| Abstract Scope |
Manganese ores are used as raw materials in the production of manganese ferroalloys. The lack of knowledge about mineralogical and metallurgical properties of manganese ores is a common problem in the production of these alloys. Decrepitation, which is the breakage of ores particles upon heating, is an important quality parameter. This work focuses on how the chemical, physical, and mineralogical properties of South African manganese ores and experimental parameters influence the decrepitation. The study is done on ore A, ore B and the blend of the two with a ratio of A to B being 60:40. After characterization the samples were then tested for decrepitation in a rotary kiln, temperature and rotational speed were varied between 600-1000°C and 5–20 rpm respectively, with the residence time of 30 minutes. The purpose of this paper is to describe the research method in detail and to report on preliminary results achieved |
