 magnetite
mineral processing
1).
the crude ore first proceed the preliminary
broken through jaw crusher, generally
divide into coarse crushing and fine
crushing two stages; 2) the appropriate
stone size(10-20 mm) will be get from
the last process, then will be evenly
feed into the ball mill through the
elevator and mining feeder¡¡

 heavy
medium beneficiation
usually
we call the medium that greater than
the density of water as heavy medium,
so beneficiation in this medium called
heavy medium beneficiation. in the medium,
light mineral floats in the surface,
heavy mineral subsidence, then heavy
mineral (ore concentrate) and light
mineral (gangue) can be collected separately¡¡

 flotation
process
use physical and chemical properties
differences of mineral surface in the
mineral particles sorting process, formerly
known as method of flotation, which
is the most widely used method of mineral
processing. almost all the ore can use
the method of flotation, such as gold,
silver mine, galena, sphalerite¡¡ |

 express
way gravel production technology
both
asphalt and concrete pavement in the
express way in the use of sma or superpave
have strict requirement on the aggregate
grain shape, especially in the basalt
gravel content-flake, but the former
impact crushing processing technology
can not meet the requirements, .¡¡ |
