iron processing

Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is ...

Process for treating siderite

Siderite is an ore of iron which in pure form is iron carbonate (FeCO3), although in the form 1I of ore it ordinarily contains sulphides and various gangue material. One of the principal features of my invention resides in the manner in which the siderite is decomposed and the several constituents are recovered in a highly purified and concentrated state.
