摘要
A process is provided for handling waste solids produced from the chlorination of titanium-bearing ores in the presence of coke as a reducing agent. The process includes the steps of combining 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, and separating out the unreacted ore and coke solids from the liquid. The liquid including the dissolved waste metal chlorides is then divided into a recycle substream and a bleed substream. The recycle substream is recycled such that it comprises 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. The bleed substream is neutralized to produce a filterable or directly landfillable mass of waste metal hydroxide solids.
