Document Type and Number:
WIPO Patent Application WO/2023/019776
Kind Code:
A1
Abstract:
The present invention relates to the technical field of ore dressing, and provides a pre-selecting and waste-discarding method for non-ferrous metal ores. According to the present invention, the method comprises: firstly, carrying out crushing and primary screening and classification to obtain a first coarse ore, a first fine ore and a first qualified ore; subjecting the first coarse ore to pre-selecting and waste discarding by means of intelligent ore sorting to remove gangue tailings therein; crushing a remaining first rough concentrate and then subjecting same to secondary screening and classification to obtain a second fine ore and a second qualified ore; and finally, subjecting the first fine ore and the second fine ore to pre-selecting and waste discarding by means of heavy-medium separation to further remove gangue tailings therein, wherein the concentrate obtained by means of the heavy-medium separation is a qualified ore. In addition, the intelligent ore sorting or the heavy-medium separation may be further used alone for pre-selecting and waste-discarding in the present invention, making process steps simpler. The method provided in the present invention has a high automation degree, high ore dressing accuracy, a high non-ferrous metal ore recovery rate, a high waste discarding rate and no limitation on the types of ores, and is widely applicable.
