This allowed ancient ironworkers to process a much wider range of iron ores than modern industry can use. The archaeological significance of this study is that we show that the geological source of ore used at any smelting site in the Lowveld can be determined by chemical analysis or thin-section microscopy of the slag.

More Info. Ilmenite is an unremarkable stone that can be found in small quantities within gabbro and orthoclase. Though it is magma-safe, gabbro itself is also magma-safe. In the real world, ilmenite is often mined for production of titanium dioxide, a common white pigment. It can also be used as a source of iron . Ilmenite. [ show][ Select all]
