  • Process for treatment of antimony-containing materials
    Patent number: 4174372
    Abstract: A process for treatment of antimony-containing materials in a fluidized bed by way of calcination of the materials at a temperature within the range of from 800.degree. to 1,100.degree. C. obtained by combusting a mixture of a fuel gas and an oxygen-containing gas in said fluidized bed. Said mixture of the gases is formed directly in said fluidized bed by supplying, thereinto, the fuel gas and oxygen-containing gas in separated streams uniformly distributed over the bottom cross-section of said fluidized bed so that the fuel gas stream is surrounded over the entire perimeter by the oxygen-containing gas streams.The process according to the present invention makes it possible to treat antimony-containing materials with a content of antimony ranging from 0.3 to 15% by weight and to obtain antimony-rich sublimates with a content of antimony as high as 40 to 75% by weight.
