Acid leaching PTMS magnetic separator has a good effect on the removal of non-metallic impurities in quartz
high gradient magnetic separation
Pickling. Also known as acid soaking, can be cold soaking or warm soaking. The iron reacts with the acid to remove iron oxide or other iron from quartzite, albite or potassium. Acid leaching PTMS magnetic separator can not only remove iron minerals from quartz sand, but also has a good effect on the removal of non-metallic impurities in quartz. However, the use of sulfuric, hydrochloric, nitric and hydrofluoric acids is costly and has a high environmental impact.
PTMS magnetic separator
Oxalic acid reacts with Fe3+ on the surface of ore particles to form a complex that dissolves in water, so as to achieve the purpose of iron removal. However, in this case, the dissolution mechanism of iron is different from that of inorganic acid to iron minerals. The main advantage of using oxalic acid PTMS magnetic separator for iron removal is that a soluble complex is formed during leaching, which can be decomposed by both microorganisms and sunlight.
what is magnetic separation in Feldspar ?
Pegmatite generally selective mining or hand selection, dry processing. Raw ore → Coarse crushing → Fine crushing → grinding → PTMS magnetic separator/Electrostatic Separation → classification → Packaging → Product. Color separation series is through the photoelectric detection technology will be quartz ore, potassium alspar yellow particles out, in order to achieve the purpose of reducing iron content.
