Embodiment 1
[0021] A beneficiation process for producing high-quality iron concentrate from Mongolian iron ore mainly includes the following parts:
[0022] 1. The Mongolian iron ore is firstly subjected to one-stage grinding (mill model Φ3.2×4.5m), and the first-stage grinding product enters the classifier for a classification operation to obtain a graded sand settling product and a graded overflow product;
[0023] 2. The primary graded grit products obtained by the above steps are subjected to secondary grinding (mill model Φ3.6×4.0m), and the secondary grinding products are returned to the primary classification for inspection and classification; primary grading overflow products enter the cyclone The secondary classification operation is carried out by the device, and the secondary classification grit product and the secondary classification overflow product are obtained;
[0024] 3. The secondary graded grit settling product obtained by the above steps is subjected to three-stage gr...
