Abstract

The invention relates to a method for separating and extracting feldspar ore with complex impurity components, which comprises the following steps of: 1) performing ball milling on the feldspar ore with complex impurity components through a ball mill; 2) performing classification and de-sliming on the milled feldspar ore by using an improved hydraulic classifier; 3) performing low-intensity magnetic separation on the classified feldspar ore through a low-intensity magnetic separator to obtain high-intensity magnetic substances and rough feldspar concentrate for high-intensity magnetic separation; 4) performing high-intensity magnetic separation on the rough feldspar concentrate obtained by the low-intensity magnetic separation through a high-intensity magnetic separator to obtain low-intensity magnetic substances and rough feldspar concentrate for flotation; and 5) performing size mixing and segmentation on the rough feldspar concentrate obtained by the high-intensity magnetic separation, adding a flotation agent, and performing reverse flotation, impurity removal and dehydration through a flotation machine to remove impurities and obtain fine feldspar and quartz mixed powder and flotation water.

Description

technical field

[0001] The invention relates to a method for separating and extracting feldspar ore, in particular to a method for separating and extracting feldspar ore with complex impurity components, and belongs to the fields of metallurgy and chemical industry. Background technique

[0002] According to different types of feldspar deposits and ore properties, different beneficiation methods need to be adopted. With the different deposits of feldspar, the ore properties and associated impurities may also be different. At present, the following mineral processing principles are generally adopted in domestic and foreign dressing plants: (1) High-quality feldspar produced from pegmatite: hand selection→ Crushing → ore grinding or water milling → classification; (2) Feldspar in weathered granite: crushing → ore grinding → classification → flotation; (3) Feldspar in fine crystal rock, generally containing mica, sometimes iron: crushing →Grinding→Sieving→Magnetic separation; ...
