Process Description

Introduction: According to different feldspar mineral types and ore properties, Shunzhi customizes a series of feldspar processing technology, including magnetic separation, flotation, gravity separation and combined technology. So as to achieve the removal of mica mineral impurities, etc., to obtain potassium and sodium feldspar concentrate, aiming to obtain high-grade feldspar concentrate.

Application: Shunzhi feldspar processing technology is suitable for potash feldspar, sodium feldspar and nepheline syenite.

  • Crushing & Grinding

  • Large particle size of feldspar ore firstly should be crushed by jaw crusher to qualified particle size, thus to guarantee the grinding quality and protect ball mill.Ball mill is applied into the second stage - grinding, Shunzhi has wet grate ball mill and wet grate overflow ball mill which can perfectly grind feldspar ore into qualified particle size.

  • Flotation Separation

  • With experience in Feldspar flotation separation, flotation cell is the main mining machines in this part, the slurry dealt with agential through milling and inflating can make certain particles of it selectively attaches to the bubbles to achieve mineral separation.Besides flotation machines, other mining machines also will be used in the stages, if you want to know more, just click the online service.

  • Desliming

  • Qualified grinding materials are fed into desliming bucket for desliming operation.

  • Magnetic separation

  • After desliming, the ore enters the two-stage magnetic separation operation of low intensity magnetic + high intensity magnetic to remove magnetic substances in the ore.

Processing Flow

  • Mining: Feldspar ore is mostly mined by open-pit method, and raw ore is obtained through blasting and excavation.

  • Crushing and Screening: After crushing feldspar raw ore by jaw crushers, classify ore of different particle sizes with vibrating screens and remove large waste rock.

  • Ore Washing: Remove slime and clay impurities from feldspar ore with sand washers to improve feldspar purity.

  • Magnetic Separation: Feldspar ore usually contains iron impurities, remove ferromagnetic minerals by high-gradient magnetic separators to reduce iron content.

  • Flotation (Optional): If feldspar is associated with quartz and mica, adopt flotation to separate them; cationic collectors are used to remove mica, and fluoride regulators are used to separate quartz.

  • Thickening and Dewatering: Concentrate and dewater feldspar concentrate to obtain feldspar concentrate filter cake.

  • Drying and Classification: Dry the filter cake and screen feldspar finished products of different particle sizes through classification equipment for industrial fields such as ceramics and glass.
