Separation technology of potassium alspar PTMS magnetic separator
Due to the iron minerals, biotite and tourmaline in potash feldspar have certain magnetic properties, so magnetic separation is an important separation process for feldspar. In general, these minerals have weak magnetic properties, so the separation can be carried out using high magnetic PTMS magnetic separator process and equipment.
Flotation process of potassium alspar PTMS magnetic separator
Flotation has a good effect on improving the quality of potassium albite, which can not only remove iron and titanium minerals in potassium albite, but also realize the separation of feldspar and quartz. For different impurities, the flotation agents used will be different.
1. In the separation of potash albite and mica, the reverse flotation process is often used, so as to reduce the loss of feldspar in mica flotation. Generally, the reverse flotation can be carried out under acidic or alkaline conditions, but most of the concentrator adopts amine cationic collector to carry out the reverse flotation under acidic conditions.
2. When separating potassium albite and quartz, acid flotation, neutral flotation and alkaline flotation can be used. PTMS magnetic separator can remove iron (FE2O3) inside.
Acidic flotation method: Under the action of pH=2-3, the use of anion and anion mixed collector gives priority to flotation of potash feldspar.
◆ Neutral flotation method: potassium feldspar is collected by amine cationic collector in natural neutral medium.
◆ Alkaline flotation method: quartz reverse flotation with alkylsulfonate collector under pH=11-12 with alkaline earth metal ions as activator.
