Manganese. Total recorded production of manganese ore in South Australia is estimated at 62 000 t, mainly from residual deposits, with half of this coming from Pernatty Lagoon. The last recorded production was in 1951. The only recorded resource is for Pernatty lagoon of 167,500 tonne at 20% Mn.
Mineralogy Composition of Ore. The mineralogy composition of ore is determined by optical microscope and electron microprobe ("EPMA" for short) combined with Xray diffraction analysis. According to the results given in Table 1, manganese minerals of this ore are mainly lithiophorite, followed by pyrolusite.
