Abstract
1301298 Blast furnace distillation of zinc IMPERIAL SMELTING CORP (NSC) Ltd 18 Nov 1970 [3 Dec 1969] 59141/69 Heading C7D [Also in Division C5] In the extraction of Zn from a blast furnace charge of oxidic Zn and /or oxidic Zn/Pb materials with a carbonaceous fuel and reducing agent, the carbonaceous fuel, preferably coke, is first treated to reduce its reactivity to CO 2 at 1000C. The treatment comprises forming a physical barrier layer on the coke or briquetted carbonaceous fuel by treatment e.g. spraying either with a solution or suspension of an inorganic acid, base or salt e.g. boric acid, borax, CaO, Ca(OH) 2 , CaCO 3 , Na 2 SiO 3 , or with molten tar or pitch. Alternatively the inorganic barrier material may be incorporated in the briquette. The treated coke is then preheated to form the barrier layer. In the case of the inorganic material it may be sprayed onto the hot preformed carbonaceous briquettes. The preferred treatment involves spraying the coke with a 2.5% aqueous solution of boric acid.
