Lean iron ores may contain 26 % iron min.

  • How To Get Sulfur Primitive Skills

    The two pots are connected by a short pipe. The crushed rocks are placed in one pot. This pot is heated to a very high temp. The sulfur would evaporate and the fumes would then flow into the other pot via the pipe, where it would cool and condense. Any slag (mostly iron) left in the first pot can be discarded or used if you have any use for iron.

  • Smelting and Roasting Ores to recover gold silver and

    Some prospectors are interested in the methods of processing sulfide ores to extract their values. The two of the best known processes are smelting and roasting.
