Abstract

PURPOSE: To blend automatically the dust slurry of ore to the raw material without causing the contamination and enable it to be reused, by separating the powdery or granular ore of slurry form to the coarse grains and fine particles and by obtaining the dust slurry of a definite quality by dehydrating the fine particles.
CONSTITUTION: The powdery or granular ore of slurry form is led to the coarse grains recovering tank 21 through the drainage through. In this tank 21, only the ore of coarse grains having grain size above about 1 mm is precipitated and this precipitate is accumulated on the pallet 23 through the classifier 22 and is conveyed to the yard with the truck 24. On the other hand, the ore of fine particles below 1 mm which has overflowed the tank 21, is fed to the thickener 26 after the trash, etc. has been removed with the screen 25. Then, after the ore of fine particles has precipitated, the dust slurry is concentrated to 45W60 wt.% by being dehydrated preliminarily with the pump 27. Then, this slurry is concentrated to 70W90 wt.% with the dehydrator 31 and is fed to the slurry tank 32. Then, this dust slurry is belnded to the raw material through the distributor 36, the belt conveyor 38 and the stacker 39
