Wolframite is a weakly magnetic mineral which can be separated by magnetic separation. The magnetic separation process of Wolfram ore coarse concentrate: before separation, the materials are crushed to 3 mm by roller crusher, and then they are screened into three grades of 0.83 3 mm, 0.2 0.83 mm and 0 0.2 mm.
Magnetic separator is a general term for equipment that uses magnetic force to separate magnetic substances from non magnetic substances. They play a very important role in the beneficiation process. Most magnetic separators are used for ore selection, such as quartz sand, garnet, pyrite, hematite, limonite, siderite, etc.
As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4% Fe to 15% Fe and oxidized iron ore of only about 10% Fe to 20% Fe
