1999-3-30  Manganese oxide minerals have been used for thousands of years—by the ancients for pigments and to clarify glass, and today as ores of Mn metal, catalysts, and battery material. More than 30 Mn oxide minerals occur in a wide variety of geological settings. They are major components of Mn nodules that pave huge areas of the ocean floor and bottoms of many fresh-water lakes.

CHAPTER 1 – INTRODUCTION

2018-1-20  In relation to the major African countries producing Manganese Ore, it is clear from Figure 1.4 below that South Africa produced the most Manganese Ore wet tons( ) over a 10 year period extending from 2001 to 2010. South Africa therefore plays an important role in the Manganese Industry, and the demand for Manganese Ore is definitely present .
