| titleOfInvention | Method for preparing low-iron quartz sand from granite feldspar ore |
| abstract | The invention discloses a method for preparing low-iron quartz sand from granite feldspar ore, which comprises the following steps of: (1) preparing the granite feldspar crude ore into quartz sand with the grain size fraction of 0.1-0.7 mm accounting for 95%; (2) reduction of Fe in quartz sand by two-stage magnetic separation process 2 O 3 Content, obtaining intermediate product magnetic separation concentrate; (3) performing coarse (floating) separation on the magnetic separation concentrate to obtain coarse concentrate and coarse tailings; (4) carrying out primary fine selection on the rough concentrate to obtain feldspar concentrate and middling 2; (5) and (4) carrying out once scavenging on the coarse tailings to obtain low-iron quartz sand and middlings 1. (6) Middling 1 and middling 2 are combined and returned to rough concentration. After the method is used for sorting, feldspar concentrates meeting the first-level product indexes in the aspects of ceramic glaze, ceramic white blank, plate glass and the like can be obtained, and low-iron quartz sand meeting the requirements of ultra-white glass and photovoltaic glass raw materials can be recovered, so that the comprehensive utilization of resources is realized. |
