This paper explains the principle of the new sustained shockwave plasma (SSP) reactor, which achieves in-flight reduction of minerals. Initial research is described in which an open 40 kW SSP reactor is used to assess the feasibility of in-flight reduction of a low-grade, domestic chromite concentrate. The effect of feed and operating conditions are discussed and a reduction mechanism based on both conventional theory and conditions thought to exist within the sustained shockwave plasma is postulated. In conclusion, the ongoing research program at the Mineral Resources Research Center (MRRC) and the potential for plasma processing of minerals are outlined.
