- a slurry thereby further reducing the density and stabilising the froth.
- a slurry thereby further reducing the density and stabilising the froth.
- a slurry thereby further reducing the density and stabilising the froth.
- the method preferably comprises the further step of separating the desired minerals
- the separation process preferably
- microwave heating includes one or more of: microwave heating; ultrasonic separation; cyclone separation; flotation; spraying; electrostatic precipitation; filtration; and drying.
- a return pipe line flows upstream from the separation
- the pumping step is performed by a twin
- the invention provides an apparatus for transportation
- said apparatus comprising crushing means to crush the ore into relatively
- mixing means to mix the crushed ore with a liquid carrier to form a relatively
- injection means to inject a gas into the slurry thereby to aerate

- Figure 9 is a diagrammatic view showing the pumping station connected to a fluid
- the ore is initially processed, crushed and reduced to relatively fine particles in a conventional processing plant 1.
- the crushed ore is then fed to
- a belt conveyor 2 for transportation to a mixer 3.
- the crushed ore is mixed
- liquid carrier which may be mine water for example
- the mixer includes programmable metering devices and feeders (not shown) for the crushed minerals, oxides or concentrates, the liquid carrier, flocculating agents, plasticisers, lubricants and other components required to optimise the pumping
- the slurry is fed from the mixer 3 to a post-treatment station (not shown)
- flow monitoring device 5 A is positioned downstream of the pumping station to permit
- the pipe line terminates at a separation station 7 from which the ore 8 is recovered.
- the separation station 7 is shown diagrammatically as a cyclone separator. It will be
- flotation, spraying, electrostatic precipitation, filtration and drying may be used in order to
- the overflow from the separation station is directed to a
- the recovered flocculant, carrier liquid, and other additives may be reused.
- the dense slurry forms the walls of a
