A method of processing a ferroalloy waste slag in a reactor which includes the steps of treating the slag with a metallic reductant and a conditioning flux to release a metal oxide and reduce it to metallic form, to use as a commercially acceptable silicon-containing alloy and to form a waste slag which is detoxified by means of granulation and separating the detoxified slag from silicon ...The reduction and liquidus behaviour of manganese slag with different basicities were studied in non-isothermal experiments in the temperature range of 1400–1500 °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 function temperature ...

Introduction Manganese is one ofthe most widely used alloying materi als in modern steel production. It is also used in non-ferrous metallurgy. As a strategic and critical material, the optiManganese slag is a by-product of ferromanganese alloy manufacturing. Two kinds of slag can be generated in the production of ferromanganese and ferromanganese–silicon alloys: air-cooled slag also known as lumpy slag, and water-cooled slag also known as granulated slag. 90 Approximately 900 kg of manganese slag is generated per tonne of ferromanganese alloy produced, 90 and the global ...
