Dephosphorization method for dephosphorization of rare earth concentrate

The invention discloses a method for decomposing rare earth concentrates, in particular to a method for decomposing rare earth concentrates by reverse leaching. The process steps include: filtration, drying, roasting and magnetic separation. The utility model is characterized in that: first, reverse leaching and impurity removal, the water-soluble substance is first dissolved by dilute hydrochloric acid, and the rare earth element is left in the leaching residue; then the leaching residue is filtered and dried, and then oxidized and roasting is performed; Rare earth minerals are selected under the magnetic field strength. The object of the present invention is to provide a rare earth concentrate decomposition method with low raw material consumption, low production cost and high rare earth recovery rate.

Cylinder

Cylinder is the place where the fuel-air mixture is compressed and burned to convert chemical energy to heat and mechanical energy to make the bike go. Just like in any other internal combustion engine. The engine might have only one cylinder or many. More than four is rare, though.The cylinder is fired by a spark plug which creates a spark electrically from the battery .
