Title: Improvements in and relating to the manufacture of chromates of alkali metals
IPC: C01G37/14
Filed: 1946-07-30
Abstract: Alkali metal chromates are produced by roasting chrome ore, lime and an alkali, e.g. soda ash, in an oxidizing atmosphere, e.g. at 1050-1175 DEG  C. in a rotary kiln for 1-2 hours, leaching with water or dilute wash liquors from a previous operation, preferably at room temperature, and separating the solution from the insoluble residue before any substantial hydration of unhydrated compounds in the residue has taken place and before any substantial amount of calcium chromate has formed.  From 5 to 20 minutes from the mixing with water, &c. to the separation of the chromate liquid is specified. The insoluble residue is centrifuged to a moisture content of not more than 20 per cent, and allowed to stand for several hours, whereupon it becomes dry and free flowing, and may be mixed with a new furnace charge.
