the reduction and liquidus behaviour of manganese slag with different basicities were studied in non-isothermal experiments in the temperature range of 14001500 c. certain amounts of quartz were added to assmang ore (south africa), and lime was added to comilog ore (gabon), to adjust the charge basicity to 0.5, 0.8 and 1.2. the extent of manganese ore reduction as a
in 1940, assmang acquired a manganese ore outcrop on a small hillock known as black rock. several large properties underlain by ore were subsequently found and acquired. manganese ore mining operations were extended and today include 3 underground mining complexes gloria (commissioned in 1975) and producing medium grade semi-carbonate ore.
quartz, hc femn slag or limestone were added to assmang or comilog according to the simn production charge, and mass loss results were obtained by using a tga furnace. the results showed that particle size, type of manganese ore and mixture have close relationship to the reduction behavior of raw materials during mno and sio 2 reduction.
in 2010 assmangs conversion of some of the furnaces at machadodorp works from charge chrome to ferro manganese started. in july 2010 furnace 5 was successfully converted to high carbon ferro manganese. the first manganese alloy from this furnace was exported in october of the same year. since then a further two furnaces were successfully converted.
