Is Granite Magnetic? (Answered)
It is mostly made up of quartz and feldspar, which are non-magnetic. However, in some cases, granite can include ferromagnetic metals like iron and be slightly magnetic. Quartz (silica) and feldspar (aluminum) are both diamagnetic. The …
Magnetic Separation
Based on the level of magnetism, minerals can be divided into strongly magnetic minerals (such as magnetite), weakly magnetic minerals (such as chalcopyrite), and nonmagnetic minerals (such as quartz, feldspar, etc.). The magnetic force of magnetic mineral particles in a magnetic field is related to the magnetism of the mineral itself.
