates the advantages of multiple sorting methods such as re-election, flotation and magnetic separation, not only can improve the concentrate grade of magnetite, but also ensure the recovery rate of magnetite; and the reverse flotation process of magnetite is effectively shortened, and thus the composite force field sorting machine is suitable for the process of reverse flotation iron increase and silicon reduction of magnetite.

Description

technical field [0001] The present invention relates to a compound force field sorting machine and its sorting method for magnetite sorting, in particular to a sorting machine integrating gravity, magnetic and floating multi-force fields and its sorting method. It belongs to the field of mineral processing. Background technique [0002] my country's iron ore resources are widely distributed, with complex ore types and poor resource quality. With the continuous development of iron ore resources, the proportion of low-quality iron resources such as fine-grained ore and symbiotic ore is increasing. Conventional and single beneficiation techniques are usually difficult to obtain ideal technical and economic indicators. The equipment still lags behind the foreign level, and the development and improvement of new efficient mineral processing equipment is still the top priority in the development of mineral processing technology. [0003] At present, the mineral processing equipm...
