Pyrite is often symbiotic with copper, lead, zinc, molybdenum and other sulfide deposits and contains gold, cobalt, molybdenum and rare element selenium, etc., which can be recycled. Pyrite ores can be divided into pyrite ore, pyrrhotite ore, coal-based pyrite ore and multi-metal associated pyrite ore.
A、Single pyrite: generally relying on flotation, supported by gravity separation. The flotation adopts one-coarse-two-fine process to meet the production requirements.
B、Coal-based pyrite: This type of pyrite is generally produced with coal and recovered by screening and washing processes.
C、Lead-zinc ore associated with pyrite: the flotation is usually preferred and the minerals are in a sequence of lead, zinc and sulphur.
