wolframite and casserite separation technique

Difficulty has been experienced in the separation of wolframite from cassiterite through a tendency of magnetic particles to adhere to the cassiterite thereby causing it to be drawn into the magnetic product when a strong field is used for separation this tendency may be overcome by treating the concentrate with sulphuric acid and drying before pasing it to the separator

Mar 26 2014 · Magnetic separation was first applied to the separation of wolframite from cassiterite The first magnetic separator invented by John Prince consisted of two pairs of electromagnets with a feed belt running over them Magnetic separation takes advantage of the differences in magnetic properties of minerals

Nov 01 2000 · In view of this physical separation techniques magnetic and high tension separation were used to separate out the majority of the cassiterite values from the primary gravity preconcentrate to obtain a predominantly wolframite–scheelite concentrate

Nov 18 2019 · Magnetic separators of various types are applied in the concentration of fine iron minerals taconites laundry black sands Wolframite and their separation of Sn cassiterite separation of ilmenite or magnetite from Ca phosphate minerals especially apatite or other nonmetallic minerals etc 3 Electrical conductivity

The mixed concentrate from the tables or other concentrators after being roasted to expel sulfur and arsenic if they are present is sent to a magnetic separator where the iron is first removed by a weak magnet and afterward the wolframite is removed by a stronger magnet the point that has caused trouble in this system of treatment is that the wolframite concentrate contains a good deal of cassiterite which adheres to the wolframite

Cassiterite is obtained from all three types of primary deposit but most is from placers within 2 km of their primary source Most wolfram is mined from quartz veins and greisen both colluvial and unweathered some wolfram is from pegmatites and a small amount from placers

This separation technique can be useful in mining iron as it is attracted to a magnet In mines where wolframite was mixed with cassiterite such as South Crofty and East Pool mine in Cornwall or with bismuth such as at the Shepherd and Murphy mine in Moina Tasmania magnetic separation was used to separate the ores

This separation technique can be useful in mining iron as it is attracted to a magnet In mines where wolframite was mixed with cassiterite such as South Crofty and East Pool mine in Cornwall or with bismuth such as at the Shepherd and Murphy mine in Moina Tasmania magnetic separation was used to separate the ores At these mines a device

Magnetic separation Magnetic Separation is which separating components of mixtures by using magnets to attract magnetically susceptible materials This separation technique can be useful in mining iron as it is attracted to a magnet In mines where wolframite was mixed with cassiterite such as South Crofty and East Pool mine in Cornwall or with bismuth such as at the Shepherd and Murphy mine in Moina Tasmania magnetic separation
