Patent ID: 7943103

Claim:
A process for handling waste solids produced from the chlorination of titanium-bearing ores in the presence of coke as a reducing agent, comprising: cooling a product stream from said chlorination of titanium-bearing ores which includes waste metal chloride solids and unreacted ore and coke solids; separating waste metal chloride solids and unreacted ore and coke solids from gaseous components of the product stream; combining the waste metal chloride solids and unreacted ore and coke solids with a liquid whereby waste metal chloride solids are dissolved in the liquid and unreacted ore and coke solids are slurried in the liquid; separating out unreacted ore and coke solids from the liquid including the dissolved waste metal chlorides; after separating out unreacted ore and coke solids from the liquid, dividing the liquid including the dissolved waste metal chlorides into a recycle substream or portion and a bleed substream or portion, the recycle substream or a portion of the recycle substream and the bleed substream or a portion of the bleed substream having a specific gravity of at least about 1.07; recycling the recycle substream or portion to comprise at least a part of the liquid which is combined with the waste metal chloride solids and unreacted ore and coke solids in the product stream; and neutralizing the bleed substream or portion to produce a filterable mass of waste metal hydroxide solids.
