Results and Discussion Investigations show that the derivatives of salicylic acid form colored complexes with transition metals [10] [7]and this can be used in developing an extractionphotometric methods for the determination of these metals, also of manganese (II). Condition ...
Lowgrade ore with a minimum of 40% manganese was acceptable at a considerably lower price if silica and iron contents were below 10% and 15% respectively. In addition to the grade requirements a size limit may have to be met by ores and concentrates. This generally stipulates an upper size limit (12 in.) and a percentage of plus 20 mesh material (often 75%). Finely .
Manganese ore is not found in pure form in nature but as a compound. It is most densely loed as a manganese mine.
