Mineral separation is a process of crushing and grinding ores according to physical and chemical properties of different minerals in the ores, separating useful minerals from gangue minerals by methods such as a gravity separation method, a flotation method, a magnetic separation method, an electric separation method and the like, separating various symbiotic (associated) useful minerals from each other as much as possible, and removing or reducing harmful impurities to obtain raw materials required by smelting or other industries. The mineral separation can enrich useful components in the minerals, reduce the consumption of fuel and transportation in smelting or other processing processes, and enable low-grade minerals to be economically utilized. The data obtained from the mineral separation test is the main basis for the evaluation of the mineral deposit and the design of factory building.
The magnetic difference of the mineral particles is utilized to carry out sorting in the inhomogeneous magnetic field. Separating strong magnetic minerals (magnetite, pyrrhotite and the like) by using a low-intensity magnetic field magnetic separator; weakly magnetic minerals (hematite, siderite, ilmenite, wolframite and the like) are separated by a high-intensity magnetic separator. The low-intensity magnetic field magnetic separator is mainly an open-circuit magnetic system and mainly consists of permanent magnets, and the high-intensity magnetic field magnetic separator is a closed-circuit magnetic system and is a multipurpose electromagnetic magnetic system. The weak magnetic iron mineral can also be changed into a strong magnetic mineral through magnetization roasting, and then is selected by a weak magnetic field magnetic separator. The magnetic separator is constructed in a drum type, a belt type, a rotary ring type, a disc type, an induction roll type, etc. The magnetic pulley is used for pre-separating blocky ferromagnetic ores. The main development trend of magnetic separation is to solve the recovery problem of fine-grained weakly magnetic minerals.
There have been a plurality of copper sulphur ore dressing devices that are rich in pyrite on the existing market, but current device still has the space of improving, for example, current for collecting pyrite, adopt drum-type magnetic separation method usually, but drum-type device is selected separately inadequately, and discharge efficiency is not high, can't integrate crushing process in the sorting process.
