Potash feldspar ore dressing process

Crushing and screening stage

According to different block particle sizes of raw ore, xingaonai has formulated different crushing processes, from a simple one-stage crushing process to a three-stage crushing process. The block ore is coarsely crushed and then screened. The qualified ore in the crushing stage enters the grinding process. operation, the ore on the screen will be returned to fine crushing, ensuring the qualification of the particle size of the ore entering the next stage of operation.

Grinding and grading stage

The qualified products in the crushing stage enter the wet grid ball mill for grinding. The discharge from the ball mill enters the classification equipment for classification. The sand settled in the classification equipment returns to the ball mill for regrinding. The overflow of the classification equipment is the qualified product in the grinding stage.

Desliming stage

Send qualified grinding materials to the desliming bucket for desliming operations.

selection stage

Magnetic separation stage: The deslimed ore enters the two-stage magnetic separation operation of weak magnet + strong magnet to remove magnetic substances in the ore.
Flotation stage: In order to remove impurities such as iron, calcium and mica that may exist in the magnetic separation concentrate, separate excess quartz in the ore and improve the concentrate grade, the magnetic separation will The concentrate is flotated to remove impurities and purify. For impurity minerals, Xingaonai usually uses well-selective collectors to obtain high-grade feldspar fine powder.
